ffserver: Try matching the RTSP url without a trailing slash

If the client sends PLAY/PAUSE requests with the same url as
specified in Content-Base, these requests may have urls with
trailing slashes.

ffserver: set the sample aspect ratio

Hi.

It seems that ffserver sets sample_aspect_ratio to an invalid value and lavf
rejects it.

I am not sure what I am doing here, but the attached patch actually solves
something: using the following config:

CustomLog -
NoDaemon
RTSPPort 5454
<Stream test1-rtsp.mpg>
Format rtp
File "/tmp/test1-rtsp.mpg"
</Stream>

it allows a somewhat old ffplay (unaffected by the content-base issue I
spoke of in another thread) to play the stream.

Without it, ffserver logs this and closes the stream:

Wed Feb 16 14:52:14 2011 [rtp @ 0x1399de0]Aspect ratio mismatch between encoder and muxer layer

spdifenc: fix byte order on big-endian systems

There is a check for HAVE_BIGENDIAN when outputting the IEC 61937
stream. On big-endian systems the payload data is not byteswapped,
causing in effect the outputted payload data to be in a different byte
order on big-endian than on little-endian systems.

However, the IEC 61937 preamble (and the final odd byte if present) is
always outputted in the same byte order. This means that on big-endian
systems the headers have a different byte order than the payload,
preventing useful use of the output.

Fix that by outputting the data in a format suitable for sending to an
audio device in S16LE format by default. Output as big-endian (S16BE)
is added as an AVOption. This makes the muxer output the same on all
archs by default.

configure: remove early check_deps $ARCH_EXT_LIST

The early disabling of irrelevant arch extensions is no longer
required, and removing it makes dependencies involving these
work as expected.

Clarify that pts_correction* fields are internal to libavcodec
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Set maximum lowres value for the MJPEG decoder to 3.

While 4 works for some samples, 3 is the correct value since 8x8
DCT is used by (m)jpeg.

ffplay: stats: do not dereference NULL video

Also: cosmetic: split this overly long line

VP8: optimized mv prediction and decoding

Merge find_near_mvs and mv bitstream decoding: don't do prediction steps
until absolutely necessary.

Do not fail DVB sub decoding because of a few padding bytes

Instead of returning an error when bytes are left over, just return
the number of actually used bytes as other decoders do.
Instead add a special case so an error will be returned when none
of the data looks valid to avoid making debugging a pain.
