This particular hang looks like a hardware/driver bug. I've easily reproduced it on my machine now (first video from youtube, at 1:42). However it only got frozen for couple of seconds. Then I had this at dmesg:

[44023.519511] [drm:i915_set_reset_status] *ERROR* bsd ring hung flushing bo (0x1786d000 ctx 0) at 0x1bda4

libvdpau-va-gl is just a wrapper between APIs. In turn, VA-API driver is another wrapper, which converts VA-API calls to batches of commands and sends them to GPU. Wrong data can lock GPU.

I'll dig deeper into the issue, but it's unlikely it could be solved in user-mode code. Thanks for reporting.

It works well in native players with vaapi decoding, but fails in flash

Thank you for the test case. It reproduces on my machine too.
