Bug ID: 92570
Summary: 10 bit h264 OMX UVD decode outputs NV12
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Other
Assignee: mesa-dev@lists.freedesktop.org
Reporter: adf.li...@gmail.com
QA Contact: mesa-dev@lists.freedesktop.org
No idea if this a Mesa OMX issue or UVD or gstreamer -
GPU is R9 285 Tonga.
In theory this should be able to h/w decode 10 bit h264 - and the h/w does seem
to process it.
The problem is that something is assuming/expecting/indicating that the output
is NV12, so the output is corrupted.
Here's a snip of a debug output from doing -
