Could you elaborate on why you are adding prefixes to the
actual data? Is this something only your decoder expects
or do all decoders (known to you) expect the extradata
with the prefix you add?
How would the differently prefixed data be written into
mov / mpegts on remuxing?

Thank you, Carl Eugen
