Screen shot of YouTube video in Chromium, artifacts
I am attempting to play H.264 video in Chromium, using a fork of the current
beta (v71) that has a VAAPI patch applied. When playing the following video:
<a href="https://www.youtube.com/watch?v=oiSn2JuDQSc">https://www.youtube.com/watch?v=oiSn2JuDQSc</a>
I get the resulting video output, attached.
Using:
Description: Ubuntu 18.10
Release: 18.10
chromium-browser 71.0.3578.62-0ubuntu1~ppa1~18.10.1
mesa-va-drivers 19.0~git1812040730.bacf84~oibaf~c
It should be possible to follow those to the patches used, but I don't think
that the Chromium patch is responsible for "misusing" VA-API, so much as the
radeonsi VA-API driver being broken in some way.
The artifact simply goes away if I disable h264ify, since it switches to VP9,
and thus software decoding.</pre>
