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
Aneesh Dogra	6d21f49879	pcm: K&R formatting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Paul B Mahol	ae2c33b0c2	cosmetics: remove superfluous curly brackets Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Paul B Mahol	32a5775a91	pcm: leave sample format conversion to libswresample Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Paul B Mahol	ae8dc203b2	pcm: check return value of avcodec_alloc_frame() 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
Daniel Kristjansson	f36ce75e35	pcm: Print number of bits in the error message of unsupported DVD PCM formats.	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	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	98ec828775	Remove final semicolon from some macros This avoids double semicolons after macro expansion. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `44adbebe17`)	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

Diego Elio Pettenò	11c7f64a9c	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> (cherry picked from commit `5b5083b5fe`)	14 years ago

Reimar Döffinger	edac49daf5	Use "const" qualifier for pointers that point to input data of audio encoders. This is purely for clarity/documentation purposes. Originally committed as revision 24481 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
