* Add a quality factor packet side dataVittorio Giovara2015-07-20
| | | | | | | | This is necessary to preserve the quality information currently exported with coded_frame. Add the new side data to every encoder that needs it, and use it in avconv. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* APIchanges: Mention lavfi and lavd identification symbol additionVittorio Giovara2015-07-17
|
* lavu: Add version information for av_version_info()Vittorio Giovara2015-07-03
| | | | Move the APIchange entry at the top.
* 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>
* avio: Add avio_put_str16beLuca Barbato2015-06-07

* 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>
* log: Introduce a more verbose debug levelVittorio Giovara2015-04-19
| | | | And deprecate av_dlog macro.
* parseutils: Make av_small_strptime publicLuca Barbato2015-04-07
| | | | | | And use it in libavformat. Based on a similar patch by Stefano Sabatini <stefasab@gmail.com>.

* pixfmt: add a pixel format for QSV hwaccelAnton Khirnov2015-02-19
|
* doc/APIchanges: fill in missing dates and hashesAnton Khirnov2015-02-13
| | | | Also, move a misplaced block to the right position.
* 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>
* APIchanges: mark the release 11 branch pointwm42014-12-03

* 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.

* 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>

* AVOption: add support for dictionary types.Andrew Stone2014-08-13
| | | | | | | In order to support metadata being set as an option, it's necessary to be able to set dictionaries as values. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* lavf: add AVFormatContext/AVStream fields for signaling to the user when ↵Andrew Stone2014-08-13
| | | | | | | | | | | events happen. The only flags, for now, indicate if metadata was updated and are set after each call to av_read_frame(). This comes with the caveat that, on stream start, it might not be set properly as packets might be buffered in AVFormatContext.packet_buffer before being given to the user in av_read_frame().

* avcodec: Rename xvidmmx IDCT to xvidDiego Biurrun2014-08-08
| | | | The Xvid IDCT is not MMX-specific.
* swscale: Undeprecate sws_getContext()Diego Biurrun2014-08-07
| | | | sws_getCachedContext is not a full replacement for the function.
* 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.

|
* avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara2014-08-04
| | | | | | | The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.
