The gallium driver has a h265 decode module for libomxil-bella=
gio, but not for
https://github.co=
m/tizonia/tizonia-openmax-il implementation.
It's in /gallium/state_trackers/omx
https://github.com/freedesktop/mesa=
/blob/master/src/gallium/state_trackers/omx/bellagio/vid_dec_h265.c
tizonia includes EGL support so maybe it would be better to add the H265
encode/decode support to that because libomxil-beligago hasn't been updated
upstream since 2012.
Now I've checked with the official AMD Radeon (amdgpu) drivers 18.10 and th=
eir
bundled /etc/xdg/gstomx.conf doesn't have the hevc video decoder enabled by
default (through the configuration file), though I haven't checked yet if i=
t's
enabled in the code to make this a proper "GPL" source code reque=
st.
The patches are probably already floating AMD, OMX HEVC support has found i=
t's
way into mesa mesa but to the libraries that use it.
Can one use omx HEVC decode in the mesa state tracker without AMD's patch to
libomxil-bellago? Can you please release it?

The hevc decode support added a 6 months ago (1.14.0) to gst-plugins-omx is=
for
a different openmax implementation:
