* 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>
* avutil/frame: Treat frame as uninitialized in get_frame_defaults()Andreas Rheinhardt2021-12-05
| | | | | | | | | | | | | | Currently, it also tests whether extended_data points to something different than the AVFrame's data array and frees extended_data if it is different. Yet this is only necessary for one of its three callers, namely av_frame_unref(); meanwhile the other two callers took measures to avoid this (or rather, to make it to an av_free(NULL)). This commit moves this chunk to av_frame_unref() (so that get_frame_defaults() now treats its input as uninitialized) and removes the now superfluous code in the other two callers.

* 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>

| * AVFrame: add an opaque_ref fieldwm42017-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | avutil/pixdesc: deprecate AV_PIX_FMT_FLAG_PSEUDOPALwm42018-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PSEUDOPAL pixel formats are not paletted, but carried a palette with the intention of allowing code to treat unpaletted formats as paletted. The palette simply mapped the byte values to the resulting RGB values, making it some sort of LUT for RGB conversion. It was used for 1 byte formats only: RGB4_BYTE, BGR4_BYTE, RGB8, BGR8, GRAY8. The first 4 are awfully obscure, used only by some ancient bitmap formats. The last one, GRAY8, is more common, but its treatment is grossly incorrect. It considers full range GRAY8 only, so GRAY8 coming from typical Y video planes was not mapped to the correct RGB values. This cannot be fixed, because AVFrame.color_range can be freely changed at runtime, and there is nothing to ensure the pseudo palette is updated. Also, nothing actually used the PSEUDOPAL palette data, except xwdenc (trivially changed in the previous commit). All other code had to treat it as a special case, just to ignore or to propagate palette data. In conclusion, this was just a very strange old mechnaism that has no real justification to exist anymore (although it may have been nice and useful in the past). Now it's an artifact that makes the API harder to use: API users who allocate their own pixel data have to be aware that they need to allocate the palette, or FFmpeg will crash on them in _some_ situations. On top of this, there was no API to allocate the pseuo palette outside of av_frame_get_buffer(). This patch not only deprecates AV_PIX_FMT_FLAG_PSEUDOPAL, but also makes the pseudo palette optional. Nothing accesses it anymore, though if it's set, it's propagated. It's still allocated and initialized for compatibility with API users that rely on this feature. But new API users do not need to allocate it. This was an explicit goal of this patch. Most changes replace AV_PIX_FMT_FLAG_PSEUDOPAL with FF_PSEUDOPAL. I first tried #ifdefing all code, but it was a mess. The FF_PSEUDOPAL macro reduces the mess, and still allows defining FF_API_PSEUDOPAL to 0. Passes FATE with FF_API_PSEUDOPAL enabled and disabled. In addition, FATE passes with FF_API_PSEUDOPAL set to 1, but with allocation functions manually changed to not allocating a palette.
* | 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).
