* avutil/tests/dict: Explicitly test av_dict_iterate()Andreas Rheinhardt2022-12-071-5/+25
| | | | | | | | This commit tests it in a way that automatically checks that using av_dict_iterate() is equivalent to using av_dict_get() with key "" and AV_DICT_IGNORE_SUFFIX. Signed-off-by: Andreas Rheinhardt <[email protected]>

* avcodec/nvenc: explicitly disable lookahead if lacking sufficient surfacesTimo Rothenpieler2022-12-051-0/+1
| | | | | It could already be enabled by the preset, so it needs explicitly disabled in this case.

* avcodec/wavpack: Fix overflow in p=31Michael Niedermayer2022-12-041-1/+1
| | | | | | | | | | | Untested with "non fuzzed" samples as i have no such file The reference 5.6.0 decoder appears to also have undefined behavior in the lossless codepath for this Fixes: shift exponent 32 is too large for 32-bit type 'int' Fixes: 50930/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_WAVPACK_fuzzer-6319201949712384 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <[email protected]>
* avfilter/vf_libplacebo: ensure filter hwdevice is a vulkan oneTimo Rothenpieler2022-12-041-1/+10
| | | | | Before this, the filter blindly casts to AVVulkanDeviceContext and passes invalid values to libplacebo if it's not.
* avfilter/vf_exposure: ensure that scale is always > 0Paul B Mahol2022-12-041-1/+3

* avfilter/avf_showcwt: write also to alpha plane if availablePaul B Mahol2022-12-041-11/+31

|
* lavu/tx: zero-out imaginary of last coefficient in forward RDFTsLynne2022-12-031-1/+1
| | | | | We didn't do this, because it's zero anyway, but it prevents users from using uninitialized memory in calculations.
* avcodec/cfhdenc: stop crashing on heights not multiple of 8Paul B Mahol2022-12-031-10/+13
| | | | Fixes overreads and artifacts for some heights not multiple of 16.
* fate: add QOI/XBM/XWD image2pipe testsPaul B Mahol2022-12-034-0/+12

* avcodec/ass: specify a permissive encodingOneric2022-12-0325-25/+25
| | | | | | | | | | | | | | | The Encoding field (and the \fe tag) allows to limit font selection to only those fonts declaring support for the specified codepage in their OS/2's table "Code Page Character Range" field. Particularly, Encoding=0 means only font's declaring support for "ANSI", or rather "Latin (Western European)", are allowed to be selected. Specifying Encoding=1 allows all fonts to be considered. We do not want to limit font selection, so specify Encoding=1. NB: at the time of writing libass only partially supports this field, thus hiding the issue in any libass-based renderer. A VSFilter-based DirectShow filter or XySubFilter will reveal the issue when a font not declaring support for latin characters is specified in a style.
* avcodec/ass: accurately preserve coloursOneric2022-12-0325-0/+25
| | | | | | | | | | | | | | | | | | Colour values used in ASS files without a "YCbCr Matrix" header set to "None" are subject to colour mangling, due to how ASS was historically conceived. A more in-depth description can be found in the documetation inside libass' public ass_types.h header. The important part is, if this header is not set to "None", the final output colours can deviate from the literal value specified in the file. When converting from non-ASS formats we do not want any colour shift to happen, so let's set the appropiate header. NB: ffmpeg's subtitle filter, does not follow libass' documentation regarding colour mangling, thus hiding the bug. Anything based on VSFilter, XySubFilter or e.g. mpv do and might show the issue. (Of course native ASS subs, which _do_ rely on colour mangling won't work properly with the subtitle filter, but this can be fixed another time)
* avcodec/ass: fix commentOneric2022-12-031-1/+1
| | | | | | | | | There is no v4 ASS. There are versions 1 to 4 of SSA (with only v4 being supported by softsub renderers), ASS which declares itself as v4+ or v4.00+, and the rarely used v4++/v4.00++, which isn't fully supported by libass. As reflected by the [V4+ Styles] section header, FFmpeg uses ASS, not SSA v4, so adjust the comment accordingly.
