* avutil/film_grain_params: add av_film_grain_params_select()Niklas Haas2024-03-231-0/+3
| | | | | | | | Common utility function that can be used by all codecs to select the right (any valid) film grain parameter set. In particular, this is useful for AFGS1, which has support for multiple parameters. However, it also performs parameter validation for H274.
* avutil/film_grain_params: add metadata to common structNiklas Haas2024-03-231-0/+6
| | | | | | | | | | | | This is needed for AV1 film grain as well, when using AFGS1 streams. Also add extra width/height and subsampling information, which AFGS1 cares about, as part of the same API bump. (And in principle, H274 should also expose this information, since it is needed downstream to correctly adjust the chroma grain frequency to the subsampling ratio) Deprecate the equivalent H274-exclusive fields. To avoid breaking ABI, add the new fields after the union; but with enough of a paper trail to hopefully re-order them on the next bump.
* avcodec: add av_jni_{get,set}_android_app_ctx() helpersMatthieu Bouron2024-03-231-0/+3
| | | | | This will allow users to pass the Android ApplicationContext which is mandatory to retrieve the ContentResolver responsible to resolve/open Android content URIS.
* avutil/frame: Rename av_frame_side_data_get and add wrapper for itAndreas Rheinhardt2024-03-221-1/+4
| | | | | | | | | | | | | | | | | | | av_frame_side_data_get() has a const AVFrameSideData * const *sd parameter; so calling it with an AVFramesSideData **sd like AVCodecContext.decoded_side_data (or with a AVFramesSideData * const *sd) is safe, but the conversion is not performed automatically in C. All users of this function therefore resort to a cast. This commit changes this: av_frame_side_data_get() is renamed to av_frame_side_data_get_c(); furthermore, a static inline wrapper for it name av_frame_side_data_get() is added that accepts an AVFramesSideData * const * and converts this to const AVFramesSideData * const * in a Wcast-qual safe way. This also allows to remove the casts from the current users. Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

The latter have only been added "to allow multiple forks to add fields to the structure without breaking ABI" [1], but libav is no more, so this is not needed any longer.

This also enables exporting other stream items like thumbnails, which may be present in non tiled HEIF images too. For those, the primary stream will be tagged with the default disposition.

* avcodec/avcodec: Deprecate AV_INPUT_BUFFER_MIN_SIZEAndreas Rheinhardt2024-02-211-0/+3
| | | | | | | | | | | It used to be used with preallocated packet buffers with the old encode API, but said API is no more and therefore there is no reason for this to be public any more.

| | | | | | | | | | The existing (and upcoming) available group types are meant to combine several streams for presentation, with the result being treated as if it was a stream itself.

* avfilter: add negotiation API for color space/rangeNiklas Haas2023-12-311-0/+3
| | | | | | | | | | | | | | | | | | | Motivated by YUVJ removal. This change will allow full negotiation between color ranges and matrices as needed. By default, all ranges and matrices are marked as supported. Because grayscale formats are currently handled very inconsistently (and in particular, assumed as forced full-range by swscale), we exclude them from negotiation altogether for the time being, to get this API merged. After filter negotiation is available, we can relax the grayscale-is-forced-jpeg restriction again, when it will be more feasible to do so without breaking a million test cases. Note that this commit updates one FATE test as a consequence of the sanity fallback for non-YUV formats. In particular, the test case now writes rgb24(pc, gbr/unspecified/unspecified) to the matroska file, instead of rgb24(unspecified/unspecified/unspecified) as before.

I have no idea why this is not just a flag. Motivated by my desire to add yet another check for XYZ to the codebase, and I'd rather not keep copy/pasting a string comparison hack.

| | | | | | | | | | | | Deprecate AVStream.side_data and its helpers in favor of the AVStream's codecpar.coded_side_data. This will considerably simplify the propagation of global side data to decoders and from encoders. Instead of having to do it inside packets, it will be available during init(). Global and frame specific side data will therefore be distinct. Signed-off-by: James Almer <jamrial@gmail.com>

* avformat/avformat: Deprecate AVFMT_ALLOW_FLUSHAndreas Rheinhardt2023-10-031-0/+4
| | | | | | | | | | | | | | | It is of no value to the user, because every muxer can always be flushed with a NULL packet. As its documentation shows ("If not set, the muxer will not receive a NULL packet in the write_packet function") it is actually an internal flag that has been publically exposed because there was no internal flags field for output formats for a long time. But now there is and so use it by replacing the public flag with a private one.

| | | | | | | | | | | | | | | | | | | | | | | | ISO C++ forbids compound-literals. It's not available with MSVC. This is a known issue from 10 years ago, and that's why there is a av_get_time_base_q(). Since we have no plan to remove AV_TIME_BASE_Q, just make it available in C++. There are multiple choices: 1. Use C++11 syntax: AVRational{1, AV_TIME_BASE} Users may still use C++98 to write new code. So no. 2. Use av_get_time_base_q(). It's for this purpose. But it's not compile time constants as AV_TIME_BASE_Q in C. So I choose av_make_q() as Anton's suggestion. https://libav-devel.libav.narkive.com/ZQCWfTun/patch-0-2-fix-avutil-h-usage-from-c Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>

* avutil/imgutils: Add wrapper for av_image_copy() to avoid castsAndreas Rheinhardt2023-09-121-0/+4
| | | | | | | | | | | | av_image_copy() accepts const uint8_t* const * as source; lots of user have uint8_t* const * and therefore either cast (the majority) or copy the array of pointers. This commit changes this by adding a static inline wrapper for av_image_copy() that casts between the two types so that we do not need to add casts everywhere else.
