Vittorio Giovara	40cf1bbacc	Deprecate avctx.coded_frame The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Vittorio Giovara	d6604b29ef	Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Paul B Mahol	5a79bf0284	PCM signed 16-bit big-endian planar decoder Signed-off-by: Paul B Mahol <onemda@gmail.com>	10 years ago
Luca Barbato	a78f5548d9	avcodec: Free the default avoptions on init failure	10 years ago
Luca Barbato	aef0be0875	avcodec: Unref the dummy buffer on the fail path	10 years ago
Vittorio Giovara	117b432748	lavc: Introduce AVCodec internal capabilities This field is designed for marking codec properties useful to lavc internals. Two internal capabilities are added: - FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks; - FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.	10 years ago

Andreas Cadhalpun	ea1d0b7ece	avcodec/utils: use correct printf specifier in ff_set_sar Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago
Anton Khirnov	a536a4e4bc	lavc: support extracting audio service type from side data	10 years ago
Anton Khirnov	728685f37a	Add a side data type for audio service type. Currently, audio service type is a field in AVCodecContext. However, side data is more appropriate for this kind of information.	10 years ago
Paul B Mahol	9a4aaae3b2	lavc: add GBRAP to avcodec_align_dimensions2	10 years ago
Rémi Denis-Courmont	57b6704ecd	avcodec: add AVCodecContext.sw_pix_fmt This carries the pixel format that would be used if it were not for hardware acceleration. This is equal to AVCodecContext.pix_fmt if hardware acceleration is not in use. Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago
Luca Barbato	e3e317e0c0	lavc: Compact the side-data passthrough	10 years ago
Rémi Denis-Courmont	4ff670d99b	hwaccel: Deinitialize hardware acceleration early enough The application will destroy the underlying hardware handles when get_format() gets called again. Also this ensures the deinitialization takes place if the get_format callback returns an error. Regression from `1c80c9d7ef`. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Vittorio Giovara	bae557edce	dump: display codec tags when available For both audio and video.	11 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	11 years ago
Anton Khirnov	2df0c32ea1	lavc: use a separate field for exporting audio encoder padding Currently, the amount of padding inserted at the beginning by some audio encoders, is exported through AVCodecContext.delay. However - the term 'delay' is heavily overloaded and can have multiple different meanings even in the case of audio encoding. - this field has entirely different meanings, depending on whether the codec context is used for encoding or decoding (and has yet another different meaning for video), preventing generic handling of the codec context. Therefore, add a new field -- AVCodecContext.initial_padding. It could conceivably be used for decoding as well at a later point.	11 years ago

Rémi Denis-Courmont	153fadc390	ff_get_format: fix infinite loop Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Manfred Georg	577899a645	lavc: specify the behavior of av_lockmgr_register on failure. The register function now specifies that the user callback should leave things in the same state that it found them on failure but that failure to destroy is ignored by the library. The register function is now explicit about its behavior on failure (it unregisters the previous callback and destroys all mutex).

Rémi Denis-Courmont	1c80c9d7ef	hwaccel: Call ->get_format again if hwaccel init fails This allows the application to fall back on another hwaccel or, more likely, software decoding. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

Vittorio Giovara	bddd8cbf68	Add transformation matrix API. Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and frame side data (respectively) to describe a display transformation matrix for linear transformation operations on the decoded video. Add functions to easily extract a rotation angle from a matrix and conversely to setup a matrix for a given rotation angle. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
