some analysis on the last commit above
this removes vsync 0 from the generic case, non h264 and h264
for the generic case libav seems to incorrectly use vsync 0 by default
thus droping all timestamps, the non h264 case doesnt use -vsync 0 in
our code anymore and for h264, libav uses incorrect reference files
