I'm not sure where to put this issue, but as this series seems to have some effect on it, here it is :
I am trying to play a mpeg2 video with a 4:2:2 subsampling using mplayer, with vdpau video output and regular ffmpeg12 video codec (the mesa mpeg2 decoder cannot handle 4:2:2 subsampling anyway if I read previous discussions right ?). With lateset mesa git master I had completly borked output and this error : [vdpau] Error when calling vdp_video_surface_put_bits_y_cb_cr: No backend implementation could be loaded. With the previous series of 9 patches I had that output : http://img9.imageshack.us/img9/7447/yv422bug.png With today series I get that output : http://img807.imageshack.us/img807/5593/cran07032012184105.png By the way something seemed wrong while reading mplayer's log : (the use of the software scaler and the "DRI failure") Starting playback... Could not find matching colorspace - retrying with -vf scale... Opening video filter: [scale] Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
