its allowed to have some timestamps missing in TS under some
circumstances. so it might be possible to generate a valid file
with the first pts missing (i dont know for sure, id have to check the
spec) also iam not sure what our muxer makes out of that case.
Its certainly better to have valid timestamps on the muxer input
on all frames and let the muxer decide which to store in the file
and which to ommit
calculating valid timestamps for h264/hevc input that ommits some is
not entirely trivial though
