streamdump will only record exactly the data received.
rtmp is a format that in contrast to e.g. MPEG-TS has information
about the codecs used etc. only at the very start.
So if you do not have dumpstream enabled from the very start it
will not work.
You should see the exact same effect if you play a .avi,
.mkv, .flv, .mov, .mp4 or ... file (basically almost everything
that is not MPEG-*), the C key will not work with them.
