* libfdk-aacdec: Enable Dynamic Range Control Metadata SupportOmer Osman2014-10-17
| | | | | | | | | | For streams which contain DRC metadata, the FDK decoder is able to control rendering of the decoded output. The rendering parameters are detailed in fdk_aac_dec_options []. The default behavior is left up to the decoder. Signed-off-by: Martin Storsjö <martin@martin.st>
* libfdk-aacdec: Enable Decoder Downmix including Downmix Metadata SupportOmer Osman2014-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | The FDK decoder is capable of producing mono and stereo downmix from multichannel streams. These streams may contain metadata that control the downmix process. The decoder requires an Ancillary Buffer in order to correctly apply downmix in streams containing downmix Metadata. The decoder does not have an API interface to inform of the presence of Metadata in the stream, and therefore the Ancillary Buffer is always allocated whenever a downmix is requested. When downmixing multichannel streams, the decoder requires the output buffer in aacDecoder_DecodeFrame call to be of fixed size in order to hold the actual number of channels contained in the stream. For example, for a 5.1ch to stereo downmix, the decoder requires that the output buffer is allocated for 6 channels, regardless of the fact that the output is in fact two channels. Due to this requirement, the output buffer is allocated for the maximum output buffer size in case a downmix is requested (and also during decoder init). When a downmix is requested, the buffer used for output during init will also be used for the entire duration the decoder is open. Otherwise, the initial decoder output buffer is freed and the decoder decodes straight into the output AVFrame. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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).

* vdpau: add av_vdpau_bind_context()Rémi Denis-Courmont2014-10-06
| | | | | | | | | | | | This function provides an explicit VDPAU device and VDPAU driver to libavcodec, so that the application is relieved from codec specifics and VdpDevice life cycle management. A stub flags parameter is added for future extension. For instance, it could be used to ignore codec level capabilities (if someone feels dangerous). Signed-off-by: Anton Khirnov <anton@khirnov.net>

* vdpau: common support for managing the VdpDecoder in avcodecRémi Denis-Courmont2014-10-05
| | | | | | | | | | | | Using the not so new init and uninit callbacks, avcodec can now take care of creating and destroying the VDPAU decoder instance. The application is still responsible for creating the VDPAU device and allocating video surfaces - this is necessary to keep video surfaces on the GPU all the way to the output. But the application will no longer needs to care about any codec-specific aspects. Signed-off-by: Anton Khirnov <anton@khirnov.net>
