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.
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 remove unnecessary call to avctx->release_buffer(). reget_buffer
is required since apparently the codec needs to be feeded with the
previous frame data.
Releasing the frame and using get_buffer was working only in the case
get_buffer() was returning the old frame data, and resulting in
playback artifacts otherwise.
Fix trac issue #85.

Store palette data in the codec context, do not assume that the frame
allocated the first time by avctx->get_buffer will be returned again.
This requires to store the palette which comes with the first frame in
the context, and copy it to the following frames.

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.

This is required for setting up the filterchain, as it requires the
pixel format to be set, which is usually done when probing the file
with av_find_stream_info().
