• avformat/hlsenc : fix handling of delete_segments when %v is present

  11 avril 2018, par Bela Bodecs

  avformat/hlsenc : fix handling of delete_segments when %v is present
  When var_stream_map option is used, %v must appear either in segment
  
  name template or in the directory path. This latter case currently is
  
  not handled and delete_segments flag of hls_flags is broken now. This
  
  patch fix this. The root cause of the bug was that HLSSegment struct
  
  only stores the final filename part, but not the final directory path.
  
  Most of the cases, final path info is unneded, It only necessary when
  
  you want to delete old segments (e.g in case of live streaming).
  
  Without variant streams it was unnecessary to store the final directory
  
  path, because all segment were stored into the same directory. But
  
  introducing %v in directory names either require to store the final
  
  directory path into HLSSegment or associate segments with their variant
  
  streams to be able deleting them later. I have choosen the second
  
  solution and introduced a variant index data member into the segment
  
  struct.

• Joining three videos with FFMpeg [duplicate]

  4 novembre 2016, par M. Saez

  This question is an exact duplicate of :

  • FFmpeg concatenation, no Audio in Final Output
    
    1 answer
    

  I’m trying to merge/join three mp4 videos with ffmpeg ; the first one is a 5 seconds intro without an audio track, then it is the main video and at the end there is a 6 seconds mp4 video also without an audio track.

  All videos are encoded with exactly the same settings, so far i’m trying the concat option and i can join them just fine, the problem is the final video doesn’t have the audio track from the main video.

  This is the command i’m using :

  ffmpeg -f concat -i mylist.txt -c copy output.mp4

  Needless to say, the final video must respect the first 5 seconds without audio and the last 6 seconds.

  Any idea ?, if i prefer something where i don’t need to reencode at all, but if i must, i don’t really mind.

  Thanks !

• Flutter ffmpeg_kit_flutter_full_gpl-6.0.3 PluginRegistry.Registrar flutter version 3.29

  30 avril, par Lisa

  I am using ffmpeg_kit_flutter_full_gpl-6.0.3 for flutter version 3.27 but when upgrading to flutter 3.29, with android, there is an error PluginRegistry.Registrar registrar. Is there any solution to replace the current ffmpeg_kit_flutter_full_gpl because I see this library was updated 17 months ago
