Fixes encoder private options, which are broken now in ffmpeg, because
opt_default2() can't find them, thus making opt_default() to fail.

By observation it did not seem to handle prev_frame_num > frame_num.
This does not affect any files I have.

The output type of the AV_RL32/AV_RB32 macros was signed int. The
resulting overflow broke at least some ASF streams with large
timestamps. Fix by adding a cast to uint32_t.

One of the causes of this bug is that the h264 parser defaults low_delay
to 1, but the h264 codec defaults low_delay to 0. Really Ugly.

After many hours of looking at this, I'm still not sure how has_b_frames
is *intended* to behave, but to me the implementation appears way more
complicated than it ought to be.

My patch relies on the encoder to set an optional field in the SPS. This
works for libx264 streams, but I'm not sure that all h264 encoders will
set it.

They've been replaced by demuxer private options.

It stores options in a dictionary to be passed to new open calls.

It will replace opt_default once all the pieces are in place.

It supports more convenient setting of AVOptions.

Deprecate the last remaining member of AVFormatParameters.

Add support for demuxer private options.

This way the caller can pass all the options in one nice package.

It's broken with multiple files or video streams.

It's broken with multiple files or video streams.

Fixes choosing supported samplerate and framerate.

There's no point in keeping them separate.

In this case, the string that was passed couldn't contain
user-defined data and thus there was no risk for injection
bugs, but it's safer this way, if we later change the
content of the options string.

This fixes a segfault when using the C version of ac3dsp.float_to_fixed24().

This removes the default samplerate of 44100 for raw input, hence all
the FATE changes.

Some MMX2 functions were being referenced without proper #ifdefs.

The comment should have been placed only in
yuv2rgb48_X_c_template, not yuv2rgb48_1_c_template.

This is part of the Great Evil Plan to simplify swscale. Note that
you'll see some code duplication between the output functions for
different RGB variants, and even between packed-YUV and RGB
variants. This is intentional because it improves readability.

YUV planes were marked as uint16_t, but they contained signed data.
Fixes issue 1108 and 675.
