------- Comment #5 from Arnout Vandecappelle  2009-04-17 15:01 UTC -------
Sounds good!  Except...  that means that the mpeg4videoparse will always be
inserted, even if the stream is already parsed (i.e. coming out of a demuxer or
depayloader).  That incurs some overhead because mpeg4videoparse is scanning
over the stream byte-by-byte.

However, I just did some measurements and it looks like mpeg4videoparse takes
less than 10% of the time of ffdec_mpeg4 (which is already pretty fast).

Conclusion: raise the rank of mpeg4videoparse.
