* avutil/pix{desc,fmt}: add new matrix coefficients from H.273 v3Jan Ekström2024-04-033-1/+7
| | | | | | | | | | | | * SMPTE ST 2128 IPT-C2 defines the coefficients utilized in DoVi Profile 5. Profile 5 can thus now be represented in VUI as {AVCOL_RANGE_JPEG, AVCOL_PRI_BT2020, AVCOL_TRC_SMPTE2084, AVCOL_SPC_IPT_C2, AVCHROMA_LOC_LEFT} (although other chroma sample locations are allowed). AVCOL_TRC_SMPTE2084 should in this case be interpreted as 'PQ with reshaping'. * YCgCo-Re and YCgCo-Ro define the bitexact YCgCo-R, where the number of bits added to a source RGB bit depth is 2 (i.e., even) and 1 (i.e., odd), respectively.

* avutil/hwcontext_vulkan: Include hwcontext.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | struct Foo * declares a new type (namely struct Foo) if there is no declaration of struct Foo already visible in the current scope; otherwise it is just a pointer to an element of the already declared type "struct Foo". There is a gotcha with the first case: struct Foo is only declared in its scope; a later declaration of struct Foo in an enclosing scope declares a different type. This happens in hwcontext_vulkan.h if it is included before hwcontext.h, because some declarations of struct AVHWDeviceContext and struct AVHWFramesContext have function prototype scope. Compilers warn about this (during checkheaders): ‘struct AVHWDeviceContext’ declared inside parameter list will not be visible outside of this definition or declaration Fix this by including hwcontext.h.

* all: Don't use ATOMIC_VAR_INITAndreas Rheinhardt2024-03-282-4/+4
| | | | | | | | | | | | | | | | | | | | C11 required to use ATOMIC_VAR_INIT to statically initialize atomic objects with static storage duration. Yet this macro was unsuitable for initializing structures [1] and was actually unneeded for all known implementations (this includes our compatibility fallback implementations which simply wrap the value in parentheses: #define ATOMIC_VAR_INIT(value) (value)). Therefore C17 deprecated the macro and C23 actually removed it [2]. Since commit 5ff0eb34d2b1089d3dd9f27fdb51520001709138 we default to C17 if the compiler supports it; Clang warns about ATOMIC_VAR_INIT in this mode. Given that no implementation ever needed this macro, this commit stops using it to avoid this warning.

* avutil/opt: Don't cast when the result might be misalignedAndreas Rheinhardt2024-03-281-14/+15
| | | | | | | | | | | | | | | | A pointer conversion is UB if the resulting pointer is not correctly aligned for the resultant type, even if no load/store is ever performed through that pointer (C11 6.3.2.3 (7)). This may happen in opt_copy_elem(), because the pointers are converted even when they belong to a type that does not guarantee sufficient alignment. Fix this by deferring the cast after having checked the type. Also make the casts -Wcast-qual safe and avoid an indirection for src. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avutil/opt: Avoid av_strdup(NULL)Andreas Rheinhardt2024-03-281-3/+7
| | | | | | | | | | | | | | | | | | It is not documented to be safe and in any case it is nonsense: Currently av_strdup(NULL) returns NULL and in order to distinguish this from a genuine allocation failure, opt_copy_elem() checked afterwards whether src was actually NULL. But then one can simply check in advance whether one should call av_strdup() at all. set_string() was even worse and returned ENOMEM in case the value to be duplicated is NULL; this only worked because av_opt_set_defaults2() does not check the return value at all (given that it can't propagate it). These two places account for 389114 of 390356 av_strdup(NULL) calls during one FATE run. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avutil/timestamp: change precision of av_ts_make_time_string()Marton Balint2024-03-251-3/+1

* avutil/timestamp: introduce av_ts_make_time_string2 for better precisionMarton Balint2024-03-254-1/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | av_ts_make_time_string() used "%.6g" format, but this format was losing precision even when the timestamp to be printed was not that large. For example for 3 hours (10800) seconds, only 1 decimal digit was printed, which made this format inaccurate when it was used in e.g. the silencedetect filter. Other detection filters printing timestamps had similar issues. Also time base parameter of the function was *AVRational instead of AVRational. Resolve these problems by introducing a new function, av_ts_make_time_string2(). We change the used format to "%.*f", use a precision of 6, except when printing values near 0, in which case we calculate the precision dynamically to aim for a similar precision in normal form as with %.6g. No longer using scientific representation can make parsing the timestamp easier for the users, we can safely do this because the theoretical maximum of INT64_MAX*INT32_MAX still fits into the string buffer in normal form. We somewhat imitate %g by trimming ending zeroes and the potential decimal point characters. In order not to trim "inf" as well, we assume that the decimal point string does not contain the letter "f". Note that depending on printf %f implementation, we might trim "infinity" to "inf".

* avutil/film_grain_params: add metadata to common structNiklas Haas2024-03-232-4/+56
| | | | | | | | | | | | 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.

* avutil/frame: Rename av_frame_side_data_get and add wrapper for itAndreas Rheinhardt2024-03-222-6/+21
| | | | | | | | | | | | | | | | | | | 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>
