Comment 1 haihao 2012-12-27 07:32:36 UTC 
SA10107.vc1 is an interlaced file.  Could you help to check other files ?
Comment 2 haihao 2012-12-27 07:33:58 UTC 
Lower the priority for interlaced files
Comment 3 Du Yan 2012-12-27 07:58:56 UTC 
our tool can't check VC1 profile. and all the files in the list can't be decoded and cause mplayer crashed.
Comment 4 haihao 2012-12-27 08:04:42 UTC 
Yeah, there is an assertion for interlaced file in the driver.  Do you see the following message when playing back these files ?

...
[vc1 @ 0x89615a0]Interlaced frames/fields support is incomplete
Comment 5 Du Yan 2012-12-27 08:16:37 UTC 
OK, i check all the files and they are all interlaced stream.
Comment 6 Ouping Zhang 2013-01-04 02:01:03 UTC 
driver didn't support VC1 interlace decode.
