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.

df018207f9 doc/ffserver: remove paragraph in the introductory blurb

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.)
