* configure: Allow mixing declarations and statementsAndreas Rheinhardt2025-04-092-8/+0
| | | | | | | | | | | | | This C90 rule forces us to use a too big scope and should therefore be dropped. Given that we already require C11, all supported compilers can handle mixed declarations and statements just fine.

* avutil/tests/channel_layout: Improve enum range checkAndreas Rheinhardt2025-04-091-1/+1
| | | | | | | | | | Both GCC and Clang use unsigned as underlying type of an enum with no negative enumeration constants, making checks like "layout->order >= 0" here tautologically true. Clang warns about this. Combine both range checks by casting to unsigned to suppress this warning. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavf/id3v2dec: support multiple values and TIPL framesrcombs2025-04-071-21/+28
| | | | | | | | | | | | | Fixes https://trac.ffmpeg.org/ticket/6949 Ordinary text frames in ID3v2 are allowed to have multiple (null-separated) values. This technically isn't allowed in TXXX, but it's used in practice by Picard, and supporting it is harmless. TIPL/IPL (Involved People List) and TMCL (Musician Credits List) work similarly to TXXX, but alternate key-value-key-value. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avutil/tests/aes_ctr: also check the encrypted bufferJames Almer2025-04-051-0/+23
| | | | | | | | | | | | | | The test in its current form is just ensuring the plain text output is the same as the plain text input, not bothering to check if anything was done with the latter. av_aes_ctr_crypt() could be a simple memcpy under the hood and this test would still succeed. To check the integrity of the encrypted buffer, both the IV and the key need to be fixed. As such, and in order to not remove the existing randomization of the input IV, do two runs, one with random initialization data, and one with static data.

* avcodec/d3d12va_decode: enable reference-only modeAraz Iusubov2025-04-052-12/+165
| | | | | | | | | | | | | The Reference-Only feature in DirectX 12 is a memory optimization technique designed for video decoding scenarios. This feature requires that reference resources must be allocated with the D3D12_RESOURCE_FLAG_VIDEO_DECODE_REFERENCE_ONLY resource flag. Reference textures must also be separated from output textures. This feature is not supported in the current version of ffmpeg. Since AMD GPU uses this feature in Direct 12 decoder, ffmpeg does not support AMD GPU Direct 12 decoding. Signed-off-by: Tong Wu <wutong1208@outlook.com>

| | | | | | | | | | | | That is instead of a fixed 65536, we now allocate only as many as there are pixels. We also allocate only for the encoder and only when remapping is enabled and only for 32bit per sample This should reduce memory consumption, the 2nd array will be dealt with in a future commit Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avcodec/decode: Fix avcodec parameters when bsfs are enable by decoderZhao Zhili2025-04-051-0/+3
| | | | | | BSF can update extradata, e.g., vvc_mp4toannexb. If we don't copy bsf->par_out back to avcodec context, decoder can get extradata in mp4 format, while packets are in annexb format.

* configure: Check for AVCaptureSession as dependency to avfoundationMartin Storsjö2025-04-041-2/+13
| | | | | | | | | This class is unavailable on tvOS before 17.0 (and macOS before 10.7 and iOS before 4.0, but those are fairly ancient). This makes sure that we don't try to build the avfoundation indevice for such OSes. Signed-off-by: Martin Storsjö <martin@martin.st>
* avfoundation: Fix compilation for OSes other than macOS and iOSMartin Storsjö2025-04-041-1/+3
| | | | | | | | | | | | | | E.g. tvOS doesn't have devicesWithMediaType. In principle, we could probably disable building the whole input device on such OSes, but that would either require testing explicitly for the OS type in configure (which we don't do anywhere so far), or test for individual objective C methods. This approach allows the code to compile, but no input devices will be found at runtime. Signed-off-by: Martin Storsjö <martin@martin.st>
* avfilter/vf_libplacebo: don't explode on zero FPS informationNiklas Haas2025-04-031-1/+1
| | | | | | | | While technically not specifiad as valid by the AVFilterLink documentation, it is currently possible to get an FPS of zero from various sources inside libavfilter (notably vf_buffersrc). Avoid a division by zero and resulting infinity when this happens.
* avformat: Fix AV1 RTP wrong log conditionChris Hodges2025-04-031-1/+1

* avutil/Makefile: Only include half2float, float2half when neededAndreas Rheinhardt2025-04-031-2/+7
| | | | | | | | They are not needed for shared builds (and because --gc-sections is not the default for shared builds, they were included by default included in libavutil since bf22c4cc3e005c01f50e233b1582fd1d8051aed9). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vdpau: Only include mpegvideodec.h when usedAndreas Rheinhardt2025-04-031-1/+2
| | | | | | | | | | | | | mpegvideodec.h includes mpegvideodata.h which in turn contains a "static const uint8_t *const ff_mpeg1_dc_scale_table = ff_mpeg12_dc_scale_table[0]"; yet if mpegvideo is disabled, ff_mpeg12_dc_scale_table is not available, yet a non-optimizing compiler (like GCC with -O0) may emit ff_mpeg1_dc_scale_table and therefore a reference to ff_mpeg12_dc_scale_table nevertheless. Fix this by only including mpegvideodec.h if it is needed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

(ff_h2656_put_{uni_,}4tap_hv32_8_avx2 are now only called from exactly one callsite (in ff_hevc_put_{uni_,}epel_hv32_8_avx2) and could be inlined.)
