[Mp4-tech] Add some errors in H.264 bitstream

[Thomas Dove]

Judy,
We already sell some sets of 'error' video test clips for H.264/AVC, called 'Vclips'.
These clip sets incorporate errors that we have seen in real customer bitstreams from a large number of customers, over the past 18 months (while selling the Vprove analysis software tool).
The error types include:
- encoder errors (syntax errors, out-of-range values, elements not permitted in a particular Profile/Level, etc.)
- transmission errors
- errors due to the way the Elementary Stream is packed into a transport/container stream
They provide a pretty extensive (independent) test covering a range of the common errors that your decoder is likely to have to deal with.
There are 3 clip sets (each clip set incorporates many test streams):
- VC-311 for Baseline Profile
- VC-312 for Extended Profile
- VC-313 for Main Profile
Every test stream of every set has detailed documentation on the error, the consequences of the error, what the correct value is, and the syntax of the bitstream.
These are available off-the-shelf (they have been available for around 9 months now), and are used by many companies around the world (such as Philips, Texas Instruments...).
