* doc/APIchanges: fill in missing dates and hashesAnton Khirnov2015-02-13
| | | | Also, move a misplaced block to the right position.
* ogg: Provide an option to offset the serial numberLuca Barbato2015-02-01
| | | | | The ogg serial number doubles as codec id and sequence value for concatenated samples.
* 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.
* movenc: Add a flag for using default-base-is-moof in tfhd atomsMartin Storsjö2014-10-29
| | | | | | | | | | | | Similarly to the omit_tfhd_offset flag added in e7bf085b, this avoids writing absolute byte positions to the file, making them more easily streamable. This is a new feature from 14496-12:2012, so application support isn't necessarily too widespread yet (support for it in libav was added in 20f95f21f in July 2014).

| | | | Make it more structured.
* 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>
* hlsenc: Add parameter -hls_allow_cacheJoakim Roubert2014-10-03
| | | | | | | | | | | | | The -hls_allow_cache parameter enables explicitly setting the EXT-X-ALLOW-CACHE tag in the manifest file. That tag indicates whether the client MAY or MUST NOT cache downloaded media segments for later replay. Valid values are 1 (=YES) or 0 (=NO) and the EXT-X-ALLOW-CACHE will not show in the manifest for other values (or if -hls_allow_cache is not used. Signed-off-by: Martin Storsjö <martin@martin.st>

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().
