I want to extract video track's codec string from a webm video in javascript and pass it to browser's VideoDecoder configure method to decode this video.
For example: If the codec of video track in webm video is V_VP9 in the EBML formatted file but how do I extract the whole string like this 'vp09.01.20.08.01'.
So to summarise I want a codec string of video track from the webm video file in javascript.
I tried setting only 'vp09' into VideoDecoder configure but this is giving error as codec string is ambiguous.
