Ganesh Ajjanagadde	11f0acf829	avcodec/mpegaudio: use predefined M_SQRT2 M_SQRT2 is defined in math.h, or in avutil/mathematics.h for compatibility hacks. This uses this value instead of an ad-hoc define. Fixed point values produced by FIX() remain identical.

Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	9 years ago

Michael Niedermayer	268b1eae22	avcodec/mpegaudioenc_template: default to 384k bitrate as default If 384k is too high for the samplerate, choose the closest possible Idea to increase the bitrate from: `46439e1562` Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	9d66aa2c8f	avcodec/mpegaudioenc_template: dont crash on bitrate=0 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	babb611d35	libavcodec/mpegaudio: change CONFIG_FLOAT to USE_FLOAT The CONFIG_ name-space is set by configure, so its better to use a different prefix here. This also unifies the encoder & decoder define that is used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	04e06cdf7d	avcodec: split mp2 encoder into float and fixed This makes the USE_FLOATS == 0 available to the end user More float optimizations can easily be added as well now common code should be factored out into a common file once all fixed point & floating point optimizations are done, this is to avoid having to move code back and forth between files.

Mans Rullgard	2e2b8ef8e0	mpegaudio: move ff_mpa_enwindow to a separate file This table is used only by mpegaudiodsp and mpegaudioenc. Separating it allows dropping some dependencies from mpc[78] and qdm2. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
