  • Automatic music rating based on listening habits

    - by marco92w
    I've created a Winamp-like music player in Delphi. Not so complex, of course. Just a simple one. But now I would like to add a more complex feature: Songs in the library should be automatically rated based on the user's listening habits. This means: The application should "understand" if the user likes a song or not. And not only whether he/she likes it but also how much. My approach so far (data which could be used): Simply measure how often a song was played per time. Start counting time when the song was added to the library so that recent songs don't have any disadvantage. Measure how long a song was played on average (minutes). Starting a song but directly change to another one should have a bad influence on the ranking since the user didn't seem to like the song. ... Could you please help me with this problem? I would just like to have some ideas. I don't need the implementation in Delphi.

  • Delphi: Error when starting MCI

    - by marco92w
    I use the TMediaPlayer component for playing music. It works fine with most of my tracks. But it doesn't work with some tracks. When I want to play them, the following error message is shown: Which is German but roughly means that: In the project pMusicPlayer.exe an exception of the class EMCIDeviceError occurred. Message: "Error when starting MCI.". Process was stopped. Continue with "Single Command/Statement" or "Start". The program quits directly after calling the procedure "Play" of TMediaPlayer. This error occurred with the following file for example: file size: 7.40 MB duration: 4:02 minutes bitrate: 256 kBit/s I've encoded this file with a bitrate of 128 kBit/s and thus a file size of 3.70 MB: It works fine! What's wrong with the first file? Windows Media Player or other programs can play it without any problems. Is it possible that Delphi's TMediaPlayer cannot handle big files (e.g. 5 MB) or files with a high bitrate (e.g. 128 kBit/s)? What can I do to solve the problem?

  • Any open source editor to make video games online without programming knowledge?

    - by chelder
    With Scratch we can create video games online, from its web platform, and publish them on the same web. I could download its source code and use it, as many others already did (see Scratch modifications). Unfortunately, we need programming knowledge to use it. Actually, Scratch is mainly for teaching kids to code. I also found editors like Construct 2, GameSalad Creator and many others (just type on Google: create a video game without programming). With those editors we can create video games without coding. Unfortunately they are neither open source nor web platform. They need to be installed on Windows or Mac. Do you know some editor like Construct 2 or GameSalad Creator but open source and executable from a web server? Maybe some HTML5 game engine can do it?

  • Does VLC Player work well on Windows 7 64-bit?

    - by ????
    I tried VLC Player on Windows 7 64-bit version and the playback was fine, but when the video is maximized the image is very pixelated. I tried this on a Radeon HD 2600 XT graphics card as well as a computer with an Intel graphics chipset and both have the same result. If I use VLC Player on Windows 7 32-bit instead of 64-bit, there is no pixelation. Is this a known problem or is there any method to fix it on Windows 7 64-bit? Update: there isn't a 32-bit vs 64-bit version of VLC player, is there? (unlike 7-Zip) I also tried GOM Player and it doesn't have the problem on Windows 7 64-bit. Update: Nov 4, 2009 VLC displays an update notice: VLC 1.0.3 is a minor release fixing many bugs, especially for Windows Vista and 7, but it also introduces 2 new modes for deinterlacing, and a new udev module. Major fixes are about WMA Pro support, Dolby tracks in 4.0, v4l/v4l2 and atsc and a crash in mjpeg demuxer. Update of translations are also part of this release.

  • Caching with AVPlayer and AVAssetExportSession

    - by tba
    I would like to cache progressive-download videos using AVPlayer. How can I save an AVPlayer's item to disk? I'm trying to use AVAssetExportSession on the player's currentItem (which is fully loaded). This code is giving me "AVAssetExportSessionStatusFailed (The operation could not be completed)" : AVAsset *mediaAsset = self.player.currentItem.asset; AVAssetExportSession *es = [[AVAssetExportSession alloc] initWithAsset:mediaAsset presetName:AVAssetExportPresetLowQuality]; NSString *outPath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"out.mp4"]; NSFileManager *fileManager = [NSFileManager defaultManager]; [fileManager removeItemAtPath:outPath error:NULL]; es.outputFileType = @"com.apple.quicktime-movie"; es.outputURL = [[[NSURL alloc] initFileURLWithPath:outPath] autorelease]; NSLog(@"exporting to %@",outPath); [es exportAsynchronouslyWithCompletionHandler:^{ NSString *status = @""; if( es.status == AVAssetExportSessionStatusUnknown ) status = @"AVAssetExportSessionStatusUnknown"; else if( es.status == AVAssetExportSessionStatusWaiting ) status = @"AVAssetExportSessionStatusWaiting"; else if( es.status == AVAssetExportSessionStatusExporting ) status = @"AVAssetExportSessionStatusExporting"; else if( es.status == AVAssetExportSessionStatusCompleted ) status = @"AVAssetExportSessionStatusCompleted"; else if( es.status == AVAssetExportSessionStatusFailed ) status = @"AVAssetExportSessionStatusFailed"; else if( es.status == AVAssetExportSessionStatusCancelled ) status = @"AVAssetExportSessionStatusCancelled"; NSLog(@"done exporting to %@ status %d = %@ (%@)",outPath,es.status, status,[[es error] localizedDescription]); }]; How can I export successfully? I'm looking into copying mediaAsset into an AVMutableComposition, but haven't had much luck with that either. Thanks! PS: Here are some questions from people trying to accomplish the same thing (but with MPMoviePlayerController): Cache Progressive downloaded content in MPMoviePlayerController Simultaneously stream and save a video?

  • Actionscript: NetStream stutters after buffering.

    - by meandmycode
    Using NetStream to stream content from http, I've noticed that esp with certain exported h264's, if the player encounters an empty buffer, it will stop and buffer to the requested length (as expected). However once the buffer is full, the playback doesn't resume, but instead jumps ahead, as such- instantly playing the buffered duration in a brief moment, and thusly triggering an empty buffer again.. this will then continue over and over. Presumably when the netstream pauses to buffer, the playhead position continues, and the player is attempting to snap to that position on resume- however given it could take 5 seconds to build a 2 second buffer- it ends up with a useless buffer again.. (this is an assumption) I've attempted to work around this by listening for an empty buffer netstatus event, pausing the stream, and at the same time setting up a loop to check the current buffer length vs the requested buffer length.. and resuming once the buffer length is greater than or equal to the requested buffer.. however this causes problems when there isn't enough of the video remaining.. for example, a 10 second buffer with only 5 seconds remaining, the loop just sits there waiting for a buffer length of 10 seconds when theres only 5 left... You would think that you could simply check which was smaller, the time left or the requested buffer length.. however the times flash gives are not accurate.. If you add the net streams current time index, plus the buffered time, the total is not the entire duration of the movie (when at the end).. it is close but not the same. This brings me back to the original problem, and if there is another way to fix this, clearly flash knows when the buffer is ready, so how can i get flash pause when it buffers, and resume once the buffer is ready? currently it doesn't.. it pauses and then once the buffer is full- it plays the entire buffered content in about .1 of a second. Thanks in advance, Stephen.

  • H.264 / FLV best practices for HTML

    - by Steve Murch
    I run a website with about 700 videos (And no, it's not porn -- get your mind out of the gutter :-) ). The videos are currently in FLV format. We use the JWPlayer to render those videos. IIS6 hosted. Everything works just fine. As I understand it, H.264 (not FLV and likely not OGG) is the emerging preferred HTML5 video standard. Today, the iPad really only respects H.264 or YouTube. Presumably, soon many more important browsers will follow Apple's lead and respect only the HTML5 tag. OK, so I think I can figure out how to convert my existing videos into the proper H.264 format. There are various tools available, including ffmpeg.exe. I haven't tried it yet, but I don't think that's going to be a problem after fiddling with the codec settings. My question is more about the container itself -- that is, planning graceful transition for all users. What's the best-practice recommendation for rendering these videos? If I just use the HTML5 tag, then presumably any browser that doesn't yet support HTML5 won't see the videos. And if I render them in Flash format via the JWPlayer or some other player, then they won't be playable on the iPad. Do I have to do ugly UserAgent detection here to figure out what to render? I know the JWPlayer supports H.264 media, but isn't the player itself a Flash component and therefore not playable on the iPad? Sorry if I'm not being clear, but I'm scratching my head on a graceful transition plan that will work for current browsers, the iPad and the upcoming HTML5 wave. I'm not a video expert, so any advice would be most welcome, thanks.

  • Playing flash video with ASP.NET MVC

    - by evan
    What's a good flash player to use on an ASP.NET MVC site? The page I'm working on will need to display a number of videos on each page dynamically based on what the user searched for. I'd like each of the videos to show up as thumbnails that can be played, paused, and or enlarged to full screen. I've worked with the standard ASP.NET and used FlashControl.dll to accomplish this. Are there better ways than using a user control for MVC pages? Any tips on including video in webpages in general? Thanks in advance!

    I have created a simple app for my client with his selection of youtube videos embedded via iframe player and html5. The app got approved in android store whereas itunes rejected it claiming below, "Apps may not use protected third party material such as trademarks, copyrights, patents or violate 3rd party terms of use. Authorization to use such material must be provided upon request" Below is the link for the app in android. https://play.google.com/store/apps/details?id=com.jayam.shortfilms While I share videos using the html code obtained from youtube share button, still apple is claiming that I should provide evidence of copyright from each video owner. Any experiences of this kind will be very helpful for me.

  • Is Protune for video only or may be used for photo too?

    - by Green
    I have Hero3+ Black Edition. I can't understand if Protune is for video only or may be applied for photos? The manual says it is both for video and for photo (page 35): High-Quality Image Capture Protune’s high data rate captures images with less compression, giving content creators higher quality for professional productions. Film/TV Rate Standard While shooting in Protune, you have the option of recording video in cinema quality 24 fps to easily intercut GoPro content with other source media without the need to perform fps conversion. But at the same time their site says that Protune is for video only: To record Protune footage, you’ll need to turn Protune ON in your camera’s settings menu. What for is Protune? Photo? Video? Or both?

  • Does a dedicated video card improve HTML5 websites, Skype or Flash games performance?

    - by Kiewic
    I have read that having a dedicated video card (GPU) improves performance if you use your computer to play video games. I guess to make this happen, video games or apps must be using especial libraries designed to share the workload with the GPU, maybe Direct X or OpenGL, I don't know. Am I wrong? So, can HTML5 websites, Adobe Illustrator, Flash games (Zynga games), Skype or Netflix benefit from a dedicated video card? I usually do the previous activities simultaneously. Should I consider changing from an integrated video card to a dedicated card if I want to improve performance? Thanks.

  • Android: OutOfMemoryError while uploading video...

    - by AP257
    Hi all, I have the same problem as described here, but I will supply a few more details. While trying to upload a video in Android, I'm reading it into memory, and if the video is large I get an OutOfMemoryError. Here's my code: // get bytestream to upload videoByteArray = getBytesFromFile(cR, fileUriString); public static byte[] getBytesFromFile(ContentResolver cR, String fileUriString) throws IOException { Uri tempuri = Uri.parse(fileUriString); InputStream is = cR.openInputStream(tempuri); byte[] b3 = readBytes(is); is.close(); return b3; } public static byte[] readBytes(InputStream inputStream) throws IOException { ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); // this is storage overwritten on each iteration with bytes int bufferSize = 1024; byte[] buffer = new byte[bufferSize]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { byteBuffer.write(buffer, 0, len); } return byteBuffer.toByteArray(); } And here's the traceback (the error is thrown on the byteBuffer.write(buffer, 0, len) line): 04-08 11:56:20.456: ERROR/dalvikvm-heap(6088): Out of memory on a 16775184-byte allocation. 04-08 11:56:20.456: INFO/dalvikvm(6088): "IntentService[UploadService]" prio=5 tid=17 RUNNABLE 04-08 11:56:20.456: INFO/dalvikvm(6088): | group="main" sCount=0 dsCount=0 s=N obj=0x449a3cf0 self=0x38d410 04-08 11:56:20.456: INFO/dalvikvm(6088): | sysTid=6119 nice=0 sched=0/0 cgrp=default handle=4010416 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:~93) 04-08 11:56:20.456: INFO/dalvikvm(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.456: INFO/dalvikvm(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.456: INFO/dalvikvm(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.467: WARN/dalvikvm(6088): threadid=17: thread exiting with uncaught exception (group=0x4001b180) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): Uncaught handler: thread IntentService[UploadService] exiting due to uncaught exception 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): java.lang.OutOfMemoryError 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.expand(ByteArrayOutputStream.java:93) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:218) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.readBytes(UploadService.java:199) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.getBytesFromFile(UploadService.java:182) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.doUploadinBackground(UploadService.java:118) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at com.android.election2010.UploadService.onHandleIntent(UploadService.java:85) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.app.IntentService$ServiceHandler.handleMessage(IntentService.java:30) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Handler.dispatchMessage(Handler.java:99) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.Looper.loop(Looper.java:123) 04-08 11:56:20.467: ERROR/AndroidRuntime(6088): at android.os.HandlerThread.run(HandlerThread.java:60) 04-08 11:56:20.496: INFO/Process(4657): Sending signal.

But (newbie question alert) does that mean that I should make multiple PostMethod requests, and glue the file together at the server end? Or can I load the bytestream into memory in chunks, and glue it together in the Android code? If anyone could give me a clue as to the best approach, I would be very grateful.

  • Catching MediaPlayer Exceptions from WPF MediaElement Control

    - by ScottCate
    I'm playing video in a MediaElement in WPF. It's working 1000's of times, over and over again. Once in a blue moon (like once a week), I get a windows exception (you know the dialog Dr. Watson Crash??) that happens. The MediaElment doesn't expose an error, it just crashes and sits there with an ugly Crash report on the screen. If you "view this report" you can see it is in fact MediaPlayer that has crashed. I know I can disable the crash reports from popping up - but I'm more interested in finding out what's going wrong. I'm not sure how to capture the results of the Dr. Watson capture, but I have the dialog open now if someone has advice on a better way to capture. Here is the opening line of data, that points to my application, then to wmvdecod.dll AppName: ScottApp.exe AppVer: 2.2009.2291.805 AppStamp:4a36c812 ModName: wmvdecod.dll ModVer: 11.0.5721.5145 ModStamp:453711a3 fDebug: 0 Offset: 000cbc88 And from the Win Event Log.

  • Making a non-trivial Image and Video Gallery with a really nice interface

    - by Cawas
    Short part: I'm starting to build an Image and Video Gallery for our intranet. It's pretty much like an image gallery with video thumbnails that play on click. It's just good to keep that in mind because caching and streaming happen in very different ways there. It will serve to browse our reference database, which will also contain searching, tagging and voting. There are 3 features that I need to begin with: Quick preview of thumbnails from each Gallery Fast zoom in / out Animated scrolling Now to the long part, since I can't seem to reduce this: I hope this question belongs here. Maybe people can read this through and identify with it, specially since I expect answers to be pretty specific. The first plan was getting Apple's mobile me gallery as base, because it just so happens to have all those 3 features. If you've never seem it, you should check it out. Move the mouse over each collection and you'll get a nice preview "per pixel". Carousel got a really good scrolling, not just because of the pretty effect. I like it much more than cooliris, but it would be nice to have it in several rows, maybe without the magnifying effect... Then it could be all in the same place with the zoom. The more the features blend-in together, the better. Zooming out with the mouse, scrolling by dragging, once the zoom is really out it becomes a browsing through galleries, with the quick-show preview of each, all properly cached and fast. That'd be perfect. A very compelling interface will be important in this project. Well, my point here is just describing what I need and hope to hear from people with more experience in all that stuff of what's already done and what I'd have to do myself. And how (i.e. which framework to use) to do it. To begin with, I've found a gallery demo and its source code (I think it was from here, but the link seems broken now). I guess it was made in SproutCore, which is what mobileme was based upon. Definitely with JQuery (which already seems a little slow). But I'm still missing two features there: the carousel and the fast zoom (it's just not as slow as the zoom in this demo with cappuccino). Then I've found a supposedly better one with a pretty good and similar zoom, that I'm not sure if it's using any framework and is already in php. Right now it'd be better having just the HTML, no server-side, since I'm building interface first. So, can anyone point directions? There are way too many options! Should I look for another solution closer to what I need, or try and tweak this one? I'm not familiar with any framework at all. Sorry for bringing this question that I will have to answer myself anyway sooner or later and sorry that I couldn't make this smaller. Thanks.

    Hey,I use GData try to upload my video to youtube, but meet these error: serviceBase:<GDataServiceGoogleYouTube: 0x2435f0> objectFetcher:<GDataHTTPUploadFetcher: 0x26dca0> failedWithStatus:403 data:<errors xmlns='http://schemas.google.com/g/2005'> <error> <domain>GData</domain> <code>ServiceForbiddenException</code> <internalReason>Currently authenticated user does not have write access to desrender&apos;s videos.</internalReason> </error> </errors> * is my youtube account. Following is the code: - (GDataServiceGoogleYouTube *)youTubeService { static GDataServiceGoogleYouTube* service = nil; if (!service) { service = [[GDataServiceGoogleYouTube alloc] init]; [service setShouldCacheDatedData:YES]; [service setServiceShouldFollowNextLinks:YES]; [service setIsServiceRetryEnabled:YES]; } // update the username/password each time the service is requested NSString *username = [mUsernameField text]; NSString *password = [mPasswordField text]; if ([username length] > 0 && [password length] > 0) { [service setUserCredentialsWithUsername:username password:password]; } else { // fetch unauthenticated [service setUserCredentialsWithUsername:nil password:nil]; } NSString *devKey = [mDeveloperKeyField text]; [service setYouTubeDeveloperKey:devKey]; return service; } - (IBAction)uploadPressed:(id)sender { NSString *devKey = [mDeveloperKeyField text]; GDataServiceGoogleYouTube *service = [self youTubeService]; [service setYouTubeDeveloperKey:devKey]; NSString *username = [mUsernameField text]; NSString *clientID = [mClientIDField text]; NSURL *url = [GDataServiceGoogleYouTube youTubeUploadURLForUserID:username clientID:clientID]; // load the file data NSString *path = [[NSBundle mainBundle] pathForResource:@"YouTubeTest" ofType:@"m4v"]; NSData *data = [NSData dataWithContentsOfFile:path]; NSString *filename = [path lastPathComponent]; // gather all the metadata needed for the mediaGroup NSString *titleStr = [mTitleField text]; GDataMediaTitle *title = [GDataMediaTitle textConstructWithString:titleStr]; NSString *categoryStr = [mCategoryField text]; GDataMediaCategory *category = [GDataMediaCategory mediaCategoryWithString:categoryStr]; [category setScheme:kGDataSchemeYouTubeCategory]; NSString *descStr = [mDescriptionField text]; GDataMediaDescription *desc = [GDataMediaDescription textConstructWithString:descStr]; NSString *keywordsStr = [mKeywordsField text]; GDataMediaKeywords *keywords = [GDataMediaKeywords keywordsWithString:keywordsStr]; BOOL isPrivate = mIsPrivate; GDataYouTubeMediaGroup *mediaGroup = [GDataYouTubeMediaGroup mediaGroup]; [mediaGroup setMediaTitle:title]; [mediaGroup setMediaDescription:desc]; [mediaGroup addMediaCategory:category]; [mediaGroup setMediaKeywords:keywords]; [mediaGroup setIsPrivate:isPrivate]; NSString *mimeType = [GDataUtilities MIMETypeForFileAtPath:path defaultMIMEType:@"video/mp4"]; // create the upload entry with the mediaGroup and the file data GDataEntryYouTubeUpload *entry; entry = [GDataEntryYouTubeUpload uploadEntryWithMediaGroup:mediaGroup data:data MIMEType:mimeType slug:filename]; SEL progressSel = @selector(ticket:hasDeliveredByteCount:ofTotalByteCount:); [service setServiceUploadProgressSelector:progressSel]; GDataServiceTicket *ticket; ticket = [service fetchEntryByInsertingEntry:entry forFeedURL:url delegate:self didFinishSelector:@selector(uploadTicket:finishedWithEntry:error:)]; [self setUploadTicket:ticket]; } It almost same as GData's YouTubeSample.. Someone help me!!!!

  • Has a multi player graphic adventure* ever been made?

    - by Petruza
    By graphic adventure, I mean point & click LucasArts-type games. Those games have a mostly linear structure in nature, and usually don't offer as many variants as other games types like action, rpg, strategy, which makes this genre difficult to implement a multi-player feature. I'd like to know if there has been any attempts on doing such a thing, and if it would be viable, as players going offline or leaving a game in the middle would affect significantly the other players' game.

  • How to properly do weapon cool-down reload timer in multi-player laggy environment?

    - by John Murdoch
    I want to handle weapon cool-down timers in a fair and predictable way on both client on server. Situation: Multiple clients connected to server, which is doing hit detection / physics Clients have different latency for their connections to server ranging from 50ms to 500ms. They want to shoot weapons with fairly long reload/cool-down times (assume exactly 10 seconds) It is important that they get to shoot these weapons close to the cool-down time, as if some clients manage to shoot sooner than others (either because they are "early" or the others are "late") they gain a significant advantage. I need to show time remaining for reload on player's screen Clients can have clocks which are flat-out wrong (bad timezones, etc.) What I'm currently doing to deal with latency: Client collects server side state in a history, tagged with server timestamps Client assesses his time difference with server time: behindServerTimeNs = (behindServerTimeNs + (System.nanoTime() - receivedState.getServerTimeNs())) / 2 Client renders all state received from server 200 ms behind from his current time, adjusted by what he believes his time difference with server time is (whether due to wrong clocks, or lag). If he has server states on both sides of that calculated time, he (mostly LERP) interpolates between them, if not then he (LERP) extrapolates. No other client-side prediction of movement, e.g., to make his vehicle seem more responsive is done so far, but maybe will be added later So how do I properly add weapon reload timers? My first idea would be for the server to send each player the time when his reload will be done with each world state update, the client then adjusts it for the clock difference and thus can estimate when the reload will be finished in client-time (perhaps considering also for latency that the shoot message from client to server will take as well?), and if the user mashes the "shoot" button after (or perhaps even slightly before?) that time, send the shoot event. The server would get the shoot event and consider the time shot was made as the server time when it was received. It would then discard it if it is nowhere near reload time, execute it immediately if it is past reload time, and hold it for a few physics cycles until reload is done in case if it was received a bit early. It does all seem a bit convoluted, and I'm wondering whether it will work (e.g., whether it won't be the case that players with lower ping get better reload rates), and whether there are more elegant solutions to this problem.
