Reproduce steps:
mplayer -vo vaapi -va vaapi -fps 25 HD.Club-Alisan.Trailer-80Mbps.mpg
then resize the video winodw
Comment 1 Hai 2010-12-28 01:36:03 UTC
For Ironlake, this issue won't happen. So it's a regression.
Comment 2 Hai 2010-12-28 02:01:59 UTC
For an mpeg2 SD file, resizing it also may cause GPU to hang
The previous stack is printed by mplayer automatically.
Following is using cat /proc/2816/stack to get the stack(2816 is the pid of mplayer)

Comment 3 haihao 2010-12-28 16:54:15 UTC
Even if this issue exists, I don't think it is a regression.
Comment 4 Hai 2010-12-28 17:49:41 UTC
Yes, it's not a regression. Sorry about it.
Comment 5 haihao 2010-12-28 18:42:20 UTC
It works fine on my destop and zhenyu's mobile machines .  What is your stepping?
Comment 6 Hai 2010-12-28 18:59:32 UTC
My stepping is 6
Comment 7 Gordon Jin 2010-12-28 19:11:37 UTC
Hai: Haihao was asking for graphics revision (see lspci), not cpu stepping.
Comment 8 Hai 2010-12-28 19:22:42 UTC
The graphics revision is 08.
Comment 9 haihao 2010-12-28 23:30:07 UTC
Could you try the latest master branch?
Comment 10 Hai 2010-12-28 23:52:25 UTC
I have tried it with the latest master branch.This issue still happens. But when I use another sandybridge test machine(graphics revision is 09), this issue won't happen. So I think maybe it is a hardware issue.
Comment 11 haihao 2010-12-29 19:12:14 UTC

Comment 12 haihao 2010-12-29 19:19:23 UTC
How about the result after exchanging the disks?
Comment 13 Hai 2010-12-29 21:50:55 UTC
I have used this harddisk with Sugarbay. This issue won't happen. So it can be proved as a hardware issue.
Comment 14 Hai 2010-12-29 22:02:30 UTC
or a bios issue.
Comment 15 haihao 2010-12-30 21:47:46 UTC
VAAPI works fine with Zhenyu's disk on this machine. So something should be wrong on your disk.
Comment 16 Hai 2011-01-04 22:41:30 UTC
We have reinstalled a new OS and tested it on Huron River. The issue still happens occasionally. So I reopen it and the improtance can be medium.
Comment 17 haihao 2011-01-04 23:01:33 UTC
I don't think it is related to OS. it is better to build all components on this machine, not just copy from your build machine.
Comment 18 haihao 2011-01-09 18:39:58 UTC
I can't reproduce this issue on HuronRiver (the revision is also 8). Could you detail how to reproduce this issue? BTW, please attach your xorg.0.log.
Comment 19 Hai 2011-01-10 22:19:33 UTC
Created attachment 41867 [details]
Comment 20 Hai 2011-01-10 22:23:09 UTC
Reproduce steps:
mplayer -vo vaapi -va vaapi -fps 25 TS1080i25_h264cab_10mbs_sally-0xe0.264  
then press "f" to switch to full screen frequently.

Are you sure this is a MPEG2 issue?
Comment 22 Hai 2011-01-11 01:11:47 UTC
both of TS1080i25_h264cab_10mbs_sally-0xe0.264 and HD.Club-Alisan.Trailer-80Mbps.mpg have the same issue.
Comment 23 haihao 2011-03-14 19:56:20 UTC
Can you reproduce this issue now ?
