2013-11-16Replace all instances of avcodec_alloc_frame() with av_frame_alloc().Anton Khirnov
2013-10-04cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun
2013-09-27pcm: support 24-bit/32-bit little-endian planarPaul B Mahol
Used by LXF. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-08-31pcm_dvd: consolidate pieces from pcm.c and mpeg.cChristian Schmidt
Remove the header decoding for PCM audio from mpeg.c and the 20/24bit parts from pcm.c and merge them into a new decoder in pcm-dvd.c. The decoder has added support for samples that span multiple packets and modified 20/24bit group decoding. Both is needed to decode samples that have been generated with DVD-Lab Pro 2. The decoding of 16bit PCM and two channel 24bit is identical to before. No other samples are known to verify the correctness of the encoding this software does. The complete list of tested formats is 48kHz/16bit/2-8 channels 48kHz/24bit/2-5 channels 96kHz/16bit/2-4 channels 96kHz/24bit/2 channels Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
2013-07-12pcm: always use codec->id instead of codec_idLuca Barbato
Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-02-12pcm: decode directly to the user-provided AVFrameJustin Ruggles
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-11-20pcm: fix decoding of pcm_s16le_planar on big-endianJustin Ruggles
The sample count is decremented by the DECODE() macro and needs to be reset in each loop iteration. Also, DECODE() increments the src pointer so that does not need to be done separately.
2012-11-20pcmdec: use planar sample format for pcm_s16le_planarJustin Ruggles
2012-11-01lavc: move SANE_NB_CHANNELS to internal.h and use it in the PCM decodersJustin Ruggles
2012-10-22pcm: define AVCodec instances only for enabled codecsMans Rullgard
This defines an AVCodec only if the corresponding CONFIG option is enabled instead of using the broad CONFIG_ENCODERS/DECODERS. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-10-12Move av_reverse table to libavcodecDiego Biurrun
It is only used in that library.
2012-10-09pcmdec: use planar sample format for pcm_lxfJustin Ruggles
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2012-05-17pcmenc: set correct bitrate valueMans Rullgard
This fixes a bogus bitrate value in the header of WAV files with alaw/ulaw audio. Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-04-04pcm: K&R formatting cosmeticsAneesh Dogra

2012-02-25check for coded_frame allocation failure in several audio encodersJustin Ruggles
2012-02-25audio encoders: do not set coded_frame->key_frame.Justin Ruggles
it is already set in avcodec_alloc_frame()
2012-02-02pcmenc: Do not set avpkt->size.Justin Ruggles
It is already the correct size as set by ff_alloc_packet().
2012-01-16pcmenc: use AVCodec.encode2()Justin Ruggles
2012-01-16avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio()Justin Ruggles
This allows audio encoders to optionally take an AVFrame as input and write encoded output to an AVPacket. This also adds AVCodec.encode2() which will also be usable by video and subtitle encoders once support is implemented in the public functions.
2012-01-11pcmenc: set frame_size to 0.Justin Ruggles
This indicates that the actual frame size is based on the buf_size passed to avcodec_encode_audio().
2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
2011-11-24pcmdec: remove unneeded resetting of samples pointerJustin Ruggles
2011-10-26pcmdec: fix output buffer size check by calculating the actual output sizeJustin Ruggles
prior to decoding.
2011-10-26pcmdec: move codec-specific variable declarations to the corresponding codecJustin Ruggles
blocks.
2011-10-26pcmdec: return buf_size instead of src-buf.Justin Ruggles
The values will always be the same, so this change eliminates an unneeded variable. It also gets rid of the need to reset src when memcpy() is used.
2011-10-26avcodec: remove the Zork PCM encoder.Justin Ruggles
The Zork PCM decoder does not decode the 1 sample we have correctly, therefore the encoder based on the decoder is also incorrect. There is no good reason to keep the encoder.
2011-10-26pcm_zork: use AV_SAMPLE_FMT_U8 instead of shifting all samples by 8.Justin Ruggles
2011-10-26pcmenc: remove unneeded sample_fmt check.Justin Ruggles
It is already checked by avcodec_open2().
2011-10-26pcmdec: move number of channels check to pcm_decode_init()Justin Ruggles
2011-10-26pcmdec: remove unnecessary check for sample_fmt changeJustin Ruggles
2011-10-26pcmdec: move DVD PCM bits_per_coded_sample check near to the code that setsJustin Ruggles
the sample size.
2011-10-26pcmdec: do not needlessly set *data_size to 0Justin Ruggles
2011-10-13pcm: reduce pointer type castingMans Rullgard
Making 'samples' a pointer to uint8_t simplifies the DECODE macro and reduces the amount of type casting overall. This also fixes some signed overflows on left shift. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-07-03Remove statements immediately following unconditional jumpsMans Rullgard
This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-04-19pcm: Add const to cast in ENCODE macro.Diego Biurrun
This fixes a lot of warnings of the sort: libavcodec/pcm.c:105: warning: cast discards qualifiers from pointer target type
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-02-11Remove final semicolon from some macrosMans Rullgard
This avoids double semicolons after macro expansion. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-01-25Don't declare a pcm_dvd encoder.Diego Elio Pettenò
The PCM_DVD encoder would be left unused, as allcodecs.c properly declared it as being decoder-only, but it would still be built into the object file. Since there is no block of code to properly encode this PCM format, it's not a full codec. Signed-off-by: Mans Rullgard <mans@mansr.com>
