* avcodec: Define side data type for fallback trackJohn Stebbins2015-11-18
| | | | | | | | | This side data type is meant to be added to AVStream side data. A fallback track indicates an alternate track to use when the current track can not be decoded for some reason. e.g. no decoder available for codec. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* avpacket: Provide an alloc and a free function for the structLuca Barbato2015-10-26
| | | | | Pave the way for having the size of the AVPacket struct not part of the ABI.
* avpacket: Deprecate av_dup_packetLuca Barbato2015-10-26
| | | | | As documented, `av_dup_packet` is broken by design, `av_packet_ref` matches the AVFrame ref-counted API and can be safely used instead.
* avpacket: Replace av_free_packet with av_packet_unrefLuca Barbato2015-10-26
| | | | | | | `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.
* lavc: Add data and linesize to AVSubtitleRectVittorio Giovara2015-10-21
| | | | | | | | | | | | Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | av_dict_set() could return an error, so forward it appropriately. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* lavc: Make AVPacket.duration int64, and deprecate convergence_durationwm42015-09-29
| | | | | | | | | Note that convergence_duration had another meaning, one which was in practice never used. The only real use for it was a 64 bit replacement for the duration field. It's better just to make duration 64 bits, and to get rid of it. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* lavu: Remove bit packing from AVComponentDescriptorVittorio Giovara2015-09-07
| | | | | | | | | There is no practical benefit in having this structure elements bit packed given the size of the structure and its usage. Change types from uint16_t (packed) to plain int in order to simplify modifying the structure and accessing its fields. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* Add a quality factor packet side dataVittorio Giovara2015-07-20

* lavu: add an API function to return the Libav version stringwm42015-07-02
| | | | | | | | This returns something like "v12_dev0-1332-g333a27c". This is much more useful than the individual library versions, of which there are too many, and which are very hard to map back to releases or git commits. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

* vda: Make output CVPixelBuffer format configurableStefano Pigozzi2015-05-13
| | | | | | | This is useful for client programs to ask for nv12 surfaces instead of the current default (uyvy), since those are more efficient to decode to. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* Add a side data type for audio service type.Anton Khirnov2015-01-27
| | | | | Currently, audio service type is a field in AVCodecContext. However, side data is more appropriate for this kind of information.
* imgutils: create misc functions for dealing with buffersStefano Sabatini2015-01-14
| | | | | | | | | | | | | | | | | Move the lavc/imgconvert functions and rename them as follows: avpicture_get_size -> av_image_get_buffer_size() avpicture_fill -> av_image_fill_arrays() avpicture_layout -> av_image_copy_to_buffer() The new functions have an align parameter, which allows to define the linesize alignment assumed in the buffer (which is set or read). The names of the functions are consistent with the lavu/samples API (av_samples_get_buffer_size(), av_samples_fill_arrays()). A redundant check has been dropped from av_image_fill_arrays().

* vdpau: add helper for surface chroma type and sizeRémi Denis-Courmont2014-12-25
| | | | | | | | | | | | | | | | | | | | | Since the VDPAU pixel format does not distinguish between different VDPAU video surface chroma types, we need another way to pass this data to the application. Originally VDPAU in libavcodec only supported decoding to 8-bits YUV with 4:2:0 chroma sampling. Correspondingly, applications assumed that libavcodec expected VDP_CHROMA_TYPE_420 video surfaces for output. However some of the new HEVC profiles proposed for addition to VDPAU would require different depth and/or sampling: http://lists.freedesktop.org/archives/vdpau/2014-July/000167.html ...as would lossless AVC profiles: http://lists.freedesktop.org/archives/vdpau/2014-November/000241.html To preserve backward binary compatibility with existing applications, a new av_vdpau_bind_context() flag is introduced in a further change.

* libavcodec: add AV_HWACCEL_ALLOW_HIGH_DEPTH flagRémi Denis-Courmont2014-12-25
| | | | | | | | This can be used by the application to signal its ability to cope with video surface of types other than 8-bits YUV 4:2:0. Signed-off-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* avcodec: add AVCodecContext.sw_pix_fmtRémi Denis-Courmont2014-12-25
| | | | | | | | 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>

* lavf: Add an option for avoiding negative timestampsMichael Niedermayer2014-11-07
| | | | | | | | | | | This is the same logic as is invoked on AVFMT_TS_NEGATIVE, but which can be enabled manually, or can be enabled in muxers which only need it in certain conditions. Also allow using the same mechanism to force streams to start at 0. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavc: add a public API for parsing vorbis packets.Anton Khirnov2014-11-06
| | | | | | It is required by (at least) the ogg demuxer. Mark the current semi-public apriv API for removal.
* lavu: Add av_gettime_relativeMartin Storsjö2014-10-24
| | | | | | | | | | | | | | | | | | | Since av_gettime() is used in a number of places where actual real time clock is required, the monotonic clock introduced in ebef9f5a5 would have consequences that are hard to handle. Instead split it into a separate function that can be used in the cases where only relative time is desired. On platform where no monotonic clock is available, the difference between the two av_gettime functions is not clear, and one could mistakenly use the relative clock where an absolute one is required. Therefore add an offset, to make it evident that the time returned from av_gettime_relative never is actual current real time, even though it is based on av_gettime. Based on a patch by Olivier Langlois. 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.
