https://bugs.freedesktop.org/show_bug.cgi?id=98914 --- Comment #12 from Jörg-Volker Peetz --- Thanks for the patch. I reviewed and tested it ok. The hardware accelerated mpeg2video codec works, e.g., with mpv. So, my five years old notebook is "very" old :-(. I did all testing with the integrat

https://bugs.freedesktop.org/show_bug.cgi?id=98914 --- Comment #10 from Jörg-Volker Peetz --- Please, go ahead and commit the patch. I think there might be many computers which could and do use this hardware acceleration. The mpeg2video codec applies to DVD's for example. Although IMO, the choi

https://bugs.freedesktop.org/show_bug.cgi?id=98914 --- Comment #9 from Christian König --- Yeah, the problem is on line 155 in that file. Here "i" is used as signed and the calculation result can be negative. Brave enough to create a patch for this or should I do that? Thanks for the help and

https://bugs.freedesktop.org/show_bug.cgi?id=98914 --- Comment #8 from Jörg-Volker Peetz --- Thanks for caring and your git lesson. The culprit is the change in src/gallium/auxiliary/vl/vl_zscan.c . I double-checked by starting from mesa-13.0.2 and just reverted the type change in that file bac

https://bugs.freedesktop.org/show_bug.cgi?id=98914 --- Comment #5 from Jörg-Volker Peetz --- Meanwhile, I've tried version 13.0.0-1 from the debian snapshot archive. It shows already the same regression for the vdpau hardware acceleration with mpeg2video codec. I've also cloned the mesa git repo

https://bugs.freedesktop.org/show_bug.cgi?id=98914 --- Comment #4 from Michel Dänzer --- Is it already broken with 13.0.0, or only with 13.0.1? If the latter, I'm afraid it might be due to https://cgit.freedesktop.org/mesa/mesa/commit/?h=13.0&id=9c297c5487bf5464f75ffd5e11ad6aaad92915a9 . -- Y
