• avformat/{isom,mov,movenc} : add support for CMAF DASH roles

  15 juillet 2021, par Jan Ekström

  avformat/isom,mov,movenc : add support for CMAF DASH roles
  This information is coded in a standard MP4 KindBox and utilizes the
  
  scheme and values as per the DASH role scheme defined in MPEG-DASH.
  
  Other schemes are technically allowed, but where multiple schemes
  
  define the same concepts, the DASH scheme should be utilized.
  Such flagging is additionally utilized by the DASH-IF CMAF ingest
  
  specification, enabling an encoder to inform the following component
  
  of the roles of the incoming media streams.
  A test is added for this functionality in a similar manner to the
  
  matroska test.

• Converting images to video in Android using FFmpeg

  28 février 2024, par sneha Latha

  val cm = "-f image2 -i \"$imagesFolder/JPEG_08%d_06%d_.jpg\" -vcodec mpeg4 -b 800k output.mp4"


  


  this command is not able to .convert the images into video my images are in the format below :
