bc495bad3d rtsp: Remove a leftover, currently pointless check
This check isn't relevant in the way the code currently works.

Also change a case of if (x == 0) into if (!x).

ad7beb2cac rtpdec: Use our own SSRC in the SDES field when sending RRs
The s->ssrc field is the sender's SSRC, we use ssrc + 1 to get
a collision free "unique" SSRC for ourselves in the RR part.
The SDES block in the RTCP packet should describe ourselves,
not the sender.

This was fixed for the RR part in 952139a322, but wasn't
fixed for the SDES part until now.

This could cause some Axis cameras to send RTCP BYE packets
to us due to the SSRC collision.

2473a45c85 threads: change the default for threads back to 1
Using threaded decoding by default breaks backward compatibility if
AVHWAccel is used or if an appliction sets threadunsafe callbacks.
Avconv and avplay still use -threads auto if not specified.

This temporarily (until 0.8 is released) reverts commit
8e1340abc3. That commit breaks shared
builds because of symbol hiding. Reverting it will enable shared builds
for 0.8

9b6aafba6c mpegvideo: fix invalid memory access for small video dimensions
When either video dimension is only one macroblock, subtractions
based on v_edge_pos and the macroblock size may be negative. In
that situation, an unsigned comparison isn't sufficent to test for
MV overruns, because a limit of (unsigned)-1 will let any other
value pass.

5d95112d92 movenc: Reorder entries in the MOVIentry struct, for tigheter packing
Originally, sizeof(struct MOVIentry) was 48, after the reordering,
it is 40 in my build configuration.

When writing really long mov/mp4 files, this can make a difference
- this saves a bit over 2 MB of memory per hour of video (down to
10.3 MB per hour from 12.3 MB per hour initially) for a video with
75 packets per second - 25 fps + 50 audio packets (which is the
case for AMR audio).

59297ad63d lavf: force single-threaded decoding in avformat_find_stream_info
The H.264 decoder needs SPS and PPS for initialization during
multi-threaded decoding. When probed single-threaded SPS and PPS are
copied to extradata and are available for proper initialization of
the decoder before the first frame is decoded.

e2ff436ef6 lavc: Relax API strictness in avcodec_decode_audio3 with a custom get_buffer()
Do not fail audio decoding with avcodec_decode_audio3 if user has set a
custom get_buffer. Strictly speaking, this was never allowed by the API,
but it seems that some software packages did so anyways. In order to
unbreak applications (cf. http://bugs.debian.org/655890), this change
clarifies the API and overrides the custom get_buffer() with the defaults.

This change is inspired by a similar
commit (c3846e3eba) in FFmpeg.
