* 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.
* lavf: add AVFMT_FLAG_BITEXACT.Anton Khirnov2014-05-15
| | | | | | | | Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's codec context. Using codec options inside lavf is fragile and can easily break when the muxing codec context is not the encoding context.
* lavu: Add a pixel format for new VDA hwaccelAnton Khirnov2014-05-11
| | | | | The current hwaccel is broken and cannot be fixed in a compatible way. It will be deprecated and replaced with a new one.

* lavc: deprecate CODEC_FLAG_INPUT_PRESERVEDAnton Khirnov2014-05-01
| | | | The addition of reference-counted frames makes it pointless.
* dxva2_h264: add a workaround for old Intel GPUsHendrik Leppkes2014-04-28
| | | | | | | | | | Old Intel GPUs expect the reference frame index to the actual surface, instead of the index into RefFrameList as specified by the spec. This workaround should be set when using one of the "ClearVideo" decoder devices. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* avutil: Add av_get_time_base_q()Derek Buitenhuis2014-04-22
| | | | | | | | This fixes usage of AV_TIME_BASE_Q in C++ applications, which cannot use compound literals directly in their code. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* replaygain: correctly parse peak valuesAlessandro Ghedini2014-04-04
| | | | | | | | | | | | | | | According to the ReplayGain spec, the peak amplitude may overflow and may result in peak amplitude values greater than 1.0 with psychoacoustically coded audio, such as MP3. Fully compliant decoders must allow peak overflows. Additionally, having peak values in the 0<->UINT32_MAX scale makes it more difficult for applications to actually use the peak values (e.g. when implementing clipping prevention) since values have to be rescaled down. This patch corrects the peak parsing by removing the rescaling of the decoded values between 0 and UINT32_MAX and the 1.0 upper limit. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* lavf: improve handling of sparse streams when muxingLuca Barbato2014-02-04
| | | | | | | | | | | | | | | | | | Currently ff_interleave_packet_per_dts() waits until it gets a frame for each stream before outputting packets in interleaved order. Sparse streams (i.e. streams with much fewer packets than the other streams, like subtitles or audio with DTX) tend to add up latency and in specific cases end up allocating a large amount of memory. Emit the top packet from the packet_buffer if it has a time delta larger than a specified threshold. Original report of the issue and initial proposed solution by mus.svz@gmail.com.

* Bump major of libavfilter for reference counted buffer API changes.Reinhard Tartler2013-12-14
| | | | | | | | | | Applications that have been linked against an older release of Libav and pick up updated libraries experience segmentation faults because they pick up the new libavfilter, which assumes AVFrames have been allocated by libavutil and thus contain new reference-counting related fields. This will break for AVFrames that have been allocated by old libavcodec. All scheduled API changes are deferred to the next bump.
* Bump libavutil major version to account for the LLS API/ABI changes.Reinhard Tartler2013-12-14
| | | | | | | | Commit 41578f70cf8aec8e7565fba1ca7e07f3dc46c3d2 changed the LLS API, which was called from libavcodec. Thus using an old libavcodec with a new libavutil will break. All scheduled API changes are deferred to the next bump.
* lavc: deprecate avcodec_get_frame_defaults().Anton Khirnov2013-12-11
| | | | | Also bump libavcodec micro and add an APIchanges entry saying that av_frame_* should now be used instead of the lavc AVFrame functions.
