This is an experimental proposal for issue #2881.
The
CRcvBuffer::getFirstNonreadSeqNo()
returns the sequence number of the first packet that cannot be read from the buffer. This includes the first missing packet and the first packet of a several packets long message, if not all packets of the message exist yet. Due to the latter case, the proposed solution is not accurate in a message mode of SRT when TSBPD is disabled. When TSBPD is enabled, a message must always be one packet long.There is a broader rework of the RCV buffer in PR #2527. However it may not end up in v1.5.4 due to some testing already performed with the existing RCV buffer implementation. Therefore this PR may be considered a temporal fix of #2881 until #2527 is merged.
