[Mp4-tech][Video][H.264] How to handle errors?

[Ye-Kui.Wang nokia.com]

The video coding standard does not specify how to handle erroneous bitstreams. Parameter sets should typically be transmitted reliably, e.g. using out-of-band means. In case that a decoder detects a syntax error in a sequence parameter set, the best the decoder could do, I think, is to discard that NAL unit as if it were not received, provided that the NAL unit boundary can be detected. But then the coded video sequences referring that sequence parameter set cannot be correctly decoded. In the extreme case, if that sequence parameter set is referred throughout the bitstream, then the video session fails completely.
