22c436c85e rtpdec: Send a valid "delay since SR" value in the RTCP RR packets
Previously, we always signalled a zero time since the last RTCP
SR, which is dubious.

The code also suggested that this would be the difference in
RTP NTP time units (32.32 fixed point), while it actually is
in in 1/65536 second units. (RFC 3550 section 6.4.1)

e568db4025 rtpdec: Calculate and report packet reception jitter
This brings back some code that was added originally in 4a6cc061
but never was used, and was removed as unused in 4cc843fa. The
code is updated to actually work and is tested to return sane
values.

abae27ed3a rtpdec: Fix the calculation of expected number of packets
The base_seq variable is set to first_seq - 1 (in
rtp_init_sequence), so no + 1 is needed here.

This avoids reporting 1 lost packet from the start.

f9eed5d7e6 lavfi/aevalsrc: try to honor specified duration
If nb_samples divide sample_rate and if nb_samples allow it, aevalsrc
should generate the exact amount of samples according to duration.

Example:
aevalsrc=0::n=480:s=48000:d=5.21 should generate 250080 samples.

f6804c3e1b rtpdec: Remove a useless todo comment
The question can be answered: No, we do not know the initial sequence
number from the SDP. In certain cases, it can be known from the
RTP-Info response header in RTSP though. (In that case, we use it as
timestamp origin, but not for rtp receiver statistics.)
