Do not print the results of the conditional call to av_log_ask_for_sample()
into the same line as the main output, separate the already long text.

non-zero, set channels based on channel_layout.

This allows the user to set only channel_layout and not channels.

non-zero, check to make sure they do not contradict eachother.

avcodec_open().

If the encoder has a channel_layouts list and AVCodecContext.channel_layout
is 0, then only print a warning and let the encoder decide how to handle it.

Instead, scalefactors are adjusted by the offset amount, removing the need
for sf_scale, and the MDCT scales are adjusted to compensate for the higher
scalefactors. Floating-point output will be handled by modifying the MDCT
scales.

table values from the spec.

of hardcoding 200 everywhere.

erroring out. A magnitude of 100 corresponds to 2^25 so the will most
likely result in clipped output anyway.

None of the conformance streams fall in the range that need to be clipped.

Decoder relies on previous frame data, so use reget_buffer().

This also set frame->reference to 3, as the frame will be requested
unmodified later so it shouldn't be modified by the application.

Fix playback of file Clock.avi.

The release_buffer was cleaning the provided frame, thus causing the
successive call to avctx->reget_buffer() to allocate a new frame.  In
case the returned frame was not the same one previously returned but a
new one with different data, it resulted in artifacts.

Also deprecate av_get_pict_type_char() in favor of
av_get_picture_type_char().

The new enum and av_get_picture_type_char() are defined in libavutil.
This allows the use in libavfilter without the need to link against
libavcodec.

There is still are still a few sections missing relating to TNS (not present)
and mid/side (contains other bugs).

Overall this improves quality, and vastly improves rate-control.
