* lavc: deprecate the use of AVCodecContext.time_base for decodingAnton Khirnov2014-10-15
| | | | | | | | | | | 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.
* vdpau: add AV_HWACCEL_FLAG_IGNORE_LEVEL to skip the codec level checkRémi Denis-Courmont2014-10-15
| | | | | | | | | | | | | Decoding acceleration may work even if the codec level is higher than the stated limit of the VDPAU driver. Or the problem may be considered acceptable by the user. This flag allows skipping the codec level capability checks and proceed with decoding. Applications should obviously not set this flag by default, but only if the user explicitly requested this behavior (and presumably knows how to turn it back off if it fails).

* lavc: use a separate field for exporting audio encoder paddingAnton Khirnov2014-10-13
| | | | | | | | | | | | | | 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.
* lavc: specify the behavior of av_lockmgr_register on failure.Manfred Georg2014-10-06
| | | | | | | | | | | 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).

* hwaccel: Call ->get_format again if hwaccel init failsRémi Denis-Courmont2014-09-26
| | | | | | | This allows the application to fall back on another hwaccel or, more likely, software decoding. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* avcodec: Rename xvidmmx IDCT to xvidDiego Biurrun2014-08-08
| | | | The Xvid IDCT is not MMX-specific.
* avcodec: Undeprecate reordered_opaqueDiego Biurrun2014-08-07
| | | | | | | It allows attaching other external, opaque data to the frame and passing it through the reordering process, for cases when the caller wants other data than just the plain packet pts. There is no way to cleanly achieve this without the field.

* lavc: add an option to enable side data-only packets during encodingAnton Khirnov2014-06-01
| | | | | | Some encoders (e.g. flac) need to send side data when there is no more data to be output. This enables them to output a packet with no data in it, only side data.

* Add transformation matrix API.Vittorio Giovara2014-05-19
| | | | | | | | | | | 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>
* lavc: add avcodec_free_context().Anton Khirnov2014-05-18
| | | | | | | | | | | Right now, the caller has to manually manage some allocated AVCodecContext fields, like extradata or subtitle_header. This is fragile and prone to leaks, especially if we want to add more such fields in the future. The only reason for this behaviour is so that the AVStream codec context can be reused for decoding. Such reuse is discouraged anyway, so this commit is the first step to deprecating it.
