How to consume VAAPI VASurface in appsink

[Galoppo, Nico]

Thank you - I just tried on a vanilla ubuntu 18.04 box. This one does support DMABuf. 

Now the following pipeline runs: 

gst-launch-1.0 -v souphttpsrc location=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm ! matroskademux ! vaapidecodebin ! "video/x-raw(memory:DMABuf)" ! glimagesink

However, the output is scrambled. Looks like wrong image frame metadata is passed, perhaps incorrect stride. 

The following pipeline runs correctly (not buggy), but since I'm not using a capsfilter, it's going through video/x-raw(memory:VASurface) at the glimagesink. 

gst-launch-1.0 -v souphttpsrc location=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm ! matroskademux ! vaapidecodebin ! glimagesink

That's too old. Update at least to GStreamer 1.12, or 1.14
