cf3ac54339 vorbis: Replace sized int_fast integer types with plain int/unsigned. 
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

8745e9c458 ac3enc: remove check for mismatching channels and channel_layout 2011-04-27 12:57:43 -04:00
Justin Ruggles
688b09fa59 If AVCodecContext.channels is 0 and AVCodecContext.channel_layout is 
non-zero, set channels based on channel_layout.

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

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.

767848d761 aacdec: remove sf_scale and sf_offset. 
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.

e4744b59aa Large intensity stereo and PNS indices are legal. Clip them instead of 
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.

f4e043ff63 qpeg: use reget_buffer() in decode_frame() 
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.

4f2954e232 smacker: remove unnecessary call to avctx->release_buffer in decode_frame() 
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.

bebe72f4a0 lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enums 
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.
