If a MP3 file contains the string NSVs, the NSV probe will think it is a NSV file instead of a MP3 file. Check for 0xBEEF after a Video/Audio chunck for more accuracy.

libavformat/utils: Only consider dvb teletext timestamps for start time when they are consistent with the rest.

This fixes Ticket51.

It seems sws-PPC did hardcode 2048 at various places instead of using VOFW.
This also means that all past VOFW benchmarks on PPC are meaningless

The QuickTime RLE encoder only supports 16, 24, and 32-bit color. This patch adds support
for 8-bit grayscale.

This FourCC is used by "mpegable AVC" codec and the file encoded with this codec decodes correctly with FFmpeg's H264 decoder.

Also delete some unused deblock asm macros.

The file does not decode correctly yet the checksums match this wrongly
decoded file. Thus the checksums must be wrong.

framecrc returns different values when one swiches endianness,
this apparently has been missed by "the fork" who added the 10bit fate
tests. Sorry for missing this during the merge.

On cygwin, math.h needs to be included before float.h because of a bug
in the system headers. Including libavutil/libm.h first works around
this issue.

Fix decoding of file b.tif, trac issue #168.

The softfloat functionality is unused, not installed and incomplete.
On platforms without floating point units, the compiler provides a softfloat
implementation so there is no point in carrying this code around locally.

Tested to fix Haiku H264/10bit fate failures, may also fix others.

This fixes the warnings:
tests/rotozoom.c:252: warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result
tests/rotozoom.c:254: warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result

This is more like what VLC does. If the server doesn't mention
supporting GET_PARAMETER in response to an OPTIONS request,
VLC doesn't send any keepalive requests at all. After this patch,
libavformat will still send OPTIONS keepalives if GET_PARAMETER
isn't explicitly said to be supported.

Some RTSP cameras don't support GET_PARAMETER, and will
close the connection if this is sent as keepalive request
(but support OPTIONS just fine, but probably don't need any
keepalive at all). Some other cameras don't support using
OPTIONS as keepalive, but require GET_PARAMETER instead.

In output_packet(), move the pre_process_video_frame() call inside the
if (ist->decoding_needed) { } block. This way
pre_process_video_frame() is not called when stream-copy has been
selected.

Also simplify.
