NOTES : sources are cams streamed first to hls/m3u8. -t 10 only for testing purposes.


The problem is variable output fps= 12 (sometimes 2, 5, 10, maybe 13) where I expect 30. Machine is 10 times greater (encode uses up to 5% cpu).


Im trying adding -re, -r 30, -r 15 to sources, convert sources via stream_filter (,fps=30), vsync (old versions of ffmpeg), wallclock time, etc. and reading stackoverflow of course. And... nothing.


Where is the problem ?

Do I need multiple video files in different resolutions to use MPEG DASH ?
2 février 2023, par Gentil AlysonI'm trying to use Django REST Framework to serve .mpd files. When the user uploads a video, the server creates the MPD and the chunk files. However, I can't seem to able to make it work. I've tried using python-ffmpeg-video-streaming, but the client which is using dash.js to play the video will get only one bitrate (480p). I've also tried running this command
'ffmpeg -i {self.file.path} -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -var_stream_map "v:0,name:800k v:1,name:300k" -f dash -dash_segment_type mp4 -single_file 1 {file_dir}/dash.mpd'usingos.systemfrom Python, but then the player gets stuck at buffering.
