59f733d1b1 2x faster ff_h264_init_cabac_states(), 4k cpu cycles less.
Sadly this is just per slice so the speedup with normal files should be negligible.

fc78b0cb7e Remove first_rtcp_ntp_time. This is used to prevent overflow of the timestamp,
but doesn't actually do that. What's worse, it creates timestamp adjustments
that are different per stream within a session, leading to a/v sync issues.

See discussion in thread "[FFmpeg-devel] rtp streaming x264+audio issues (and
some ideas to fix them)". Patch suggested by Luca Abeni <lucabe72 email it>.

9c8fa20d7e When using RTP-over-UDP, send dummy packets during stream setup, similar to
what e.g. RealPlayer does. This allows proper port forwarding setup in NAT-
based environments.

f47a7cb777 Move read_line() and write_line() definition from pixdesc.h to
pixdesc.c, which are now not anymore marked as static inline.

Fix the inclusion of the private header intreadwrite.h in the public
header pixdesc.h.

a636b58ce1 Fix two problems (no idea how this ever worked):
- the return value of url_open_dyn_*buf() is 0 on success, so using
   if (!(res = url_open_dyn_*buf())) return res; is not going to work
- url_open_dyn_packet_buf actually writes the max_packet_size before
   each piece of data. Feeding this to the ASF demuxer will never work.
   Therefore, use url_open_dyn_buf() instead.

298d2fd304 Don't return 0 if buffer setup failed. That signals the RTSP demuxer that
the packet was filled in, leading to virtually random behaviour in the
decoder later on. Instead, return a negative value.
