• I have an MJPEG file decoded with the Intel® IPP JPEG encoder [8.1.42291], how can I convert it to MP4 using ffmpeg ? [closed]

  8 mars 2024, par Renan Aragão

  When trying to convert the MJPEG file with ffmpeg, it gives the following error : Output file #0 does not contain any stream.

  


  This is the complete output :

• avformat/rcwtdec : add RCWT Closed Captions demuxer

  2 avril 2024, par Marth64

  avformat/rcwtdec : add RCWT Closed Captions demuxer
  RCWT (Raw Captions With Time) is a format native to ccextractor,
  
  a commonly used OSS tool for processing 608/708 Closed Captions (CC).
  
  RCWT can be used to archive the original extracted CC bitstream.
  
  The muxer was added in January 2024. In this commit, add the demuxer.
  One can now demux RCWT files for rendering in ccaption_dec or interop
  
  with ccextractor (which produces RCWT). Using the muxer/demuxer combo,
  
  the CC bits can be kept for processing or rendering with either tool.
  
  This can be an effective way to backup an original CC stream, including
  
  format extensions like EIA-708 and overall original presentation.
