No, don't know that from the top of my head. Personally,
in my software I'm primarily looking at the stream type IDs.
Only if there's doubt about those I'm looking at the
registration descriptors. That works very well for all the
correct and incorrect samples I've seen yet.
If you want to know the registration descriptors and if you
have a Blu-Ray sample with all the formats in them, you
can do "eac3to some.m2ts -logPids". That will list the
registration descriptors of all streams.
