Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	d6604b29ef	Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago

Paul B Mahol	7e52080cb1	pcm: support 24-bit/32-bit little-endian planar Used by LXF. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Christian Schmidt	a42e3a6700	pcm_dvd: consolidate pieces from pcm.c and mpeg.c 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>	11 years ago
Luca Barbato	c82da343e6	pcm: always use codec->id instead of codec_id Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Justin Ruggles	a6bb39add2	pcm: decode directly to the user-provided AVFrame	12 years ago
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
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
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

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
Aneesh Dogra	6d21f49879	pcm: K&R formatting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	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
Justin Ruggles	3c432631e9	pcmenc: Do not set avpkt->size. It is already the correct size as set by ff_alloc_packet().	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
Mans Rullgard	b27565b143	Remove statements immediately following unconditional jumps This removes a number of compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	151cd4f982	pcm: Add const to cast in ENCODE macro. This fixes a lot of warnings of the sort: libavcodec/pcm.c:105: warning: cast discards qualifiers from pointer target type	14 years ago

Mans Rullgard	44adbebe17	Remove final semicolon from some macros This avoids double semicolons after macro expansion. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	d36beb3f69	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>	14 years ago
Diego Elio Pettenò	5b5083b5fe	Don't declare a pcm_dvd encoder. 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>	14 years ago
