Adding a comment to indicate that this is a problem with the 10bpc support which is enabled in Radeon graphics. I am unsure if it is enabled in Intel's drivers, so that would explain why it does not occur there. Either VA-API is outputting wrong, the client library is outputting wrong, or all the player applications are wrong. Something appears to be matching the buffers to each other without a conversion, simply because both RGBA32 and RGBA10-10-10-2 have the same number of bytes per pixel, but clearly completely different structure.
A workaround is to add the following to the //driconf/device section of /etc/drirc: <application name="Default"> <option name="allow_rgb10_configs" value="false"/> </application> Clearly, this workaround should not be the only way, since someone in the processing chain clearly wants 10bpc support, and some applications can benefit from it, somehow. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1767312 Title: [radeon] Totem with gstreamer1.0-vaapi and Xorg: wrong color on H264 videos Status in gstreamer-vaapi package in Ubuntu: Confirmed Status in mesa package in Ubuntu: Confirmed Bug description: Ii've found a bug on Ubuntu 18.04 (other distros, as fedora 27, debian stable, debian testing) aren't affected).
