Anton Khirnov	669cc0f364	lavc: fix get_buffer() compatibility layer for audio. planes - FF_ARRAY_ELEMS would be evaluated as unsigned and underflow instead of being negative as was intended.	12 years ago
Anton Khirnov	0f24a3ca99	lavc: remove disabled FF_API_OLD_ENCODE_VIDEO cruft	12 years ago
Anton Khirnov	f073b1500e	lavc: remove disabled FF_API_OLD_ENCODE_AUDIO cruft	12 years ago
Anton Khirnov	5d606863c3	lavc: remove disabled FF_API_OLD_DECODE_AUDIO cruft	12 years ago
Anton Khirnov	7c45087b84	lavc: update the fallback versions of ff_thread_* Fixes build without threads after `759001c534`.	12 years ago
Anton Khirnov	2eba9087f3	lavc: make up a fake frame channel layout when there is no real one. This should ensure that a valid channel layout is always set on a frame, until a better solution is implemented.	12 years ago
Anton Khirnov	15ec0450b4	lavc: allow decoders to override frame parameters.	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	12 years ago
Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago
Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Stefano Sabatini	70762508ec	lavc: Prettify printing of codec tags containing 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. This also avoids relying on locale-dependent character class functions. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	d2a25c4032	get_buffer(): do not initialize the data. There may be more decoders that rely on this. Those should be found and fixed.	12 years ago
Diego Biurrun	c6507946d4	dsputil: Move STRIDE_ALIGN macro to the only place it is used	12 years ago
Luca Barbato	bff3607547	lavc: set the default rc_initial_buffer_occupancy rc_buffer_size is not set before. Solve the initial the rate control underflow issue reported in bug 222. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Diego Biurrun	015da965a6	libavcodec/utils: Add braces to shut up gcc warnings libavcodec/utils.c:1050:5: warning: missing braces around initializer [-Wmissing-braces] libavcodec/utils.c:1314:5: warning: missing braces around initializer [-Wmissing-braces]	12 years ago
Janne Grunau	bd255f9feb	lavc: set frame parameters after decoding only if necessary Direct rendering capable decoders call get_buffer() which will set the frame parameters. Prevents frames with wrong parameters when a decoder outputs delayed frames after a resolution or pixel format change.	12 years ago
Anton Khirnov	387bef95d2	lavc: factorise setting buffer type in avcodec_default_get_buffer().	12 years ago
Anton Khirnov	e57c4706e9	lavc: don't reuse audio buffers Any performance gain from this is negligible and not worth the extra code.	12 years ago
Anton Khirnov	ff953fecff	lavc: set frame properties in ff_get_buffer(). There is no point in duplicating this code in every get_buffer() implementation.	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
Luca Barbato	cc085993f4	avcodec: remove ff_is_hwaccel_pix_fmt It is used only in one place and is unlikely it would be needed elsewhere.	12 years ago
Luca Barbato	c1a02e884a	pixdesc: add av_pix_fmt_get_chroma_sub_sample Deprecate avcodec_get_chroma_sub_sample.	12 years ago
Justin Ruggles	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Ilkka Ollakka	6d1270a0f9	decode_audio3: initialize AVFrame Same fix and issue as in `a25d912dca` Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Justin Ruggles	0366664ef9	lavc: check channel count after decoder init Ensures the decoder did not set channel count to an insanely high value during initialization, which could cause large memory usage when it tries to get a buffer during decoding.	12 years ago
Justin Ruggles	bb6941af2a	lavc: move SANE_NB_CHANNELS to internal.h and use it in the PCM decoders	12 years ago
Anton Khirnov	1bc64c2814	lavc: initialize output AVFrame before decoding. Avoids memleaks with audio when extended_data is nontrivial and the user doesn't reset the frame. Shouldn't have any effect for video for now, but might be useful in the future.	12 years ago
Justin Ruggles	a5ef830b12	lavc: use the correct API version guard macro for avcodec_encode_audio()	12 years ago
Nathan Caldwell	c854102da7	avcodec: handle AVERROR_EXPERIMENTAL Error out on init if a codec with CODEC_CAP_EXPERIMENTAL is requested and strict_std_compliance is not FF_COMPLIANCE_EXPERIMENTAL. Move the check from avconv to avcodec_open2() and return AVERROR_EXPERIMENTAL accordingly. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Nathan Caldwell	a4aa20fbdb	avcodec: prefer decoders without CODEC_CAP_EXPERIMENTAL Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Rafaël Carré	a25d912dca	avcodec_encode_audio(): fix invalid free Since `2bc0de385`, AVFrame needs to be initialized before calling avcodec_get_frame_defaults(). Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Diego Biurrun	52d113ee06	avutil: Rename ff_set_systematic_pal2() ---> avpriv_set_systematic_pal2() Functions used across libraries should have avpriv_ and not ff_ prefixes.	12 years ago
Luca Barbato	6d5600e855	avutil: add yuva422p and yuva444p formats	12 years ago
Anton Khirnov	50ba57e0ce	lavc: do not use av_pix_fmt_descriptors directly.	12 years ago
Janne Grunau	3fbda309e5	avcodec: free extended_data instead address of it Fixes CID732173.	12 years ago
Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Justin Ruggles	37f701f1c3	avcodec: allow either planar or interleaved sample format when encoding mono When there is only 1 channel, the planar and interleaved formats of the same data type should be treated as identical.	12 years ago
Diego Biurrun	9c6cf7f2c9	avcodec: Drop silly and/or broken printf debug output	12 years ago
Anton Khirnov	12e1e83461	lavc: set channel count from channel layout in avcodec_open2(). Some decoders (e.g. nellymoser) only set channel_layout and do not set channel count.	12 years ago
Diego Biurrun	0ae3ba8daa	avcodec: Drop long-deprecated imgconvert.h header	12 years ago
Anton Khirnov	a42aadabc6	lavc: add avcodec_free_frame(). Since an AVFrame now has malloced members (extended_data), it must have a destructor.	12 years ago
Anton Khirnov	b437cec143	lavc: ensure extended_data is set properly on decoding	12 years ago
Anton Khirnov	2bc0de3858	lavc: initialize AVFrame.extended_data in avcodec_get_frame_defaults()	12 years ago
Anton Khirnov	c084a975aa	lavc: use av_mallocz to allocate AVFrames. Otherwise the frame is uninitialized, so avcodec_get_frame_defaults() cannot determine whether to free extended_data.	12 years ago
Anton Khirnov	a83499b13b	lavc: rename the argument of avcodec_alloc_frame/get_frame_defaults AVFrame is used for both audio and video, so calling the argument 'pic' is misleading.	12 years ago
Justin Ruggles	0ccf051a9d	avcodec: fix memleak in avcodec_encode_audio2() Ensure that padded_frame is freed before returning when needed.	13 years ago
Luca Barbato	419ffb2390	avcodec: cleanup utils.c	13 years ago
Anton Khirnov	466b39efaf	lavc: replace AVCodecContext.encode with subtitle-specific callback AVCodecContext.encode is currently used only for subtitles, encode2 is used for audio and video.	13 years ago
Anton Khirnov	9f64c8219a	lavc: add const to private codec class initialization. Silences a warning about discarding const.	13 years ago
