gstreamer-vaapi no VA Surface available mpeg2 streams

[arnaud tonda]

Dear all,

firstly this is my work environment :

Asus AT3 with nvidia GT218 Chipset.
latest stable version of gstreamer base and plugins (good, bad)
latest git version of vdpau-va-drivers
latest git version of libva
latest git version of gstreamer-vaapi


I actually try to play some tv records that are mpegts streams with mpeg2
video inside.
to get benefits of hardware acceleration, i would get working
gstreamer-vaapi.

after compiling and installing gstreamer-vaapi i can play some h264 streams
fluently with vaapidecode and vaapisink inside a playbin2 element.

the problem i have, seems to occurs only with mpegts streams.

the pipeline go in PLAYING state, the audio play fine, but i have only the
first video frame.

after adding some debug traces with this command line :

GST_DEBUG=vaapi:5,vaapidecode:5 gst-launch -v playbin2
uri=file:///tv/bfm_business.ts

it appears some errors on vaapidecode element :

Is there someone who can explain me what means that there is no VA surface
available?

maybe i have forgotten something to do.

i don't understand where can be the problem.

here some VAinfo if needed :

libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/nvidia_drv_video.so
libva: va_openDriver() returns 0
