  • ffmpeg live dash content is not being played after loop

    27 octobre 2022, par Przemo

    I have problem with audio and video presence after looping the files used in live dash streaming.
    
I am using following ffmpeg command :

    


    ffmpeg -re -fflags +genpts -stream_loop -1 
-i H265_2160p60_VBR_30Mbps_OTT.mp4 
-i H265_1440p60_VBR_20Mbps_OTT.mp4 
-i H265_1080p60_VBR_15Mbps_OTT.mp4 
-i H265_900p60_VBR_10Mbps_OTT.mp4 
-i H265_720p60_VBR_5Mbps_OTT.mp4 
-i H265_576p60_VBR_1Mbps_OTT.mp4 
-map 0 -map 1 -map 2 -map 3 -map 4 -map 5 
-c copy 
-streaming 1 -use_timeline 1 -use_template 1 -window_size 30 -remove_at_exit 1 -segment_wrap 30 
-adaptation_sets "id=0,seg_duration=2,streams=v id=1,seg_duration=2,streams=a" 
-init_seg_name 'live-$RepresentationID$-init.m4s' -media_seg_name 'live-$RepresentationID$-$Time$.m4s' 
-f dash video/out.mpd


    


    Main problem is that the A/V is present until the streams loop (every stream has the same length).
    
FFmpeg is still processing the files but the client is not able to play the content anymore.

    


    Additional problem is that the dash.js is not able to play the content due to dynamic manifest. Is there an option in ffmpeg to change type on manifest ?

    avformat/rtpdec : Add support for 24 bit RTSP audio playback

    When ffplay is used to play from the RTSP URL that serves 24 bit audio
    
content, ffplay fails to recognize the audio codec format. The attached
    
patch adds support for playing 24 bit audio content over RTSP by
    
defining a dynamic payload handler for "L24".

  • avformat/matroskaenc : Improve writing Projection

    1er janvier 2020, par Andreas Rheinhardt
    avformat/matroskaenc : Improve writing Projection

    The Matroska Projection master element has such a small maximum length
    
that it can always be written with a length field of length one.
    
So it is unnecessary to first write the element into a dynamic buffer to
    
get the accurate length in order not to waste bytes on the length field.
