Wouldn't it be better to replace next_byte by something like
int next_chunk(mpg_id self, int buffersize, unsigned char* buffer)
(returning of course the number of bytes actually written to the buffer)?
It seems to me that calling a function for every byte of data
is rather bad for the performance. Best,
Martin
