* Replace deprecated av_get_pict_type_char() with av_get_picture_type_char().Stefano Sabatini2011-05-02
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* dpx: Do not use DPX encoder for decoding.Kostya Shishkov2011-05-02
| | | | 10l to the one who hasn't checked this.
* ALPHA: Replace sized int_fast integer types with plain int/unsigned.Diego Biurrun2011-05-01
| | | | | | 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.

* ac3enc: clip large coefficient values and negative exponents rather than usingJustin Ruggles2011-05-01
| | | | av_assert2().
* ac3enc: do not store a bandwidth code for each channel.Justin Ruggles2011-05-01
| | | | | Although AC-3 allows it, it's not very useful. The encoder uses the same code for all full-bandwidth channels.
* ac3enc: remove bandwidth reduction as fallback for bit allocation failure.Justin Ruggles2011-05-01
| | | | | It was only needed at low bitrates, which now already use a low bandwidth, so the bandwidth reduction is no longer needed.
* ac3enc: merge compute_exp_strategy_ch() into compute_exp_strategy()Justin Ruggles2011-05-01

* ac3enc: return error if frame+exponent bits are too large instead of usingJustin Ruggles2011-05-01
| | | | | | av_assert2(). This can occur in some very rare cases with low bitrates.
* ac3enc: differentiate between current block and reference block in bit_alloc()Justin Ruggles2011-05-01

* AMV: disable DR1 and don't override EMU_EDGEMichael Niedermayer2011-04-29
| | | | | | | | | | | | This works around a possibly exploitable crash. Appearently, vlc can be exploited with a malicous file. This should get reverted as soon as a proper fix is found.

* ac3enc: remove check for mismatching channels and channel_layoutJustin Ruggles2011-04-27
|
* If AVCodecContext.channels is 0 and AVCodecContext.channel_layout isJustin Ruggles2011-04-27
| | | | | | non-zero, set channels based on channel_layout. This allows the user to set only channel_layout and not channels.
* If AVCodecContext.channel_layout and AVCodecContext.channels are bothJustin Ruggles2011-04-27

* Check AVCodec.supported_samplerates and AVCodec.channel_layouts inJustin Ruggles2011-04-27

* aacdec: remove sf_scale and sf_offset.Alex Converse2011-04-27
| | | | | | | 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.
* aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficientJustin Ruggles2011-04-27

* Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets insteadAlex Converse2011-04-27

* Large intensity stereo and PNS indices are legal. Clip them instead ofAlex Converse2011-04-27

* qpeg: use reget_buffer() in decode_frame()Stefano Sabatini2011-04-27
| | | | | | | | | | | 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. Signed-off-by: Ronald S.

* smacker: remove unnecessary call to avctx->release_buffer in decode_frame()Stefano Sabatini2011-04-27
| | | | | | | | | 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. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enumsStefano Sabatini2011-04-26
| | | | | | | | | | | | 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.
