* lavu/frame: allow calling av_frame_make_writable() on non-refcounted framesAnton Khirnov2022-08-02
| | | | | This is an easy way to make a refcounted frame from a non-refcounted one.
* lavu/frame: add a duration field to AVFrameAnton Khirnov2022-07-19
| | | | | | | | | The only duration field currently present in AVFrame is pkt_duration, which is semantically restricted to those frames that are output by decoders. Add a new field that stores the frame's duration without regard for how that frame was produced. Deprecate pkt_duration.

* lavu/frame: Add Dolby Vision metadata side data typeNiklas Haas2022-01-04
| | | | | | | | | | | In order to be able to extend this struct later (as the Dolby Vision RPU evolves), all of the 'container' structs are considered extensible, and the individual constituent fields must instead be accessed via offsets. The precedent for this style of access is set in <libavutil/detection_bbox.h> Signed-off-by: Niklas Haas <git@haasn.dev> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* lavu/frame: clarify doxyAnton Khirnov2021-12-04
| | | | | AVFrame.data[] elements not used by the format should ALWAYS be null, hwaccel formats are not an exception.
* lavu/frame: drop mentions of non-refcounted framesAnton Khirnov2021-12-04
| | | | All frames we deal with should always be refcounted now.
* lavu/avframe: add a time_base fieldLynne2021-12-03
| | | | | This adds a time_base field to AVFrame, as an analogue to the AVPacket.time_base field.

* avutil: add ROI (Region Of Interest) data struct and bump versionGuo, Yejun2019-01-17
| | | | | | | | | | | | | | | The encoders such as libx264 support different QPs offset for different MBs, it makes possible for ROI-based encoding. It makes sense to add support within ffmpeg to generate/accept ROI infos and pass into encoders. Typical usage: After AVFrame is decoded, a ffmpeg filter or user's code generates ROI info for that frame, and the encoder finally does the ROI-based encoding. The ROI info is maintained as side data of AVFrame. Signed-off-by: Guo, Yejun <yejun.guo@intel.com> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

| | | | | | | | The dynamic metadata contains data for color volume transform - application 4 of SMPTE 2094-40:2016 standard. The data comes from HEVC in the SEI_TYPE_USER_DATA_REGISTERED_ITU_T_T35. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* libavutil: Undeprecate the AVFrame reordered_opaque fieldMartin Storsjö2018-11-05
| | | | | | | | This was marked as deprecated (but only in the doxygen, not with an actual deprecation attribute) in 81c623fae05 in 2011, but was undeprecated in ad1ee5fa7. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavc/h264: create AVFrame side data from H.264 timecodesDevin Heitmueller2018-10-23
| | | | | | | | | Create SMPTE ST 12-1 timecodes based on H.264 SEI picture timing info. For framerates > 30 FPS, the field flag is used in conjunction with pairs of frames which contain the same frame timestamp in S12M. Ensure the field is properly set per the spec.
* lavu/frame: add QP side datawm42018-03-18
| | | | | | | | | | | | | | | | | | | This adds a way for an API user to transfer QP data and metadata without having to keep the reference to AVFrame, and without having to explicitly care about QP APIs. It might also provide a way to finally remove the deprecated QP related fields. In the end, the QP table should be handled in a very similar way to e.g. AV_FRAME_DATA_MOTION_VECTORS. There are two side data types, because I didn't care about having to repack the QP data so the table and the metadata are in a single AVBufferRef. Otherwise it would have either required a copy on decoding (extra slowdown for something as obscure as the QP data), or would have required making intrusive changes to the codecs which support export of this data. The new side data types are added under deprecation guards, because I don't intend to change the status of the QP export as being deprecated (as it was before this patch too).
* lavu/frame: fix inconsistent qp_table_buf deprecationwm42018-03-18
| | | | | | Everything related to the QP data is deprecated, with qp_table_buf being an inconsistent exception. Some parts were under the deprecation guards, some not. It probably didn't even compile.

| | | | | | | | | | | | | | | | | | | | Allow all struct fields to be accessed directly, as long as they're public. Before this change, many fields were "public", but could be accessed via AVOption only. This meant they were effectively not public, but were present for documentation purposes, which was incredibly confusing at best.
* | AVFrame: add an opaque_ref fieldwm42017-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit 04f3bd349651.
