• FFMPEG Concat protocol Error : Found duplicated MOOV Atom. Skipped it

  11 septembre 2020, par user3541092

  I'm concatenating mp3 files into a single m4a.

  



  To save time, I'm doing the mp3 to m4a conversion first (multi-threaded) and then concatenating the output files (m4a) into a single m4a file.

  



  The concat works when I do the conversion (mp3 -> m4a) and cancat in one swoop. But it takes forever to run.

  



  Example :

  



  ffmpeg -i "concat:001.mp3|002.mp3|003.mp3" -codec:a aac -c copy output.m4a


  



  
If I take those same mp3 files and convert them to m4a in parallel and then concat, I can save myself a significant amount time.

  



  The problem is if I run the concat command on the converted m4a files

  



  Example cmd :

  



  ffmpeg -i "concat:001.m4a|002.m4a|003.m4a" -c copy output.m4a


  



  I getting the following error :

  



  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 000000000052f680] Found duplicated MOOV
 Atom. Skipped it

  


  



  
UPDATE : Ouput when concatenating m4a files (two track example) :

  



  C:\_ffmpeg>ffmpeg -i "concat:001.m4a|002.m4a" -c copy output.m4a

• hls.js starting a beginning with ANDROID mobile (chrome, webview also) and not live *** but works very nice in deskto, ios .. hls.js 1.0.0 2021-04-01

  27 avril 2021, par Jintor

  I'm streaming a .m3u8 with the latest hls.js 1.0.0 (not rc) but version of 2021-04-01...

  


  example : the stream began at 5pm, and now it's 5:15 pm...

  


  the stream start at live point in almost all browsers

  


  The pattern I see here : ALL browsers in android (tested in Android 10) won't start at live point, only at 0...

  


  I did all the tests
