- I just received a copy of the MPEG Draft Standard (DIS 11172) dated
- 1992 (rev 2), and thought I would test my understanding of it on the MPEG
- files that XING have released along with their sample player. e.g.
- perpetu5.mpg, flight.mpg, etc. The syntax looks okay, with the files
- starting with sequence_header(), but when I got to the picture_rate
- field, it decoded as (decimal) nine. According to the table under
- section 2.4.3.2 this is a reserved value, and so is not allowed.
- Anybody know what is happening here?
