Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Michael Niedermayer	f0695b09dd	pcmdec: check codec_id Fixes out of array accesses Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Paul B Mahol	dd59f0125d	add some planar PCM encoders Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Paul B Mahol	f17f759544	pcmdec: use memcpy() when possible for planar decoders This is faster (at least with clang). Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Justin Ruggles	00dd9a6d6a	pcm: fix decoding of pcm_s16le_planar on big-endian 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.	12 years ago
Paul B Mahol	00e02366a5	pcmenc: use ENCODE macro for pcm_s8 Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Michael Niedermayer	2d232f8b88	pcm: revert from libavs planar code to durandals. The libav code does not work on big endian. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Paul B Mahol	da8242e2d6	8svx: move pcm_s8_planar decoder to pcm.c Removes limitation of max 2 channels for pcm_s8_planar decoder by moving it to more natural place. AV_CODEC_ID_8SVX_RAW is not used by anything anymore and is going to be removed. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Justin Ruggles	c9d0f4506f	pcmdec: use planar sample format for pcm_s16le_planar	12 years ago

Justin Ruggles	bb6941af2a	lavc: move SANE_NB_CHANNELS to internal.h and use it in the PCM decoders	12 years ago
Mans Rullgard	abdee95224	pcm: define AVCodec instances only for enabled codecs 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>	12 years ago
Diego Biurrun	d5c62122a7	Move av_reverse table to libavcodec It is only used in that library.	12 years ago

Stefano Sabatini	201b409da0	lavc/pcm: clarify error message from pcm_decode_frame() Extend/clarify an error message in case of invalid packet size, and return a proper error message instead of -1. Improve debuggability.	13 years ago
Mans Rullgard	7d7b40f48a	pcmenc: set correct bitrate value This fixes a bogus bitrate value in the header of WAV files with alaw/ulaw audio. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Justin Ruggles	a8bdf2405c	check for coded_frame allocation failure in several audio encoders	13 years ago
Justin Ruggles	255ad8881d	audio encoders: do not set coded_frame->key_frame. it is already set in avcodec_alloc_frame()	13 years ago
Stefano Sabatini	d21b82fd3a	lavc: provide aliases to the PCM A-law/mu-law codecs They are also known as G.711 codecs.	13 years ago
Justin Ruggles	3c432631e9	pcmenc: Do not set avpkt->size. It is already the correct size as set by ff_alloc_packet().	13 years ago
Paul B Mahol	1fa24d08b2	pcm: remove redundant assignment Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Justin Ruggles	05f95443ca	pcmenc: use AVCodec.encode2()	13 years ago
Justin Ruggles	b2c75b6e63	avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio() 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.	13 years ago
Justin Ruggles	56f22b7e16	pcmenc: set frame_size to 0. This indicates that the actual frame size is based on the buf_size passed to avcodec_encode_audio().	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	c1848c4b26	pcmdec: remove unneeded resetting of samples pointer	13 years ago
Justin Ruggles	f1901180e0	pcmdec: fix output buffer size check by calculating the actual output size prior to decoding.	13 years ago
Justin Ruggles	154cd253e5	pcmdec: move codec-specific variable declarations to the corresponding codec blocks.	13 years ago
Justin Ruggles	0093f96d34	pcmdec: return buf_size instead of src-buf. 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.	13 years ago
Justin Ruggles	85579b6381	avcodec: remove the Zork PCM encoder. 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.	13 years ago
Justin Ruggles	67a3b67c71	pcm_zork: use AV_SAMPLE_FMT_U8 instead of shifting all samples by 8.	13 years ago
Justin Ruggles	06af335a33	pcmenc: remove unneeded sample_fmt check. It is already checked by avcodec_open2().	13 years ago
Justin Ruggles	d94e29cac9	pcmdec: move number of channels check to pcm_decode_init()	13 years ago
Justin Ruggles	83efd7652e	pcmdec: remove unnecessary check for sample_fmt change	13 years ago
Justin Ruggles	381e195b46	pcmdec: move DVD PCM bits_per_coded_sample check near to the code that sets the sample size.	13 years ago
Justin Ruggles	6b94711f15	pcmdec: do not needlessly set *data_size to 0	13 years ago
Mans Rullgard	b45eb9d619	pcm: reduce pointer type casting 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>	13 years ago
