I am sure that i know what is going on, NVENC is inserting wrong SPS
VUI aspect_ratio_idc to h264 packets when you encode at resolution
720x576 and 720x480
AR 16:9 will insert aspect_ratio_idc=4 but it should be
aspect_ratio_idc=255, sar_width=64, sar_height=45 for 720x576
AR 4:3 will insert aspect_ratio_idc=2 but it should be
aspect_ratio_idc=255, sar_width=16, sar_height=15 for 720x576
MP4 and MKV containers contains correct AR metadata information which
all players should accept, but TS container has nothing like that so
it relies on what is inside h264 SPS.
Makes sense. So, I think this really needs fixing inside the driver.
Having to do the whole parse/rewrite thing is horrible - and that's
even after rewriting it not to re-implement the parser.
