Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	0b37cccaab	ra288: convert VLAs to fixed size Originally committed as revision 23832 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	b1078e9fe6	Move clipping of audio samples (for those codecs outputting float) from decoder to the audio conversion routines. Originally committed as revision 22937 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Vitor Sessak	66d4c62806	Do not reimplement ff_celp_lp_synthesis_filterf(). Originally committed as revision 17562 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Vitor Sessak	08c433972e	Use ff_dot_productf() in ra288.c Originally committed as revision 15757 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Vitor Sessak	d552d04dc9	Simplify: avoid duplication backward_filter() Originally committed as revision 15428 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Vitor Sessak	64e4af2ac1	Do instead of divising a float by a constant, multiply by its inverse Originally committed as revision 15417 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	b6c7758168	Move constant multiplication out of the loop Originally committed as revision 15404 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	e60daa340b	Cosmetics: move convolve() together with the other DSP functions Originally committed as revision 15403 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	a987a126fd	Simplify: move division by constant off the loop Originally committed as revision 15402 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	645a6be1e7	Merge the 2 lpc loops. This changes the output by (stddev: 0.21 PSNR:109.51, file:ddinterview28.ra), the changes are due to float rounding inaccuracies and do not happen if doubles are used. Originally committed as revision 15394 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	571bbaf814	Factorize lpc code slightly. Originally committed as revision 15393 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	faf6d6964b	Use SAMPLE_FMT_FLT instead of doing the float->int conversion in the decoder. This changes the output very little and any difference should be inaudible. Originally committed as revision 15343 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	9547cadb8d	Cosmetics: line breaks Originally committed as revision 15308 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	111734de09	Simplify: use a single history buffer for gain and a single one for speech instead of having two for each in the context. Originally committed as revision 15307 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	9c10ab6cd1	Cosmetics: align spec references Originally committed as revision 15300 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	fd8897e803	Convert table to integer. Originally committed as revision 15292 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	1be0fc2909	Avoid duplicating compute_lpc_coefs() function in both the RA288 and AAC decoders. Originally committed as revision 15193 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	8089c652a7	Check *data_size in decode_frame() Originally committed as revision 14636 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	5991704634	Cosmetics: alignment Originally committed as revision 14635 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	e3751aa6ec	Flip (by making buf[i] -> buf[size-i-1]) two buffers: {sp,gain}_block. This needs duplicating a few loops, but now the code is clearer. Originally committed as revision 14634 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	6888b4fcec	Rename prodsum() function to convolve() Originally committed as revision 14615 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	4ca7e74c1f	Do not declare a counter as unsigned when it is not needed Originally committed as revision 14469 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	4e33ed368a	Cosmetics: rename loop counter vars to i,j Originally committed as revision 14468 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	045e21cc19	Cosmetics: new line Originally committed as revision 14457 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	e7e4f476c0	Remove the now useless phase variable from context Originally committed as revision 14456 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	c749f3db98	Cosmetics: make comment match var name Originally committed as revision 14454 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	6509507fad	Cosmetics: align comments Originally committed as revision 14453 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	f285e6dd31	Rename two context vars: s/sb/sp_block/, s/lhist/gain_block/ Originally committed as revision 14452 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	36826ee0df	Declare temporary buffers to be only of the necessary size Originally committed as revision 14451 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	5e707c5905	Remove redundant comments Originally committed as revision 14450 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	c6ad13044a	Cosmetics: do not align with now removed next instruction Originally committed as revision 14449 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	2c46367163	Cosmetics: remove braces and useless newline Originally committed as revision 14448 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	2b356efec2	Change the way the input is passed to do_hybrid_filter(). Before, in[0] was the oldest input sample passed and in[n-1] was the latest. Now it is the contrary. This allows making backward_filter() somewhat simpler. Originally committed as revision 14447 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	aed39f6c02	Remove RA288Context.output buffer. This buffer is just RA288Context.sb backwards (output[i] == sb[N-i], where N is the buffer length). This makes the code slower, this will be fixed in my next commit. Originally committed as revision 14446 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	b26d320583	Add a few comments pointing to the G.728 specification Originally committed as revision 14444 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	854ce441c3	Remove the history buffer from the context. It can easily be evaluated from the lhist buffer. Originally committed as revision 14443 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	0143ec2a7e	Rename two context buffers: pr{1,2} -> {sp,gain}_lpc. Also add a few doxy comments. Originally committed as revision 14437 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	59da0390dc	Remove st1 and st2 temporary buffers in backward_filter() and use instead RA288Context.pr{1,2}. Note that the pr{1,2} buffers are one unity smaller than the st{1,2} buffers. My guess is that the original coder decided to add one to the array sizes "just to be sure". Originally committed as revision 14435 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	3df136d438	Change slightly the meaning of RA288Context.phase. This allows to remove two intermediary buffers and avoid a few memcpy's. Originally committed as revision 14432 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	f42eb5715d	Remove st1 and st2 variables from context, since they could be just local vars Originally committed as revision 14421 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
