Details

Looping sound, stuck keyboard and everything.

This is *not* reproducible with every MPEG2 but hit me on various dvb-t streams (while others play fine), h264 doesn't seem to be affected.
Downgrading to 381.22-8 resolves the bug.

GT 520, i686 (but could hit x64 just as much, so don't feel save ;-)

I also found https://devtalk.nvidia.com/default/topic/1020399/vdpau-fails-decoding-mpeg2-on-gtx-660-and-384-59/ - that's not me, so I basically confirm the behavior.

There's a suspicious line in the changelog:
Fixed a bug that caused VDPAU playback to be corrupted when extended to coordinates beyond 16384 pixels.


I'm pretty sure that this is an upstream bug and unfixable downstream (but by downgrading)
Need to go for a sysreq to see whether I can get more info on what's going on (nothing in dmesg -w, but the display freezes pretty fast), but I wanted to record the problem for others to find it ;-)
This task depends upon

Sorry, there is nothing to be done here from a packaging standpoint. Please provide information to nvidia to get this fixed in a coming release. Reopen if you truly think I can do something here in the package.
