• Conversion of individual mp4 files to ts yields unexpected playback

  3 août 2021, par MorenoGentili

  I'm converting three mp4 files (h264, no audio, each with a duration of three seconds) to the mpeg-ts format like so.

  


  ffmpeg -i 1.mp4 -c copy 1.ts
ffmpeg -i 2.mp4 -c copy 2.ts
ffmpeg -i 3.mp4 -c copy 3.ts


  


  Please note : I can't combine the mp4 files beforehand. Each one has to be converted individually as shown above since they're being generated by a live recorder.

  


  Then, I manually created a .m3u8 manifest like this one, so I could play those 3 ts files in sequence :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-TARGETDURATION:3
#EXTINF:3,
1.ts
#EXTINF:3,
2.ts
#EXTINF:3,
3.ts
#EXT-X-ENDLIST


  


  When I run the ffplay index.m3u8 command :

  


  

  • 1.ts is played for three seconds as expected ;

  


  • 2.ts is played "for a split second" (maybe just a frame) ;

  


  • 3.ts is played for three seconds as expected.

  


  


  Can someone explain why 2.ts is shown for such a brief time ? When I run ffmpeg -i 2.ts, the output is correctly displaying a duration of three seconds.

  


  Input #0, mpegts, from '2.ts':
  Duration: 00:00:03.00, start: 1.480000, bitrate: 49 kb/s


  


  How can I change my mp4 -> ts conversion commands so that each file can play for their whole duration (i.e. three seconds each) ? I'd like to avoid reencoding if possible.

  


  Thank you, I'm adding a link to the three files and the manifest for completeness.

  


• automatically convert all video to mp4 h264 [on hold]

  23 août 2013, par Xiabili

  I am a debian user and I have a lot of videos (wmv, flv, mp4 ... more than 100gb) on my server.

  The problem is that the most of these videos are with mpeg4 and these codec is not supported by our Wowza server (basic License).

  That is way we want to convert all these videos into H264 format.

  So I need a script that converts videos recursively in the folders and if possible remove the old files after the converting.

  I need your experience ! Thanks a lot !
