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.

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.
Longer discussion of the topic:
http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/128582
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.
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.

Use av_log() rather than fprintf(stderr, ...), and show information
related to the previous size/pixel format configuration.
Consistent with the corresponding message issued in case of audio
configuration change.

Looks better for some cases, worse for others, overall not much difference.
Its more correct though.

Just some cosmetics & comments, the only functional change
"error_resilience: use s->last_picture for accessing last MVs."
Is so buggy that it needs a full rewrite, guess -1.0 PSNR loss wasnt
enough for ronald to realize there was a problem.
