Hey Victor,
The above didn't work, but tracing with some debugging levels I found this:
0:00:00.060866458 1435 0x22788600 ERROR default
gstvaapi.c:254:plugin_init: Cannot create a VA display
Which seems to be the reason why is not working. So I guess the next
step is look at my backend
and libva and see why it refuses to create the display.
Two things I am wondering are:
* Is there any "easy" way to build and use the master branch? I'm
using Buildroot to generate
this rootfs. AFAICS, I will have to build gstreamer (and all the
plugins to use master too), and there
is no way to use 1.14.2 for everything and master branch for vaapi.
* Any easy way to turn on libva messages?
Thanks,
