gstreamer crashes with gstreamer-vaapi installed
The issue is documented here.
The following error
(parole:4094): GStreamer-Base-CRITICAL **: 13:27:30.761: basetransform: second attempt to fixate caps returned invalid (NULL) caps on pad vaapipostproc0:sink
shows up with different front ends (parole in my case). It is reliably reproducible in Arch Linux
when gstreamer-vaapi
is installed with the video mentioned here; when gstreamer-vaapi is not installed the video plays but without hardware acceleration.
Hardware acceleration driver: intel-media-driver (Intel UHD Graphics 10710U, Comet Lake GT2)
