Hello,
sorry for the late reply, I had to take a break from the project.
The intel-media-va-driver fixed the
"gstvaapifilter.c:1373:gst_vaapi_filter_set_property:<vaapifilter0>
VA" PRoblem.
But I still have the problem that my pipeline does not work.

It seems that vapostproc can't convert from
video/x-raw(memory:DMABuf), format=BGRx to
to video/x-raw(memory:DMABuf), format=NV12 which is needed for
vah264enc. Or do I have a mistake somewhere else?
Thanks in advance and Greetings
Michael
