Originally, I was returning (as part of the old code legacy), the pixelformat directly related to the codec: e.g: returning AV_PIX_FMT_VDPAU_H264. But this cause h264 playback to fail. so I now always return AV_PIX_FMT_VDPAU in my get_format. Interestingly, when I do like what everyone else appear to be doing, like: while(*cur != PIX_FMT_NONE) { if (*cur == AV_PIX_FMT_VDPAU) return *cur; cur++; } return avcodec_default_get_format(avctx, fmt); for WMP3, the PixelFormat received is AV_PIX_FMT_VDPAU_WMP3, but there's no AV_PIX_FMT_VDPAU in the list that follows. Wrong order in the pixel format is my guess.

I still have no idea why it was changed at all. there must be something different. I have a few mpeg2 video that do not play with the old API, but do now. like the one reported here: https://code.mythtv.org/trac/ticket/11377 thanks again for you help... much appreciated _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
