* 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]>
* avcodec/cuviddec: use pre-existing chroma format informationTimo Rothenpieler2025-03-131-23/+8
| | | | Fixes #11505
* avcodec/Makefile: remove redundant objectTimo Rothenpieler2025-03-131-1/+0
| | | | | It's already listed in OBJS-$(CONFIG_JNI), which should cover all cases STLIBOBJS does and more.

* avcodec/sbcdec_data: Merge data into headerAndreas Rheinhardt2025-03-124-166/+126
| | | | | | | sbcdec_data.h is only included by sbcdec.c, so this won't cause the data to be included multiple times in the binary. Signed-off-by: Andreas Rheinhardt <[email protected]>
* all: Fix doxy comments wrongly designated as trailing ///<Andreas Rheinhardt2025-03-129-24/+21
| | | | | | | | | | | 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). Uninline all the others. Reviewed-by: Lynne <[email protected]> Signed-off-by: Andreas Rheinhardt <[email protected]>

* avcodec/put_bits: Add and use put_bits63()Andreas Rheinhardt2025-03-114-13/+28
| | | | | | | | | | | 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.

* lavc/vvc: Stricter bound on pps_exp_slice_height_in_ctus_minus1Frank Plowman2025-03-091-1/+1
| | | | | | | | | | When pps_num_exp_slices_in_tile[i] is nonzero, the ith tile is made up of pps_num_exp_slices_in_tile[i] slices stacked atop one another, where the height of the jth slice in the ith tile is given by pps_exp_slice_height_in_ctus_minus1[i][j]. The sum of the heights of the slices in the tile should not exceed the height of the tile itself. Signed-off-by: Frank Plowman <[email protected]>
* avcodec/snow: Remove outdated assertAndreas Rheinhardt2025-03-091-3/+0
| | | | | | | | | It comes from a time before frames were refcounted; it has indeed been added in a follow-up commit to c13e490dce1a66d79e1f053d8a38fb9b2eb53267: "codec_release_buffer: fix handling of non user buffers".

| | | | | | | | | | | This improves compression by 0.1% overall and 44% for the changed table I tried several other things but so far this is the best compromise between complexity and compression This can also be extended to 32 and 64bit floats Sponsored-by: Sovereign Tech Fund Signed-off-by: Michael Niedermayer <[email protected]>

* 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.
