  • Detecting Available Qualities of YouTube Videos

    - by Langdon
    I'm writing a Boxee app that makes use of YouTube videos and I want to be able to display the highest quality version available. I was looking through the YouTube API, but I can't seem to find a way to detect if 720p and/or 1080p versions of the video are available. Does anyone know how to do this? I'm already using their Data API to collection information about the video, but there doesn't seem to be anything in the payload about different qualities consumable on the web: http://gdata.youtube.com/feeds/api/videos/NWHfY_lvKIQ I could just hard code fmt=22 and let it default to a lesser quality version, but then I miss out on 1080p (fmt=387).

  • use java-ffmpeg wrapper, or simply use java runtime to execute ffmpeg?

    - by user156153
    I'm pretty new to Java, need to write a program that listen to video conversion instructions and convert the video once an new instruction arrives (instructions is stored in Amazon SQS, but it's irrelevant to my question) I'm facing a choice, either use Java RunTime to exec 'ffmpeg' conversion (like from command line), or I can use a ffmpeg wrapper written inJava http://fmj-sf.net/ffmpeg-java/getting%5Fstarted.php I'd much prefer using Java Runtime to exec ffmpeg directly, and avoid using java-ffmpeg wrapper as I have to learn the library. so my question is are there any benefits using java-ffmpeg wrapper over exec ffmpeg directly using Runtime? I don't need ffmpeg to play videos, just convert videos Thanks

  • Load different views depending on the category of data on tap of tableview cell iPhone sdk

    - by neha
    Hi all, In my aplication, I want a tableview with different cell structure depending upon the category of data that's getting loaded in it [I have different categories like video, editorial etc with different structure of data like video has a single label, editorial has 3 labels etc]. I can load different nib files based on the data coming from xml parser. Now when the cell is tapped, I want to show its detailed view on a new viewController. So my question is is it possible to use only 1 viewController show different fields depending upon the category of data in the cell. Or do I need to create different viewControllers for each of the categories?

How would i do this? are there utils i can use to extract data from models? how about drawing the models? my server does not have a desktop or video card, would no video HW be a problem?

  • how do copyright permission systems for content hosting sites work?

    - by zebraman
    I am wondering about subscription sites that host content, like recorded performances from concerts. I'm sure there is a tangle of copyright permissions that must be granted for these video/audio files to be hosted. For example, if a band plays a cover of another band's song, permission must be obtained from not only the band that performed, but the band that owns the song. Perhaps even from the venue that hosted the performance, to record the video and post the content. I am curious how websites that host content like this work. How might an automated copyright system work to keep track of who has ownership of certain performances and obtain permission from said owners to record and post their content.

  • PC reboots spontaenously: debugging tips [closed]

    - by aaron
    I swapped my core 2 duo for a quad core recently, and generally things run fine, but every now and then my computer just restarts. I don't even get a blue screen (Vista 32). Core temp isn't a problem. My thinking is that my power supply is inadequate, but I haven't been able to test that (one idea was to under clock the cpu to see if that helped, but going up in speed was the only simple thing to do in the BIOS) Two cases where I semi-consistanly get problems: - Borderlands windowed after some period of time (and some other games, but Borderlands does it pretty regularly) - watching a video (e.g. quicktime/vlc) and having another video running Another thought is non-cpu heat? Maybe the graphics card? Any thoughts on how to track this down appreciated. Thanks!

  • Multimedia content in REST responce(XML/JSON)

    - by Koushik
    In my thesis I need to test different architectures. A request to a REST web service developed using Apache CXF and Spring MVC with MySQL as back end serving references(a field in database) to images,audio and video files stored in file system. In the response message, what is the best method to send the content to the client(another application using the service which I developed). URI: http://www.filmservices.com/film/{id} A client here is not the end user. Send the encoded hyperlink's(where the content is stored in the file system) to the client, so that the client renders the response and displays it to the browser. Use Base64 to encode the message(image,audio,video) and send it to the client. Main concern is performance.

  • Getting camera preview data without using a preview callback

    - by velocipedestrian
    I have an app that does some processing to camera preview frames before displaying them to the user. I'm currently using preview callbacks to access the image data, but the problem I have is that the onPreviewFrame() function stops getting called if you start recording video using a MediaRecorder, and I want the processing to continue when video is being recorded. I've tried doing the following: public static Bitmap convertViewToBitmap(View view) { Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),view.getHeight(), Bitmap.Config.ARGB_8888); view.draw(new Canvas(bitmap)); return bitmap; } to convert the preview surface to a bitmap, but when I pass the preview SurfaceView to the function it returns an all-black bitmap (it works when I test it on normal views though). Is there any other way I can access the image data if preview callbacks are not available?

  • Creating reference movies for iPhone on the fly

    - by Mad Oxyn
    We are working on an online mobile video app. The videos we want to play on mobile phones are being generated by a server, as there can be dynamic content in the server (based on user input). Now for iPhone we would like to play the video in the best possible resolution based on the connection speed at the time of downloading the movie. This can be done using reference movies. However, because our videos are being generated on the fly, we need to generate this reference movie on the fly as well. Is there a way to generate reference movies on the fly on a Linux server using some command line tool, PHP or Java? Or on a DOS server maybe? Any help will be much appreciated.

  • How to know when the MPMoviePlayerController has been paused in iPhone?

    - by iPhoney
    I want to add an overlay view for my video when the video is paused by the user. Is there any way to get the pause notification from MPMoviePlayerController? According to Apple Doc, there should be ways to do this but I can't find which notification should I use for this purpose. Quote: In addition to being notified when playback finishes, interested clients can be notified in the following situations: -When the movie player begins playing, is paused, or begins seeking forward ... For more information, see the Notifications section in this reference.

  • Which is the best API/Library to use when accessing a WebCam in .Net?

    - by Doctor Jones
    Which is the best API to use when accessing a WebCam in .Net? (I know they can be webcam specific, I am willing to buy a new webcam if it means better results). I want to write a desktop application that will take video from a webcam and store it in MPEG4 formats (DivX, Xvid, etc...). I would also like to access bitmap stills from the device so I can do image comparison between frames. I have tried various libraries, and none have really been a great fit (some have performance issues (very inconsistent framerates), some have image quality limitations, some just crash out for seemingly no reason. I want to get high quality video (as high as I can get) and a decent framerate. My webcam is more than up to the job and I was hoping that there would be a nice Managed .Net library around that would help my cause. Are webcam APIs all just incredibly bad?

  • Is it possible to reference a file stored in Isolated Storage by its URI?

    - by Joel
    Using this previous question as motivation, I would like to temporarily store images and videos in Isolated Storage. My application (written in WPF/C#) will allow a user to review these temporarily stored items by viewing their contents in a MediaElement. I was hoping to set the MediaElement's Source Property to a video or image's URI stored in IsolatedStorage but I cannot figure out how to dynamically create a URI since it doesn't appear to be naively supported by IsolatedStorage. Any help would be greatly appreciated - thank you in advance! Update - 1/21/09 After battling the issue for a day, I concluded that the Isolated Storage approach is not practical for storing large video files that need to be referenced by a Uri.

  • iPhone SDK: Downloading large files from a server into the app bundle.

    - by Jessica
    Hi, I am building an app that plays multiple video files, But I would like to know How do you download a video file (100mb - 300mb) from a server into the application's bundle so it can later be locally referred to in code? The reason I want this type of a set up in my app is that I don't want the app binary to be made unnecessarily large due to including videos some users may not want. Also does this violate any of apple's terms? Also would it be simple to implement a progress view with this kind of set up and if so how? Any help is appreciated.

  • Redirect window of command line tool to your app (Windows)

    - by dribler
    Hello, is there a way (on Windows XP+) to redirect the output of a window created by a process created with e.g. CreateProcess to a window of your own program? I'd like to make a nicer GUI for ffplay.exe which is an open source video player. It is a command line tool, which opens a simple window in which it plays back the video. Can I "capture" this window and display the output in my own program somehow? Thanks for any hints you can provide.

  • MPMoviePlayerController iPhone 3G & .mov file format

    - by Matt
    Just posting a question to the world... My app is currently setup to play video files. The app is setup to play .mov files and when tested on a 3GS, iPhone 4, and an iPad, it works great. But when playing on an iPhone 3G, the file does not play. Is this based on different compression standards that the 3G can't handle? I liked the .mov extension as it was compressed nicely to stream to the device. I have now converted the video files to .m4v so it will play on the 3G, but the file is now 3 times the size. Thanks in advance for any answers I get!!

  • MySQL COUNT() multiple columns

    - by liam
    Hello, I'm trying to fetch the most popular tags from all videos in my database (ignoring blank tags). I also need the 'flv' for each tag. I have this working as I want if each video has one tag: SELECT tag_1, flv, COUNT(tag_1) AS tagcount FROM videos WHERE NOT tag_1='' GROUP BY tag_1 ORDER BY tagcount DESC LIMIT 0, 10 However in my database, each video is allowed three tags - tag_1, tag_2 and tag_3. Is there a way to get the most popular tags reading from multiple columns? The record structure is: +-----------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | flv | varchar(150) | YES | | NULL | | | tag_1 | varchar(75) | YES | | NULL | | | tag_2 | varchar(75) | YES | | NULL | | | tag_3 | varchar(75) | YES | | NULL | | +-----------------+--------------+------+-----+---------+----------------+
