  • How to not add AdaptationSet for audio if audio stream is not present in input file

    13 juin 2019, par Saurabh

    I am using ffmpeg-dash to create mpd files. I am using following command to generate the same :

    ffmpeg -i input/video.mov \
    
        -map 0:v:0 -map 0:v:0 -map 0:v:0 -map 0:a\?:0 \
    
        -b:v:0 350k -c:v:0 libx264 -filter:v:0 "scale=320:-1" \
    
        -b:v:1 1000k -c:v:1 libx264 -filter:v:1 "scale=640:-1" \
    
        -b:v:2 3000k -c:v:2 libx264 -filter:v:2 "scale=1280:-1" \
    
        -use_timeline 1 -use_template 1 -window_size 6  -adaptation_sets "id=0,streams=v id=1,streams=a"  \
    
        -seg_duration 2 -threads 16 -hls_playlist true -f dash output/ffmpeg/output.mpd

    This works with video which has audio streams, but for the case there is no audio stream in the video file, I get empty entry for audio in mpd files like following, which is not valid and fails while playing in Exo Player in Android.

    <adaptationset contenttype="audio" segmentalignment="true" bitstreamswitching="true">
    
</adaptationset>

    I tried adding ? in option adaptation_sets like : id=0,streams=v id=1,streams=a?, however that also adds above line.

    One solution is to run different commands for different videos by first checking whether there is audio stream or not, but would be better if there is some option which add audio adaptationSet only if audio stream is present in the input file.

  • avformat/mov : Enable stream parsing for VP9.

    avformat/mov : Enable stream parsing for VP9.

    MP4 media containing VP9 using superframes (such as
    
https://github.com/Netflix/vp9-dash/raw/master/DASH-Samples/Fountain_2997_0560kbps_640x480_4x3PAR.ivf_DashUnencrypted.ismv)
    
does not decode correctly with the built-in VP9 decoder because
    
superframes are passed to the decoder whole rather than split into
    
individual frames.
