Hi, Thanks i'll look into the issue and come up with an ETA ASAP. Going on I will be the maintainer of VDPAU. Please direct any VDPAU issues to me.

This is the issue that the hevc low level decoder outputs frames instead of fields - which all the other decoders do. Originally, the vdpau support didn't account for this at all - so it would take the memory allocated for the progressive frame and then treat it as two fields and return those two fields up (because vdpau assumes output frames are made up of two fields too) which lead to garbage output, as it would either return the top and bottom half in each 'field' if using the opengl interop, or it would interleave the two 'fields' when returning a frame using the read-back API or the vdpau mixer. I pointed this out to the vdpau maintainer (back when he still worked for nvidia) and he fixed the vdpau mixer case - but read-back and opengl remained broken. He then left nvidia and no work has happened ever since - that was almost two years ago. --phil _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
