* avcodec: add a new codec_id for CRYO APC IMA ADPCM.Justin Ruggles2012-01-24
| | | | | The stereo layout and extradata is significantly different from that in Westwood IMA ADPCM, so a separate codec_id is warranted.
* avcodec: Add avcodec_encode_audio2() as replacement for avcodec_encode_audio()Justin Ruggles2012-01-15
| | | | | | | | 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.
* avcodec: add a public function, avcodec_fill_audio_frame().Justin Ruggles2012-01-15
| | | | This is a convenience function for the user to fill audio AVFrame information.
* lavc: Relax API strictness in avcodec_decode_audio3 with a custom get_buffer()Reinhard Tartler2012-01-15
| | | | | | | | | | | | | 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 (c3846e3ebab610be691adb8b40d376dc2f675dc4) in FFmpeg. Signed-off-by: Reinhard Tartler <siretart@tauware.de>

* lavc: add format field to AVFrameStefano Sabatini2011-12-25
| | | | | | 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.
* lavc: add width and height fields to AVFrameStefano Sabatini2011-12-25
| | | | | | 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.
* lavc: add a sample_aspect_ratio field to AVFrameStefano Sabatini2011-12-25
| | | | | | | 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.

* lavc: always align height by 32 pixelRafaël Carré2011-12-21
| | | | | | | | 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>
* avcodec: deprecate AVFrame.ageMans Rullgard2011-12-18
| | | | | | | | 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>
* lavc: avoid invalid memcpy() in avcodec_default_release_buffer()Mans Rullgard2011-12-11
| | | | | | | | | | When the buf and last pointers are equal, the FFSWAP() results in an invalid call to memcpy() with same source and destination on some targets. Although assigning a struct to itself is valid C99, gcc does not check for this before calling memcpy(). See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32667 Signed-off-by: Mans Rullgard <mans@mansr.com>
* g722: Change bits per sample to 4Sjoerd Simons2011-12-05
| | | | | | | | | | | | | | | Earlier, bits per sample was defined as 8, since bits_per_coded_sample was used to indicate whether to ignore the lower bits of the codeword, having values 6, 7 or 8. g722 encodes 2 samples into one byte codeword, therefore the bits per sample is 4. By changing this, the generated timestamps for streams encoded with g722 become correct. This makes timestamp generation for g722 data correct (both when encoding and when demuxing from raw g722 files). Signed-off-by: Martin Storsjö <martin@martin.st>
* Add avcodec_decode_audio4().Justin Ruggles2011-12-02
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* avcodec: change number of plane pointers from 4 to 8 at next major bump.Justin Ruggles2011-12-02
| | | | | | Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.
* h264: add support for decoding planar RGB images.Ronald S. Bultje2011-11-24

* avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles2011-11-19
| | | | | | | | A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.
* avcodec: Allow locking and unlocking an avformat specific mutexMartin Storsjö2011-11-05
| | | | | | | This extends the lock manager in avcodec to manage two separate mutexes via the user-specified lock functions. Signed-off-by: Martin Storsjö <martin@martin.st>

* avcodec: reject audio packets with NULL data and non-zero sizeJustin Ruggles2011-09-30
| | | | | | | There is no valid reason the user should ever send such packets in the first place, but the documentation for CODEC_CAP_DELAY states that the codec is guaranteed not to get a NULL packet unless that capability is set. That isn't true without preventing this case.

* lavc: make avcodec_init() static on next bump.Anton Khirnov2011-08-10
| | | | | It's called from avcodec_register() anyway, so there's no reason for it to be public.

* Add the notion of pixel size in h264 related functions.Oskar Arvidsson2011-05-10
| | | | | | | | | | In high bit depth the pixels will not be stored in uint8_t like in the normal case, but in uint16_t. The pixel size is thus 1 in normal bit depth and 2 in high bit depth. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Add pixel formats for 9- and 10-bit yuv420p.Oskar Arvidsson2011-05-10

* If AVCodecContext.channels is 0 and AVCodecContext.channel_layout isJustin Ruggles2011-04-27
| | | | | | non-zero, set channels based on channel_layout. This allows the user to set only channel_layout and not channels.
