Well, that's the first I've heard about it being a experimental POC. 
Nonetheless, it's a bug and can be further triaged as you see fit.  LibVA h.264
capture is about to be released as a feature in Weston.  IRCC, using the
feature causes a GPU hang too, only on Sandybridge, and likely rules out Weston
itself.  So libva or the libva intel-driver seems like the next logical
component to investigate/assign until evidence shows otherwise.  Who knows,
maybe it's a kernel-level bug like some of the decode hangs we've encountered
(Brian did rule out RC6)??

Yeh, seems like a logical [co-]owner since Ander enabled the feature in Weston.
 Not sure if there is another "vehicle" (apart from Weston) to test the libva
h.264 encoding pipeline.  If there is, then that might be a good place to look
at the bug.
