Description Kusanagi Kouichi 2013-09-02 12:51:31 UTC

Mplayer with VDPAU shows garbage for some videos. The same videos play fine with older mesa. So I bisected mesa and the result is:

53e20b8b418cc85e13d70f41ce160e17847a5096 is the first bad commit

Steps to reproduce:

1. Download 854x480 H.264 video from http://www.bigbuckbunny.org/index.php/download/
2. Play it with mplayer using VDPAU. That is to say, mplayer -vo vdpau -vc ffh264vdpau big_buck_bunny_480p_h264.mov

Thanks for the info, accidentally removed the width/height alignment with this commit.

So any video not aligned to 16 in it's width/height showed this problem.
