Michael Niedermayer	2e4413ce2c	g722enc: switch to ff_alloc_packet2() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	bb03b6f7b1	g722enc: use AVCodec.encode2() FATE reference updated due timestamp rounding because of resampling from 44100 Hz to 16000 Hz in avconv.	13 years ago
Martin Storsjö	b087ce2bee	g722: Fix the QMF scaling This fixes clipping if the encoder input used the full 16 bit input range (samples with a magnitude below 16383 worked fine). The filtered subband samples should be 15 bit maximum, while the code earlier produced them scaled to 16 bit. This makes the decoder output have double the magnitude compared to before. The spec reference samples doesn't test the QMF at all, which was why this part slipped past initially. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Justin Ruggles	8e2555d3b1	g722enc: check for trellis data allocation error	13 years ago
Justin Ruggles	cf1a259ad6	g722enc: validate AVCodecContext.trellis	13 years ago
Justin Ruggles	77c5b66cbe	g722enc: set frame_size, and also handle an odd number of input samples The fate reference is updated because the previous test skipped a sample in each encode() call due each input frame having an odd number of samples.	13 years ago
Justin Ruggles	34093ba081	g722enc: split encoding into separate functions for trellis vs. no trellis	13 years ago
Diego Biurrun	da9cea77e3	Fix a bunch of common typos.	13 years ago
Sjoerd Simons	f32fd31858	g722: Change bits per sample to 4 Earlier, bits per sample was defined as 8, since bits_per_coded_sample was used to indicate whether to ignore the lower bits of the codeword, having values 6, 7 or 8. g722 encodes 2 samples into one byte codeword, therefore the bits per sample is 4. By changing this, the generated timestamps for streams encoded with g722 become correct. This makes timestamp generation for g722 data correct (both when encoding and when demuxing from raw g722 files). Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Michael Niedermayer	8b7dc087e4	Add forgotten const to enum AVSampleFormat Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Martin Storsjö	c41eb2ade4	libavcodec: Use "const enum AVSampleFormat[]" in AVCodec initialization Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
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

Martin Storsjö	8bd1956462	g722: Move the low_inv_quant6 table up to the common tables Since SVN rev 25866, this table is used by the trellis encoder, too, not only by the decoder. Originally committed as revision 26065 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Martin Storsjö	c6fe83a3e0	g722: Add a trellis encoder The structure is largely based on the trellis encoder in adpcm.c. Originally committed as revision 25866 to svn://svn.ffmpeg.org/ffmpeg/trunk	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
Martin Storsjö	21e681ba57	Add a G.722 encoder Originally committed as revision 25164 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Martin Storsjö	58e37eafce	Add G.722 ADPCM audio decoder Originally committed as revision 25086 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
