[FFmpeg-devel] [PATCH] (for discussion): nvenc: fix wrong aspect ratio for 720x576 and 720x480 resolution

[Miroslav Slugeň]

This patch is for discussion only, not ready to commit yet and maybe 
newer will be.

NVENC in current CUDA 8 SDK is setting wrong aspect ratio when encoding 
resolution 720x576 and 720x480 and using AR 4:3 or 16:9 it will encode 
to h264 header that 15:11 and 20:11 is used. This is very very very ugly 
way how to fix it. I hope someone in NVIDIA will fix this soon, because 
all encoded streams are not displayed correctly for example in videojs 
player.

Support for HEVC is currently broken.
