[FFmpeg-devel] Parallelized h264 image corruption bug

Hi all,

I've stumbled upon $subj, which leads to severe image corruption. The 
output seems to miss part of the deblocking in between slices, but IANAC 
so I'm not sure if thats what I'm seeing.

It does not occur with threads=1, only with threads=>1. I also tried to 
unroll the deblock cheat patch, but that did not help. This is on 
current SVN, amd64 build.

Sample is available as ffh264parallel_issue1.mkv (remuxed H264 ES from 
blu-ray) at http://dx.infernix.net/ffh264/ffh264parallel_issue1.mkv as 
well as mplayerhq incoming/h264parallel/ffh264parallel_issue1.mkv.

Please have a look so I can inspect some more sources and ensure that 
things work as intended :)
