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
Justin Ruggles	a1977e0103	lavc: shrink encoded audio packet size after encoding.	13 years ago
Ronald S. Bultje	c346f6304c	adpcm: fix nb_samples rounding for adpcm_ima_dk3, and update reference.	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
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
Anton Khirnov	eb727387fd	lavc: shrink encoded video packet size after encoding. Based on a patch by Nicolas George <nicolas.george <at> normalesup.org>	13 years ago
Diego Biurrun	d10319d87f	avcodec_default_reget_buffer(): fix compilation in DEBUG mode	13 years ago
Anton Khirnov	03ca0a5b30	lavc: merge two if()s with the same condition.	13 years ago
Anton Khirnov	d55fa6f9cb	lavc: factorize setting got_packet_ptr in avcodec_encode_video2()	13 years ago
Anton Khirnov	52953d61ca	lavc: signal no output when a NULL frame is passed to audio encoder without delay	13 years ago
Ronald S. Bultje	87840eeb71	avcodec: disallow reget_buffer() if pix_fmt changed.	13 years ago
Anton Khirnov	ff311c0918	lavc: drop encode() support for video. All video encoders have been converted to encode2(), all new encoders should also use only encode2().	13 years ago
Justin Ruggles	70749c483c	avcodec: do not override pts or duration from the audio encoder This allows encoders to set pts and/or duration even if they do not use CODEC_CAP_DELAY.	13 years ago
Justin Ruggles	91a28b0e8e	avcodec: add ff_samples_to_time_base() convenience function to internal.h	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Paul B Mahol	dcd2b55e1a	Check AVCodec.pix_fmts in avcodec_open2() Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	b758cf7343	avcodec: set avpkt->size to 0 if encode2() did not output a packet	13 years ago
Justin Ruggles	a75bc764ec	avcodec: for audio encoding, set packet dts to packet pts. There are no audio encoders which do frame reordering.	13 years ago
Anton Khirnov	52f82a1148	lavc: add avcodec_encode_video2() that encodes from an AVFrame -> AVPacket Deprecate avcodec_encode_video().	13 years ago
Ronald S. Bultje	9b027c0d07	dsputil: set STRIDE_ALIGN to 16 for x86 also. This fixes crashes in e.g. PNG decoding with SSE2 enabled. In fact, many x86 optimizations for codecs assume that our buffer strides are 16-byte aligned.	13 years ago
Justin Ruggles	1a670973a7	ff_alloc_packet: modify the size of the packet to match the requested size This will simplify encoders which use this function to request the exact packet size rather than the maximum size.	13 years ago
Janne Grunau	316fc7443b	avcodec: Add av_fast_padded_malloc(). Wrapper around av_fast_malloc() that keeps FF_INPUT_BUFFER_PADDING_SIZE zero-padded bytes at the end of the used buffer. Based on a patch by Reimar Döffinger <Reimar.Doeffinger@gmx.de>.	13 years ago
Anton Khirnov	bc90199848	lavc: set AVCodecContext.codec in avcodec_get_context_defaults3(). This way, if the AVCodecContext is allocated for a specific codec, the caller doesn't need to store this codec separately and then pass it again to avcodec_open2(). It also allows to set codec private options using av_opt_set_* before opening the codec.	13 years ago
Anton Khirnov	0e72ad95f9	lavc: make avcodec_close() work properly on unopened codecs. I.e. free the priv_data and other stuff allocated in avcodec_alloc_context3() and not segfault.	13 years ago
Anton Khirnov	af08d9aeea	lavc: add avcodec_is_open(). It allows to check whether an AVCodecContext is open in a documented way. Right now the undocumented way this check is done in lavf/lavc is by checking whether AVCodecContext.codec is NULL. However it's desirable to be able to set AVCodecContext.codec before avcodec_open2().	13 years ago
Anton Khirnov	2d9535ad31	avcodec_align_dimensions2: set only 4 linesizes, not AV_NUM_DATA_POINTERS. This function is video-only, so there's no point in setting more linesizes. Fixes stack corruption in avplay.	13 years ago
Martin Storsjö	9a7dc618c5	libavcodec: Don't crash in avcodec_encode_audio if time_base isn't set Earlier, calling avcodec_encode_audio worked fine even if time_base wasn't set. Now it crashes due to trying to scale the output pts to the codec context time base. This affects e.g. VLC. If no time_base is set for audio codecs, set it to the sample rate.

Anton Khirnov	284e65d64e	lavc: remove disabled FF_API_OLD_SAMPLE_FMT cruft.	13 years ago
Justin Ruggles	220506d23f	avcodec: add a new codec_id for CRYO APC IMA ADPCM. The stereo layout and extradata is significantly different from that in Westwood IMA ADPCM, so a separate codec_id is warranted.	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	5ee5fa021f	avcodec: add a public function, avcodec_fill_audio_frame(). This is a convenience function for the user to fill audio AVFrame information.	13 years ago
Reinhard Tartler	e2ff436ef6	lavc: Relax API strictness in avcodec_decode_audio3 with a custom get_buffer() Do not fail audio decoding with avcodec_decode_audio3 if user has set a custom get_buffer. Strictly speaking, this was never allowed by the API, but it seems that some software packages did so anyways. In order to unbreak applications (cf. http://bugs.debian.org/655890), this change clarifies the API and overrides the custom get_buffer() with the defaults. This change is inspired by a similar commit (`c3846e3eba`) in FFmpeg. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Alex Converse	4df30f7114	utils: Check for extradata size overflows.	13 years ago
Martin Storsjö	c5d907b6b0	libavcodec: Handle param change side data in avcodec_decode_video2, too Also call avcodec_set_dimensions on dimension param change packets. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	867f923df4	libavcodec: Move apply_param_change up above avcodec_decode_video2 This is in preparation to calling it from avcodec_decode_video2. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Janne Grunau	b6064d9a59	threads: set thread_count to 1 when thread support is disabled	13 years ago
Stefano Sabatini	8a4a5f6ff7	lavc: add format field to AVFrame The format is a per-frame property, having it in AVFrame simplify the operation of extraction of that information, since avoids the need to access the codec/stream context.	13 years ago
Stefano Sabatini	3a2ddf7c2c	lavc: add width and height fields to AVFrame width and height are per-frame properties, setting these values in AVFrame simplify the operation of extraction of that information, since avoids the need to check the codec/stream context.	13 years ago
Stefano Sabatini	b58dbb5b03	lavc: add a sample_aspect_ratio field to AVFrame The sample aspect ratio is a per-frame property, so it makes sense to define it in AVFrame rather than in the codec/stream context. Simplify application-level sample aspect ratio information extraction, and allow further simplifications.	13 years ago
Martin Storsjö	f13db94d0a	libavcodec: Apply parameter change side data when decoding audio Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Rafaël Carré	37c0dc626d	lavc: always align height by 32 pixel Interlaced content for most codec requires it. This patch is a stop-gap pending a serious rework to support codecs with non 16 pixel macroblocks. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Mans Rullgard	8400b126ac	avcodec: deprecate AVFrame.age This was intended as an optimisation for skipped blocks in MPEG2 P-frames and never used elsewhere. Removing this "optimisation" speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
