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.

These have a DXSA tag and contain alpha in addition to
color values for palette.

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.

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.

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.

This was preventing reget_buffer() to return a buffer with the same
data, which was resulting in playback artifacts.

Fix trac issue #116.

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.
