Ok, this is a weird one... Lately I've been finding some videos are not playable using mplayer on my media center frontend. Which is kind of, you know. It's job. These videos pretty much hang with the message: Unexpected decoder output format Planar YV12 repeated constantly. Now the funny thing is they play just fine on another machine, with hthe same version of Ubuntu, same version of mplayer, same version of the nvidia binary driver, same vdpau, etc. The only difference I can find is this. When I run "vdpauinfo" on the media center, I get (among other results) this: Decoder capabilities: name level macbs width height ------------------------------------------- MPEG1 0 8192 2048 2048 MPEG2_SIMPLE 3 8192 2048 2048 MPEG2_MAIN 3 8192 2048 2048 H264_MAIN 41 8190 2032 2048 H264_HIGH 41 8190 2032 2048 VC1_SIMPLE 1 8190 2048 2048 VC1_MAIN 2 8190 2048 2048 VC1_ADVANCED 4 8190 2048 2048 On the machine that IS capable of playing the videos, I get all those and in addition get these: MPEG4_PART2_SP 3 8192 2048 2048 MPEG4_PART2_ASP 5 8192 2048 2048 DIVX4_QMOBILE 0 8192 2048 2048 DIVX4_MOBILE 0 8192 2048 2048 DIVX4_HOME_THEATER 0 8192 2048 2048 DIVX4_HD_1080P 0 8192 2048 2048 DIVX5_QMOBILE 0 8192 2048 2048 DIVX5_MOBILE 0 8192 2048 2048 DIVX5_HOME_THEATER 0 8192 2048 2048 DIVX5_HD_1080P 0 8192 2048 2048 This is the only difference I can find. And I have NO IDEA where it's coming from, or if it has anything to do with anything, or if ANY of this makes any kind of sense. Anyone have any ideas?... --
