vdpau fails on mp4 file

Cc: Ticket locked: no


Playing an mp4 file from the TED website I'm sure worked fine with vdpau in 0.22. I've just tried with 0.23 (having not played the file for a while) and it complains of A/V sync failure. The log (-v playback) indicates more than this going on.

The file is available from

Problem occurs with both nvidia-drivers-195.36.15 and the older nvidia-drivers-190.53-r1 (Gentoo version numbers?)

Not a MythVideo? issue. Mark, this is the same issue I shared with you a few months back, please feel free to deal with it as you like.

Resolution: fixed
Status: assignedclosed

(In [24237]) Add additional VDPAU hardware decoder check for H264 video streams with certain widths that may not be supported on certain NVIDIA chipsets.

See Appendices A and H of the NVIDIA driver readme for the combinations of H.264 video widths and cards that may be unsupported.

Closes #8275.

If this proves to be trouble free, I will backport to release-0-23-fixes in a few days.
