Victor,
Found some time to pick up my investigation on vaapi on v4l, using
bootlin's vaapi backend.
I am using gst-build to get latest sources, and set the env variables
as you suggested.
The vaapi backend is properly detected:
# gst-inspect-1.0 vaapi
Plugin Details:
Name vaapi
Description VA-API based elements
Filename
/root/gst-build/build/subprojects/gstreamer-vaapi/gst/vaapi/libgstvaapi.so
Version 1.15.0.1
License LGPL
Source module gstreamer-vaapi
Binary package gstreamer-vaapi
Origin URL
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer
vaapimpeg2dec: VA-API MPEG2 decoder
vaapipostproc: VA-API video postprocessing
vaapidecodebin: VA-API Decode Bin
vaapisink: VA-API sink
4 features:
+-- 4 elements
The pipeline I am trying now is (see full log below):
GST_DEBUG=vaapi*:4 gst-launch-1.0 filesrc
location=~/big_buck_bunny_480p_MPEG2_MP2_25fps_1800K.MPG ! mpegpsdemux
! vaapimpeg2dec ! video/x-raw,width=854,height=480 ! kmssink
Now, my question is: is it possible to connect a vaapi decoder to a
non-vaapi sink? Judging from this traces:
0:00:01.230428590 32630 0x555350 INFO vaapidecode
gstvaapipluginbase.c:959:gst_vaapi_plugin_base_decide_allocation:<vaapidecode_mpeg2-0>
ignoring non-VAAPI pool: <kmsbufferpool1>
0:00:01.270321791 32630 0x555350 ERROR vaapi

0:00:01.270796060 32630 0x555350 ERROR default
gstvaapisurface_drm.c:54:gst_vaapi_surface_get_drm_buf_handle: failed
to allocate export buffer proxy
I think not. So, I need to add proper support for a vaapisink DRM
display, right?
