Martin Storsjö	3641b0489c	Add support for iLBC decoding/encoding via the external library libilbc The library is 3-clause BSD licensed. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Stefano Sabatini	3cc1a89881	lavc/utils: in avcodec_decode_video2() return proper error code instead of -1 Return AVERROR(EINVAL) in case of invalid coded size.	13 years ago
Michael Niedermayer	dded4cb20b	lavc: fix support of unofficial pix_fmt extensions of jpeg Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	62b39d41cd	lavc: add pkt_duration field to AVFrame	13 years ago
Michael Niedermayer	a5ad3c2382	av_get_audio_frame_duration: fix FPE Fixes ticket1392 Found-by: Piotr Bandurski <ami_stuff@o2.pl> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Lou Logan	73f3f6baff	lavc: clarify experimental codec message Should be easier for new users to get a working output. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	67b7631040	lavc: prettify printing of some codec tags which contains non alphanumeric characters Make av_get_codec_tag_string() show codec tag string characters in a more intelligible ways. For example the ascii char "@" is used as a number, so should be displayed like "[64]" rather than as a printable character. Apart alphanumeric chars, only the characters ' ' and '.' are used literally in codec tags, all the other characters represent numbers.	13 years ago
Michael Niedermayer	a1bb0823a9	libavcodec: correct consumed bytes for decoders Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	0c517644b2	avcodec/utils: cast a function argument to shut up a compiler warning libavcodec/utils.c:251: note: expected ‘const uint8_t ’ but argument is of type ‘const short int ’	13 years ago
Michael Niedermayer	8ea5df4fac	lavc/utils: fix division by 0 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	c22953b8a3	lavc: check that extended_data is properly set in avcodec_encode_audio2().	13 years ago
Anton Khirnov	a5117a2444	lavc: pad last audio frame with silence when needed.	13 years ago
Carl Eugen Hoyos	143a5c55ff	Add yuva422p pix_fmt.	13 years ago
Michael Niedermayer	011004152f	lavc/utils: change a few asserts to av_assert0() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	f132248028	avcodec: do not needlessly set packet size to 0 in avcodec_encode_audio2() It is already set to 0 by av_free_packet()	13 years ago
Justin Ruggles	74e10b6204	avcodec: for audio encoding, reset output packet when it is not valid	13 years ago
Justin Ruggles	fa0319b4fd	avcodec: refactor avcodec_encode_audio2() to merge common branches	13 years ago
Justin Ruggles	b461cd4deb	avcodec: remove fallbacks for AVCodec.encode() in avcodec_encode_audio2() We no longer have any audio encoders using AVCodec.encode().	13 years ago
Anton Khirnov	828bd088f3	lavc: add sample rate and channel layout to AVFrame. Rationale is the same as for video width/height etc.	13 years ago
Nicolas George	e296f1b1c4	lavc: implement accessors for some AVFrame fields. Compared to av_opt_ptr, accessors bring: - better performance (negligible); - compile-time type check; - link-time existence check (or at worst, a dynamic linker error instead of a NULL dereference).	13 years ago
Nicolas George	128dda7016	lavc: add a sample_rate field to AVFrame. The field is filled with the codec context information.	13 years ago
Nicolas George	4b0521eca9	lavc: add a channel_layout field to AVFrame. The field is filled with the codec context information. FIXME need a minor version bump.	13 years ago
Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Robert Nagy	c58290e5e5	Reset pts_correction state on codec flush. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	df8d5eaa14	avcodec_string: Favor AVCodecContext.codec over the default codec. This improves output for formats with more than one AVCodec.	13 years ago
Justin Ruggles	c58846f3a8	avcodec: use align == 0 for default alignment in avcodec_fill_audio_frame() Use default alignment in audio_get_buffer()	13 years ago
Justin Ruggles	1337de0c4b	avcodec: validate the channel layout vs. channel count for decoders Set avctx->channel_layout to 0 if the channel count does not match avctx->channels.	13 years ago
Reimar Döffinger	069cf86d32	Fix side-data memleak also for audio. This uses the same code as in decode_video also in decode_audio. Should fix valgrind FATE failures for nellymoser encode test. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Michael Niedermayer	7c9d69360c	lavc: check media type of the decoder before calling it. This fixes a segfault where a video decoder was called from avcodec_decode_audio*(). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	3c6607eb6f	avcodec_encode_{audio,video}: only reallocate output packet when it has non-zero size. Otherwise realloc would free it, which would result in double free later.	13 years ago
Ronald S. Bultje	bc1ef85520	lavc/avconv: support changing frame sizes in codecs with frame mt. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Michael Niedermayer	59a4b73531	pthread/mpegvideo: detect and block attempts to init frames after setup. This fixes race conditions that ultimately lead to memory corruption. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	532f1c7aa7	lavc: limit realloc() on encoding to the libav compatibility API. Neither the old nor new need it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	740b9ff44e	lavc: Redesign the internal encoding API. The new API allows (optionally and on by default) using a internal buffer to encode, avoiding the need to allocate large buffers or risking failure on too small buffers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	dca0e4cd61	avcodec_encode_audio2: use ff_alloc_packet2() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	00663de3b7	lavc: add ff_alloc_packet2(). This contains a AVCodecContext thus allowing us to prevent the error message duplication Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	6c9db40205	avcodec_encode_audio2: add missing padding to realloc() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	a1977e0103	lavc: shrink encoded audio packet size after encoding.	13 years ago
Michael Niedermayer	fc8ed1117e	avcodec_encode_audio2: Increase the audio buffer size. Fixes Ticket1104 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	c346f6304c	adpcm: fix nb_samples rounding for adpcm_ima_dk3, and update reference.	13 years ago
Nicolas George	15d75dabee	lavc/utils: fix three const warnings. No change in assembly code produced on x86_64.	13 years ago
Michael Niedermayer	57986c501e	lavc/utils: fix const correctness of AVClass cast Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	11344792e8	lavc/utils: remove unused variable from avcodec_encode_video2. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	9524cf79df	avcodec: add av_get_audio_frame_duration() function. This is a utility function for the user to get the frame duration based on the codec id, frame size in bytes, and various AVCodecContext parameters.	13 years ago
Justin Ruggles	6699d07480	avcodec: add av_get_exact_bits_per_sample() function This only returns bits per sample when it is exactly correct. That is, the codec contains only raw samples with no frame headers or padding. This applies to basically all PCM codecs and a small subset of ADPCM codecs.	13 years ago
Anton Khirnov	44fe77b350	lavc: make codec_is_decoder/encoder() public.	13 years ago
Nicolas George	b2792a436b	lavc: unify similar code merged from both branches.	13 years ago
Anton Khirnov	7fb6c9225c	lavc: free the output packet when encoding failed or produced no output.	13 years ago
Anton Khirnov	e42e9b0e4d	lavc: preserve avpkt->destruct in ff_alloc_packet(). Also, don't bother with saving/restoring data, av_init_packet doesn't touch it.	13 years ago
