Summary of the bug: The dash muxer will produce a manifest with a codecs
line having a "00" value in the bit depth section when using the vp9_vaapi
encoder. For ex. "vp09.00.21.00" (third value, after 21). This causes the
DASH playlist to be rejected for playback by Firefox and Chrome. Using
libvpx with the same muxer settings and such yields "vp09.00.21.08"
correctly. Spec says valid values for the bit depth are 08, 10, 12.
How to reproduce:
Generate a dash manifest with the dash muxer while passing a vp9_vaapi
encoded video stream to it. Observe the codecs string in the manifest mpd
file to see the bit depth line. Problem reproduced on master as of
2020-11-23.
