  • Naudio,how to tell playback is completed

    - by Du Sijun
    I am using Naudio lib to write a simple win form audio recorder/player. My problem is how can I tell the playback is completed? I need to close the wave stream after that. I knew there is a PlaybackStopped event listed below: wfr = new NAudio.Wave.WaveFileReader(this.outputFilename); audioOutput = new DirectSoundOut(); WaveChannel32 wc = new NAudio.Wave.WaveChannel32(wfr); audioOutput.Init(wc); audioOutput.PlaybackStopped += new EventHandler<StoppedEventArgs>(audioOutput_PlaybackStopped); audioOutput.Play(); But this PlaybackStopped event seems can only be triggered by calling audioOutput.stop(), do anyone know how to determine if playback is complected? Thanks in advance C#,windows form,Naudio,windows 7,64bits

  • Gapless (looping) audio playback with DirectX in C#

    - by horsedrowner
    I'm currently using the following code (C#): private static void PlayLoop(string filename) { Audio player = new Audio(filename); player.Play(); while (player.Playing) { if (player.CurrentPosition >= player.Duration) { player.SeekCurrentPosition(0, SeekPositionFlags.AbsolutePositioning); } System.Threading.Thread.Sleep(100); } } This code works, and the file I'm playing is looping. But, obviously, there is a small gap between each playback. I tried reducing the Thread.Sleep it to 10 or 5, but the gap remains. I also tried removing it completely, but then the CPU usage raises to 100% and there's still a small gap. Is there any (simple) way to make playback in DirectX gapless? It's not a big deal since it's only a personal project, but if I'm doing something foolish or otherwise completely wrong, I'd love to know. Thanks in advance.

  • Java stop MIDI playback

    - by user456268
    Hi I have java application which plays midi messages from sequence. I'm doing this using jfugue library. the problem is when I'm tryingto stop playback with stop button (which call sequencer.stop() and sequencer.close()) the last played note is sound all of rest time, and I can't stop it. So I'm asking about solution about stopping all audio and MIDI too! sound playback from java application. Notice: If you want propose just mute volume, you need to know that I want end-use will be able to press play button again and hear the sound again, so muting volumr will be not a solution, or explain please. Thank you!

  • Record/Playback with AudioQueue on iPhone

    - by Biranchi
    Hi, I am currently using Audio Queues on the iPhone to record and playback audio. What I would like to be able to do is to record some audio, allow the user to pause the record queue, and to seek back and forward through the audio to select a position from where they can start recording from again. I have got over the seeking issue by making the playback AudioQueueBuffer sizes small enough so that the play audio queue callback happens at a rate that allows the user to use a slider control to hear the audio as they adjust the slider back and forth. I think I can achieve the recording at a new position by setting the inStartingPacket parameter of the AudioFileWritePackets function that I call from the Audio Recording Queue callback. The trouble is this only inserts audio over the previously recorded audio. The file length obviously doesn't change so if the user were to go backwards and record less audio than before, the old audio still remains after the end of the newly recorded audio. Is there a way I can get the AudioFile to truncate at the point the user starts to insert the new audio, is there some other way I can remove the old audio starting at the insert position or is there a better way about going about this task? Thanks

  • No video playback when using home sharing on iTunes for Windows

    - by Diago
    I recently configured iTunes Home Sharing on my home network. My WHS server is the central library sharing both my Music and Video files. All my videos are encoded into H.264/MP4 format. All my machines are authorized and has access to Home Sharing. All my machines are running the latest version of iTunes 9. On my Snow Leopard machines iTunes happily plays the videos and music with no issues. On the Windows 7 machines however the play button fades for about 2 seconds when selecting a shared video and then nothing happens. The Windows machines are running the latest Community Codec Pack. Music sharing works perfectly on the Windows machines. When accessing the videos through the native WHS media connect sharing as well as through the file share I can play them perfectly on the Windows 7 machines. When adding the file to the iTunes library on the Windows 7 machine it also plays perfectly. Any advice, ideas or suggestions as to how to play the videos I have shared through Home Sharing on Windows 7?

  • DV-AVI in DivX Plus Player and VirtualDub - playback issue

    - by user714965
    I have an AVI-video which I had (digitally) transferred from a DV camera to my PC. The video contains errors at the beginning most likely because the DV tape was pretty old. When playing this video in the DivX Plus Player I get some picture artefacts and some high noise peaks of the sound. These stops after two seconds. When I'm playing this video in VirtualDub (where I want to cut it) I get the same picture artefacts. But the sound errors (those loud high peaks) lasts ten seconds. These sound errors are also contained in the cutted video. Why does the video have more errors when played in VirtualDub? I think because of different codecs which are used for decoding the video? How can I change the codec which VirtualDub uses for decoding? I have installed ffdshow for this but it seems that it is not used because I don't get the ffdshow icon in the taskbar when playing the video in VirtualDub. When playing in DivX Player Plus I get this icon.

  • Encoding video stream for playback on a vanilla Windows XP with mencoder

    - by Tamás
    I have a bunch of PNG files, generated from a script. They represent consecutive frames of a video sequence and I'd like to encode them into a single AVI file (or some other video format) using mencoder. What parameters should I use to ensure that the video can be viewed on a vanilla Windows XP using Windows Media Player with no extra codecs installed apart from the default ones? So far I've tried -ovc lavc -lavcopts vcodec=wmv2 and -ovc lavc -lavcopts vcodec=msmpeg4 with no success. (Background story: some of the people I'm collaborating with on a scientific project cannot install any codecs on their university computers without the help of the local sysadmins, who are of course not very willing to install anything. I'd like to ensure that they can also view the video files I am creating).

  • Stop playback of my voice when using mic during a call with twinkle voip

    - by ageis23
    Hi When I'm making voip calls with twinkle I can hear myself via the speakers. It's not like an echo you might get in empty room for example. While this is useful if you're trying to check if your mic is working, it's annoying when you're trying to have a conversion. Constantly trying to filter out your own voice. I'm using twinkle as my client. Is it my client or is it a setting on my ATA/ mic configuration?

  • Edubuntu video playback and apt-get

    - by asdasd
    They had installed some modified edubuntu's at school... So i have some questions about setting some things up: How we can play HD videos ? They are made for windows machines and are in .wmv format but we need to play them on our multimedia class but don't know how - which player, which codecs etc. How to edit properly the /etc/apt/sources file ? Anything we try to install via apt-get it just says that E:\ is not available. Please tell me which repositories to put in there so we could be able to install some tools. Where are usually viruses/trojans put in ubuntu ? I mean in which directories ? Because our computers are behaving really slow and we need to check for some malware manually - we are not even allowed to install any kind of AV software. So tell me the usual directories and places for hiding such files, how are they hiddem, how to recognize them etc. Any others nice tricks/tips that we need to know. Thank you very much in advance.

  • iTunes and Hulu Playback Choppy and Slow?

    - by Bart Silverstrim
    Specs: Windows XP, latest updates 1.7 ghz Pentium 4 1 gig ram DirectX 9.0c NVIDIA GeForce FX 5200 with 256 meg RAM OpenGL 2.1 The story: Okay, I had an older system laying around that I figured I would try turning into a mini-media system to connect to our TV. I put together a lot of older parts, got it into working order, etc. and hooked it up and voila'...slower, but usable system that displayed to the TV. It could run some things decently. I put in iTunes, it played video okay. Not great, but okay. Played Hulu and since we have a 1Mb download rate, the minimum for their site, there were some choppy moments when watching their shows, but I found that (sadly) changing resolution to 800x600 seemed to help with the issue when running full screen. I downloaded the application called Boxee and installed it. It wouldn't run; apparently the video card in the system supported OpenGL 1.2, and needed at least 1.4. I bought a cheap card, the 5200, with four times the memory in it and support for OpenGL 2.1. Installed, everything seemed fine. iTunes seemed to run fine, the video driver (PNY video card) came with OpenGL 2.1, and Boxee finally ran. I then upgraded to the latest drivers for the video card and ran the DirectX updater from MS. After that, the OpenGL Extension Viewer wouldn't run. It just stayed as an icon in the task bar. Also, any and all videos in iTunes stuttered and went out of sync horribly. Unwatchable. I tried watching Hulu video in Boxee, and it displayed video like it was a series of stills in a very bad powerpoint. Playing straightforward audio-only came through fine, no stutters no hiccups. I tried system restore to roll back updates to pre-directX updates (I thought that seemed to be the time that triggered the weird behavior), no joy. I tried uninstalling and reinstalling the video drivers. I installed updated audio drivers (ensoniq audiopci), nothing helped. I finally wiped the drive last night and tried reinstalling everything and restoring my iTunes content via an import from a backup. Fresh install, no updater on the video card or directx. the problem was still there although I haven't tested Hulu, the iTunes player is still stuttering like crazy if I play video, fine if I play audio. I know the processor isn't high in heft, but with one gig of RAM and the fact that it seemed to do okay before I thought that the problem must be software related. Has anyone else run into this sort of issue and have a solution other than "buy a new computer"? What specs seem to work with video at the low end for you? Right now the system is of little use other than keeping my music library and iTunes apps synced with my iPod.

  • Playback random section from multiple videos changing every 5 minutes

    - by brian
    I'm setting up the A/V for a holiday party this weekend and have an idea that I'm not sure how to implement. I have a bunch of Christmas movies (Christmas Vacation, A Christmas Story, It's a Wonderful Life, etc.) that I'd like to have running continuously at the party. The setup is a MacBook connected to a projector. I want this to be a background ambiance thing so it's going to be running silently. Since all of the movies are in the +1 hour range, instead of just playing them all through from beginning to end, I'd like to show small samples randomly and continuously. Ideally the way it would work is that every five minutes it would choose a random 5-minute sample from a random movie in the playlist/directory and display it. Once that clip is over, it should choose another clip and do some sort of fade/wipe to the chosen clip. I'm not sure where to start on this, beginning with what player I should use. Can VLC do something like this? MPlayer? If there's a player with an extensive scripting language (support for rand(), video length discovery, random video access). If so, I will probably be able to RTFM and get it working; it's just that I don't have time to backtrack from dead-ends so I'd like to start off on the right track. Any suggestions?

  • flash h264 mp4 playback pixelation

    - by ndmweb
    Working with converting/playing h264 mp4 videos in flash. I'm converting the video from various source file formats (mostly .mov & .mp4), to h264 mp4 using ffmpeg server side. All seems to be working just fine, except I'm getting a few reports of pixelation of the video when being viewed on windows machines. I've testing just about every browser I can think of on (XP/Vista/7) and could not reproduce. Here's a screenshot: http://i.imgur.com/IK5RV.jpg (sorry for the resolution, was in an email from the client, as I'm unable to reproduce.) Anyone else ever run into this issue? At this point it could be anything in my mind. It seems like an odd bug, and probably a codec issue, or somehow a 32/64-bit issue?

  • iPhone SDK: Change playback speed using core audio AVAudioPlayer

    - by Harkonian
    I'd like to be able to play back audio I've recorded using AVAudioRecorder @ 1.5x or 2.0x speed. I don't see anything in AVAudioPlayer that will support that. I'd appreciate some suggestions, with code if possible, on how to accomplish this with the iPhone 3.x SDK. I'm not overly concerned with lowering the pitch to compensate for increased playback speed, but being able to do so would be optimal.

  • Video playback with jQuery Mobile and Phonegap

    - by aritchie
    I'm fairly new to mobile apps, so am trying to knock up a simple video player using Phonegap and jQuery Mobile. The problem is, jQuery mobile appears to be blocking the video playback for some reason. To troubleshoot I stripped it right back to the following HTML, but get the same result, ie a black rectangle where the video should be, but no video playback or controls. <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="viewport" content="width=device-width,initial-scale=1"/> <link rel="stylesheet" type="text/css" href="css/index.css" /> <link rel="stylesheet" href="css/jquery.mobile-1.2.0.min.css" /> <script type="text/javascript" src="cordova-2.2.0.js"></script> <script type="text/javascript" src="js/index.js"></script> <script src="js/jquery-1.8.3.min.js"></script> <script src="js/jquery.mobile-1.2.0.js"></script> <title></title> </head> <body> <div> <video controls autoplay> <source src="video/video1.mp4" type="video/mp4" > </video> </div> </body> </html> If I remove the link to jquery.mobile-1.2.0.js the video shows up and plays, otherwise, just the black rectangle. I don't know jQuery mobile at all, but searching in the js for a reference to the video elements doesn't show up, so I've no idea what is blocking it. The code works fine in Chrome and Firefox. There are no console messages in Xcode. I also tried hooking up to http://debug.phonegap.com/ but this gave no error messages either. Any ideas??

  • Is there an easy way to read blu-rays on Windows?

    - by ereOn
    Some time ago, I bought my parents a computer dedicated to medias (mostly photographs and movies trough DLNA). My father asked me if he could read blu-ray on it, so I bought a blu-ray reader but I can't find a software to do the playback. I installed PowerDVD (a free version we got with a Blu-Ray) but it seems it now requires a (non-free) upgrade. Even if it were free, I hardly see my parent do the upgrade by themselves as they barely understand how computers work. I thought I would find a free software (something like VLC, but for blu-rays) but so far had no luck. Do you guys have a software to suggest that would solve my issues ? It should run on Windows Vista, shouldn't require an update every monday, or at least a free one. Thank you very much.

  • Dynamic Midi generation and playback on Android: Possible?

    - by Peterdk
    Strangely I find no support for Midi in Android. The only thing that comes close is the Jetplayer, but this only takes a existing .jet file. I want to dynamically generate a midi file with some intervals and play it. I even thought about just manually creating a .jet file with a tone and then transposing it with the jet player, but it limits the transposing to -12, +12. Which is not so good for me. There also is a ToneGenerator on Android, but it's limited to predefined tones with no way to transpose. Does someone know how to achieve midi generation and playback on Android?
