• Use FFmpeg to create MPEG-DASH files

  2 juillet, par angel_30

  I know using ffmpeg, we can create MPEG-DASH ready files, including the segments and the .mpd manifest file. For instance, I'm trying this command which works :

  


  ffmpeg -re -i .\video-h264.mkv -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline -profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 -b_strategy 0 -ar:a:1 22050 -use_timeline 1 -use_template 1 -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" -f dash out.mpd


  


  But I don't want to segment the video- so a simpler version where we have multiple versions of the whole video, no chunks. Does MPEG-DASH allow it ? If so, how can I use ffmpeg to do it without creating the chunks ?

  


• Applying video filters on MPEG Dash segments

  5 décembre 2019, par michalSolarz

  I know that it will probably require recreating whole MPEG Dash stream but I’m curious if is it possible to apply a drawtext video filter on existing Dash segments ? I I’ve managed to merge segments with init MP4 and apply that filter on it but I’ve no idea how and if it is possible to recreate MP4 segment similar to input one, fragmented and with only media data as input one ?
