Hi!

I use the following setup : gstreamer-vaapi -> libva -> vdpau-driver -> radeonsi. I noticed that vop_time_increment_resolution was passed to the vdpau-driver, but not time_increment itself. Then in vdpau-driver/src/vdpau_decode.c, translate_VASliceDataBuffer(), when we regenerate the data of the slice header, we have this line, around 545 :

put_bits(&pb, time_incr, 0);            /* time increment */

which sets this value to zero, because time_incr here is computed as the number of bits needed depending of time_increment_resolution, not the time_increment value itself. This causes an effect in the decoded stream where some squares appear too late in the image, some kind of a "mosaic" effect in fast moving areas.

is adding this supplementary field to the struct the best solution ?
