• Android ExoPlayer stream mp3 over HTTP

  8 juillet 2016, par kevintcoughlin

  I’m trying to get a grasp on the new ExoPlayer library introduced this year at Google I/O 2014 so that I can incorporate it into my application.

  I’m attempting to stream an mp3 over HTTP, but so far have been unsuccessful. I’m not sure if it’s possible, but I’m trying to accomplish this without extending any of the base Source/Sample classes. My code is as follows :

  In my Activity

  SampleSource s = new FrameworkSampleSource(this, Uri.parse("http://traffic.libsyn.com/joeroganexp/p518.mp3"), null, 1);
  
  
  
  // Since I only have 1 audio renderer
  
  ExoPlayer player = ExoPlayer.Factory.newInstance(1);
  
  
  
  MediaCodecAudioTrackRenderer audioRenderer = new MediaCodecAudioTrackRenderer(s);
  
  player.prepare(audioRenderer);
  
  player.setPlayWhenReady(true);

  To my untrained eye it seems like I can get the TrackInfo correctly, but am having a problem reading the data over HTTP. It also seems that how the framework sniffs the mimetype is failing even though I do receive type ’audio/mpeg’.

  Again, I appreciate any direction I receive. I realize that these APIs are very new.

• FFMpeg kills itself when restreaming http to rtmp

  22 novembre 2019, par dust19992

  We are trying to restream few stations to our Emby server (alternative to plex), but always when we start the command as provided by many cast-software it runs for some time and then it dies.

  Here is our command :

  Our server is WOWZA media server, and we have been looking for the problem for some time now, but without any success, so we hope you guys can help us figure it out, we are trying to copy the live video as it is, and we do not want to change the encoding, or anything else, but if necessary then it has to be encoded.
  
  
  
  I have not much experience in ffmpeg but we have been using VMIX that uses ffmpeg and it's running smooth there to the server without dying, so there has to be a way to run that with the ffmpeg standalone. 
  
  
  
  Here is the WOWZA restream manual: https://www.wowza.com/docs/how-to-restream-using-ffmpeg-with-wowza-streaming-engine
  
  
  
  Thanks.

• Including the switch "-hls_flags temp_files" while encoding to HLS does nothing

  24 juillet 2019, par cloudhorn

  I’m trying to disable access to video segment files while they are still being converted. This is to stop my web-page from loading the unfinished segments.

  One solution that appeals to me is using the ’-hls_flags temp_files’ option that (according to the docs) initiates segments with the name ’filename.tmp’, and renames them only once the segment is complete. This is opposed to the standard ffmpeg behaviour where unfinished segments have the same name as the completed ones.

  Problem is I can’t get ’-hls_flags temp_files’ to do anything. Converting a video with :

  ffmpeg -i aerial.mov -g 60 -keyint_min 60 -sc_threshold 0 -f HLF -hls_time 2 -hls_list_size 0 -hls_flags temp_file aerial.m3u8

  produces the exact same output as running the same command line without ’-hls_flags temp_file’. Does anyone have experience using ’temp_file’ ?

  EDIT : Issue was solved by getting a static git build of ffmpeg, instead of the latest (4.1.1) release build I had, as pointed out by user Gyan :

  Micro version of release should be ignored. git master is branched off for minor and major bumps. Minor upgrades only have security fixes for the most part. Get a static git build. Get one from the left column at johnvansickle.com/ffmpeg
