I think it would be nice to add an event like AVSTREAM_EVENT_FLAG_STREAM_ADDED and raise it in avformat_new_stream(), on both the stream itself and the format context. It ought to work for all existing formats out of the box. > Adding STREAM_ACTIVE is not really necessary since you would notice while > sending STREAM_GONE/NO_CARRIER should deliver enough interesting information > to the user (that then could react to the fact that stream is finished, e.g. > by closing the file if he was saving that specific stream) > > That if I understood correctly how the carrier signal is working. To clarify, NO_CARRIER doesn't necessarily mean that the stream in question is finished, just that it hasn't had any presence since the last time the user reset the events. For some formats this might mean that it's finished, but for MPEG-TS in particular it just means that no packet related to the stream has been seen in that time. The format provides no way to conclusively determine whether it's there or not, so it's up to the user to determine when to consider it actually dead.
