* all: fix typos found by codespellTimo Rothenpieler4 days1-4/+4
|
* lavu/opt: deprecate av_opt_ptr()Anton Khirnov2024-10-161-0/+5
| | | | | | It has no more internal callers, and we do not want to support direct pointer access via AVOptions, as that constrains AVOption API extensions.
* lavu: deprecate av_opt_set_int_list() and related infrastructureAnton Khirnov2024-09-301-0/+2
| | | | It has no more users and is replaced by array-type options.
* lavu/opt: add API for setting array-type option valuesAnton Khirnov2024-09-061-0/+56
| | | | | | Previously one could only replace the entire array with a new one deserialized from a string. The new API allows inserting, replacing, and removing arbitrary element ranges.
* lavu/opt: add API for retrieving array-type option valuesAnton Khirnov2024-08-271-0/+40
| | | | | Previously one could only convert the entire array to a string, not access individual elements.
* lavu/opt: document underlying C types for enum AVOptionTypeAnton Khirnov2024-08-271-3/+75
|
* avutil/opt: add a note about the av_opt_{get,set}_chlayout() behaviorJames Almer2024-05-071-0/+8
| | | | | | Based on the one for av_opt_set_dict_val(). Signed-off-by: James Almer <jamrial@gmail.com>

* lavu/opt: add array optionsAnton Khirnov2024-03-081-2/+54
|
* lavu/opt: distinguish between native and foreign access for AVOption fieldsAnton Khirnov2024-03-081-0/+14
| | | | | | | | Native access is from the code that declared the options, foreign access is from code that is using the options. Forbid foreign access to AVOption.offset/default_val, for which there is no good reason, and which should allow us more freedom in extending their semantics in a compatible way.
* avutil/opt: Don't use AV_OPT_TYPE_FLAGS for sentinelsAndreas Rheinhardt2024-03-071-1/+1
| | | | | | Make AVOptionType start with 1 instead. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

|
* lavu/opt: cosmetics, move AV_OPT_FLAG_* out of AVOptionAnton Khirnov2024-03-011-35/+34
| | | | Also drop an obsolete FIXME.
* lavu/opt: cosmetics, change option flags to (1 << N) styleAnton Khirnov2024-03-011-12/+36
| | | | | It is easier to read. Also, change their doxy comments to use the same style.
* Revert "all: Don't set AVClass.item_name to its default value"Anton Khirnov2024-01-201-0/+2
| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.
* all: Don't set AVClass.item_name to its default valueAndreas Rheinhardt2023-12-221-2/+0
| | | | | | | | Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9; also avoids relocations. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avutil/opt: Document actual behaviour of av_opt_copy a bit moreAndreas Rheinhardt2021-08-171-0/+7
| | | | | | | | | In particular, document that av_opt_copy() always disentangles allocated options even on error; this guarantee is needed to e.g. properly free duplicated thread contexts in libavcodec on error.

* Remove obsolete version.h inclusionsAndreas Rheinhardt2021-07-221-1/+0
| | | | | | | These have mostly been added because of FF_API_*; yet when these were removed, removing the header has been forgotten. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavu/opt: add a more general child class iteration APIAnton Khirnov2020-06-101-8/+23
| | | | | | | Use opaque iteration state instead of the previous child class. This mirrors similar changes done in lavf/lavc. Deprecate the av_opt_child_class_next() API.
* avutil/opt: add AV_OPT_FLAG_CHILD_CONSTSMarton Balint2020-05-221-0/+1
| | | | | | | | This will be used for AVCodecContext->profile. By specifying constants in the encoders we won't have to use the common AVCodecContext options table and different encoders can use the same profile name even with different values. Signed-off-by: Marton Balint <cus@passwd.hu>
* avutil/opt: add full support for AV_OPT_TYPE_DICTMarton Balint2019-12-271-3/+7
