This doesn't set extradata - you need to extract the codec global headers (such
as H.264 SPS and PPS) at init time to be able to write correct files for some
codecs (such as H.264) with muxers requiring global headers (such as MP4). It
kindof works without it, but the files created will not conform and will not be
usable on some players.
ah that might explain some things (when I play back the encoded video
the quality is pretty lousy)
is there already some code I can use as a reference? I might be out of
my depth here so any help will be more than welcome
