Hi Christian,
I have tested this patch but then the displayed video is garbage (mostly
white and sometimes just garbage). It also stall the nouveau driver which
requires to reboot but I guess this is another issue.
I tested with:
GST_GL_WINDOW=x11 GST_GL_PLATFORM=egl GST_GL_API=gles2 GST_DEBUG=2
LIBVA_DRIVER_NAME=gallium gst-launch-1.0 filesrc location=simpson.mp4 !
qtdemux ! vaapidecodebin ! glimagesink
(to test that you need my gstreamer-vaapi and gstgl branches on my github
but I would not waste time to try them since they should be merged upstream
at some point)
Also note that in this pipeline, HW decoding is done with nouveau driver
and rendering is done with intel. dmabuf in between.
Maybe the idea of the patch is good but something is still wrong.
I can test any update if it helps.
Cheers
Julien
