* avcodec/decode: Move is_open check to avcodec_receive_frame()Andreas Rheinhardt2025-03-132-3/+3
| | | | | | | It also applies to scenarios where ff_encode_receive_frame() is used. Also remove the redundant av_codec_is_decoder(). Signed-off-by: Andreas Rheinhardt <[email protected]>

| | | | | | | | | | | The ///< or /**< form of doxygen comments are only to be used when the documentation follows the member and the comment block starts on the same line as the member. This commit fixes wrong uses of them; in particular, this fixes the comment for mb_height in H.264 SPS's structure which was wrongly added to mb_width.

* avcodec/vc2enc: Avoid excessive inliningAndreas Rheinhardt2025-03-121-2/+7
| | | | | | | | | | There is no reason to inline put_vc2_ue_uint() everywhere; only one call site is actually hot: The one in encode_subband() (which accounts for 35735040 of 35739495 calls to said function in a FATE run).

* libavfilter: guard against ff_draw_init/ff_draw_init2 failuresNil Fons Miret2025-03-1112-26/+109
| | | | | | | | | | | The return value of ff_draw_init and ff_draw_init2 are not checked in most usages. However, if they return an error, they don't get to the point where they set the attributes of the FFDrawContext. These functions are typically used in conjunction with ff_draw_color, which checks draw->desc->flags, causing a null pointer dereference.

* hwcontext_vulkan: add support for mapping multiplane images into CUDALynne2025-03-111-102/+160
| | | | | | | | | | | | | This patch refactors the CUDA import code to allow for Vulkan images with multiple planes to be mapped. Currently, a driver bug exists which causes NV12 images to be mapped incorrectly when the memory being mapped contains both planes, the issue has been reported to NVIDIA. yuv420p does work correctly, however. This is still an improvement, as the code used to crash when trying to map the memory, unless disable_multiplane=1 was given as an option.

* avcodec/put_bits: Add and use put_bits63()Andreas Rheinhardt2025-03-116-15/+30
| | | | | | | | | | | When using a 64bit PutBitContext (i.e. on x64), put_bits_no_assert() can naturally write up to 63 bits. So one can avoid treating the cases <32bits, 32 bits and <63 bits differently. As it turns out, no user actually wants to write 64 bit at once (maybe except testprograms).

* avcodec/vc2enc: Simplify writing dirac golomb codesAndreas Rheinhardt2025-03-111-27/+3
| | | | | | | | | | The earlier code used a loop to determine the number of bits used and called ff_log2() on a power of two (and it would be easy to keep track of the exponent of said power-of-two); neither GCC nor Clang optimized the loop away or avoided the ff_log2(). This patch replaces the loop and the log2 with a single av_log2(). Signed-off-by: Andreas Rheinhardt <[email protected]>

* avcodec/codec_internal, all: Use macros to set deprecated AVCodec fieldsAndreas Rheinhardt2025-03-10213-834/+451
| | | | | | | | | | | | | | The aim of this is twofold: a) Clang warns when setting a deprecated field in a definition and because several of the widely set AVCodec fields are deprecated, one gets several hundred warnings from Clang for an ordinary build. Yet fortunately Clang (unlike GCC) allows to disable deprecation warnings inside a definition, so that one can create simple macros to set these fields that also suppress deprecation warnings for Clang. This has already been done in fdff1b9cbfd8cf5a9810c29efa4baf13a4786742 for AVCodec.channel_layouts. b) Using macros will allow to easily migrate these fields to internal ones.

* avcodec/ffv1: flip half of float16 and Compactify floatsMichael Niedermayer2025-03-083-0/+71
| | | | | | | | | | | | | | | | | | | | | | | float16 (and more so float32) have many odd values half the values are negative, many are larger than "1.0" and many values are very close to 0. Storing the 16bits as is, looses compression because of the mixture of dense and sparse regions and also many completely unused ones. This simply remaps the 65536 values so no unused values remain This improves compression by about 1.5% for the ACES_OT_VWG_SampleFrames testset (this testset contains all kind of funny values including many images with negative rgb values) The space needed for the map is insignificant compared to the compression gained This patch also flips half the float range as it can be done using the same table.
