Yes, this patch looks OK.  It will be included in the next release of 
the source code.

When we're reading a MPEG-4 stream from a file (i.e., not as discrete 
frames), we need to parse the stream in order to figure out where 
'visual objects' etc. start and end.  This is so we can pack data 
into the outgoing RTP packets correctly.  (We also need to parse 
timing information, so we can set the RTP timestamp correctly.)

You're correct, though, that the most detailed parsing of the MPEG-4 
data is left to decoders.
