• FFMPEG RTMP Streaming to Android　Exec

  4 octobre 2012, par user1653922

  I have done in Android using FFMPEG RTMP streaming

  As a practical matter, an error is output when the RTMP streaming with Android.

  "rtmp :/ / ~ / oflaDemo / test live = 1": No such file or directory

  Command execution in Android is as follows.

  String [] command = new String [] {"/ directory / ffmpeg", "-vn", "-re", "-i", "\" rtmp :/ / ~ / oflaDemo / test live = 1 \ "" , "-loglevel", "debug", "pipe: 1"};
  
  Process process = Runtime.getRuntime () exec (command, null);

  Successfully decoded the above command on a FFMPEG on Windows.

  I would like you to tell me if it is good How can Android Can I run the above command.

• Android mp4 Media File Won't play

  17 juillet 2014, par Liron

  I had the same problem as here which I thought was because the files (recorded on iOS) were encoded as .mov instead of .mp4.

  I then changed the encoding mechanism on my iOS app to encode them as mp4, and I’m still seeing the same problem.

  When I load the file with

  File videoFile = ...;
  
  videoView.setVideoPath(videoFile.getAbsolutePath());
  
  videoView.start();

  I get E/MediaPlayer(2069): error (1, -2147483648).

  When I load the file with the following (from the link above).

  Uri uri = Uri.parse(VideoProvider.CONTENT_URI_BASE + Uri.encode(videoFile.getAbsolutePath()));
  
  videoView.setVideoURL(url);
  
  videoView.start();

  I get this in logcat

  07-17 08:05:58.283: W/VideoView(2276): Unable to open content: content://com.companyname.VideoProvider.files.files/%2Fdata%2Fdata%2Fcom.companyname.myappname%2Fcache%2FiX0mXVPxih.mp4
  
  07-17 08:05:58.283: W/VideoView(2276): java.io.IOException: setDataSource failed.: status=0x80000000

  ffmpeg tells me the following about the media file :

  ffmpeg -i media.mp4

  Any idea why this file might be failing to load ?

  EDIT : Seems that this is mostly an issue when running in the emulator, but on a device I seem to have succeeded it getting it to work if I use a SurfaceView and MediaPlayer instead of VideoView.

• FFmpeg lagging issue in android

  5 septembre 2012, par Balwant Kumar Singh

  I'm using FFmpeg using dolphin player. I'm getting video lagging issue and also Audio/Video synch issue for big files.

  Is there any solution to get rid of it ? I'm pretty new in this and don't have the knowledge FFmpeg code.

  I've gone through this FFmpeg tutorial site, http://dranger.com/ffmpeg/ffmpeg.html.

  With this I can understand about a little about implementing internal audio/video clock.
  I'm not able to understand, in which part of FFmpeg I should do alteration for solving this problem.

  Kindly reply with a solution...
