Precisely. There is a chicken and egg issue when dealing with
discontinuities inside the stream without knowing how the demux should
handle it short of providing a discontinuity callback to the stream with
all the "when should we trigger it" issues.
For now, without overhauling the whole stream process I don't see the
point to keep flags which will be discarded anyway.
Even with a better architecture, knowing you have a discontinuity
doesn't even mean you can recover. MKV could (and already does as best
as he can without it since it doesn't trust anything). MP4 not segmented
I'm afraid your index is screwed anyway. AVI (lol). Can't tell for ASF
and all the other esoteric ones.
And to answer Thomas, adding a discontinuity packet for TS was, imho,
the smartest way to do that.
