• android ffmpeg concatenate multiple m4a files

  19 janvier 2017, par margie

  I need help in concatenating audio files in android using ffmpeg

  My source of audio files is from recording result (container .m4a, encoder aac).
  When I concat them using ffmpeg, the result file length(duration) is only of the 1st file.

  ie. FileA length = 1:00, FileB length = 0:14. Expected FileResult length = 1:14, but actual result is 1:00).

  I also tried the command I used in desktop ffmpeg and it give the same result.

  This is my command :

   [-i, 
  
  concat:storage/emulated/0/Music/Recordings/REC_20170119_162023.m4a|/storage/emulated/0/Music/Recordings/REC_20170119_162042.m4a, 
  
  -c, 
  
  copy, 
  
  /storage/emulated/0/Music/Recordings/REC_20170119_162047.m4a]

  and the ffmpeg result is :

• ffmpeg : StreamNotFound error

  27 janvier 2017, par KMG

  I’m using Adobe Media server and push streams to this server using FMLE.

  My stream name : appvideo

  When I tried to pull the video from the server using ffmpeg/ffplay, I’m not getting "stream not found error". Whereas rtmpdump can stream the video.

  After I see the logs, all the ffmpeg request logs have a stream name with extension .flv like [appvideo.flv]. But rtmpdump not append this extension [ like appvideo].

  FFMpeg/ffplay log in Media server :

  play    stream  2017-01-27  02:26:17    GMT appvideo    10.11.12.202    32715   11  17  _defaultRoot_   _defaultVHost_  live    _definst_   0   404 183.82.250.50   rtmp    -   rtmp://10.11.12.202:443/live    rtmp://10.11.12.202:443/live    -   --  4702122229742256497 3135    3631    normal  appvideo    -   -   rtmp://10.11.12.202:443/live/appvideo.flv   rtmp://10.11.12.202:443/live/appvideo.flv   -   flv 0   0.000000    0   -   0   0   -   -   -   -   1   -   --  -   -   -   -   -   -   -1  -1.000000   -

  Not sure why request append .flv extension at last like this : rtmp ://10.11.12.202:443/live/appvideo.flv
