Description (last modified by shirsendu)

Hi,

I am trying to transcode in webm dash format using

ffmpeg \
 -f webm_dash_manifest -i audio.webm \
 -f webm_dash_manifest -i video-800p.webm \
 -f webm_dash_manifest -i video-1280p.webm \
 -f webm_dash_manifest -i video-1920p.webm \
 -c copy -map 0 -map 1 -map 2 -map 3 \
 -adaptation_sets "id=0,streams=0 id=1,streams=1,2,3" \
 -f webm_dash_manifest \
 manifest.mpd

codecs="av1" -> codecs="av01.0.01M.08.0.111.01.01.01.0"

then files starts playing normally

site note I got this codec name when I try to transcode using dash encoder in ffmpeg not the webm_dash_manifest encoder

also bitstreamSwitching in video is false by default where it should be true for a video
