Andreas Rheinhardt 14644e3322 cbs_mpeg2: Fix parsing the last unit There is one way to find out if avpriv_find_start_code has found a start code or not: One has to check whether the state variable contains a start code, i.e. whether the three most significant bytes are 0x00 00 01. Checking for whether the return value is the end of the designated buffer is not enough: If the last four bytes constitute a start code, the return value is also the end of the buffer. This happens with sequence_end_codes which have been ignored for exactly this reason, although e.g. all three files used for fate tests of cbs_mpeg2 contain sequence_end_codes.
