* avcodec: deprecate sonicJ. Dekker2024-11-252-0/+7
| | | | | | | | | | | | | This is an experimental and research codec of which ffmpeg is the only encoder and decoder, development has stalled since 2013 and these files don't exist in the wild. Deprecate the encoders to be removed next major bump, decoders to be removed one bump afterwards. We also disable the the encoders by default in configure, the decoders should be disabled by default next bump. Signed-off-by: J.

* doc: add styles for good/bad code examplesMarvin Scholz2024-11-251-1/+1
| | | | | | Makes it easier to immediately see if the code examples given in the style documentation are good or bad examples, making it harder to accidentally confuse a bad example for a good one.
* doc/developer: add examples to clarify code styleMarvin Scholz2024-11-251-1/+100
| | | | | | Given the frequency that new developers, myself included, get the code style wrong, it is useful to add some examples to clarify how things should be done.
* MAINTAINERS: Add myself as Darwin maintainerMarvin Scholz2024-11-251-0/+1
| | | | | | | | | | I do some development and usage of FFmpeg regularly on macOS and sent some patches to fix issues specific to Darwin in the past so I think it makes sense to add myself as maintainer so people know they can ping me if required, for Darwin specific issues/testing. I have both Intel and Apple Silicon (aarch64) machines as well as older Macs for testing on older macOS versions if necessary.

* avfilter/vf_scale: fix off-by-one in loop boundsNiklas Haas2024-11-251-2/+2
| | | | | | | | Results in over-read of the array. Fortunately, the excess element was never actually used, but it still triggers ASAN (and could in theory trigger a segfault). Fixes: 04ce01df0bb2d66e143bcfcea439afc2a1b8d96e
* MAINTAINERS: list csp.c and csp.h maintainersLeo Izen2024-11-251-0/+1
| | | | | | | | | Ronald S. Bultje wrote most of the code before there was a refactor and condense (which I mostly wrote). As such, listing both him and myself as maintainers of csp.h and csp.h, which previously had no maintainer listed at all (after conferring on IRC). Signed-off-by: Leo Izen <leo.izen@gmail.com>
* avfilter/vf_scale: switch to new swscale APINiklas Haas2024-11-251-274/+77
| | | | | | | | | Most logic from this filter has been co-opted into swscale itself, allowing the resulting filter to be substantially simpler as it no longer has to worry about context initialization, interlacing, etc. Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>
* tests/swscale: add a benchmarking modeNiklas Haas2024-11-251-25/+68
| | | | | | | | With the ability to set the thread count as well. This benchmark includes the constant overhead of context initialization. Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>
* tests/swscale: rewrite on top of new APINiklas Haas2024-11-251-381/+284
| | | | | | | | | | | | | This rewrite cleans up the code to use AVFrames and the new swscale API. The log format has also been simplified and expanded to account for the new options. (Not yet implemented) The self testing code path has also been expanded to test the new swscale implementation against the old one, to serve as an unchanging reference. This does not accomplish much yet, but serves as a framework for future work. Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>
* swscale: introduce new, dynamic scaling APINiklas Haas2024-11-257-30/+276
| | | | | | | | | | | | | | | | | | | | | | | As part of a larger, ongoing effort to modernize and partially rewrite libswscale, it was decided and generally agreed upon to introduce a new public API for libswscale. This API is designed to be less stateful, more explicitly defined, and considerably easier to use than the existing one. Most of the API work has been already accomplished in the previous commits, this commit merely introduces the ability to use sws_scale_frame() dynamically, without prior sws_init_context() calls. Instead, the new API takes frame properties from the frames themselves, and the implementation is based on the new SwsGraph API, which we simply reinitialize as needed. This high-level wrapper also recreates the logic that used to live inside vf_scale for scaling interlaced frames, enabling it to be reused more easily by end users. Finally, this function is designed to simply copy refs directly when nothing needs to be done, substantially improving throughput of the noop fast path.

* swscale/graph: add new high-level scaler dispatch mechanismNiklas Haas2024-11-253-0/+770
| | | | | | | | | | | | | | | | | | | | | | | This interface has been designed from the ground up to serve as a new framework for dispatching various scaling operations at a high level. This will eventually replace the old ad-hoc system of using cascaded contexts, as well as allowing us to plug in more dynamic scaling passes requiring intermediate steps, such as colorspace conversions, etc. The starter implementation merely piggybacks off the existing sws_init() and sws_scale(), functions, though it does bring the immediate improvement of splitting up cascaded functions and pre/post conversion functions into separate filter passes, which allows them to e.g. be executed in parallel even when the main scaler is required to be single threaded. Additionally, a dedicated (multi-threaded) noop memcpy pass substantially improves throughput of that fast path. Follow-up commits will eventually expand this to move all of the scaling decision logic into the graph init function, and also eliminate some of the current special cases.

* swscale/internal: expose sws_init_single_context() internallyNiklas Haas2024-11-252-4/+7

* swscale: organize and better document flagsNiklas Haas2024-11-253-51/+70
| | | | | | | | | | | | Group them into an enum rather than random #defines, and document their behavior a bit more obviously. Of particular note, I discovered that SWS_DIRECT_BGR is not referenced anywhere else in the code base. As such, I have moved it to the deprecated section, alongside SWS_ERROR_DIFFUSION.

* swscale: eliminate redundant SwsInternal accessesNiklas Haas2024-11-257-208/+203
| | | | | | | | This is a purely cosmetic commit aimed at replacing accesses to SwsInternal.opts by direct access to SwsContext wherever convenient. Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>
* swscale: expose SwsContext publiclyNiklas Haas2024-11-255-119/+149
| | | | | | | | | | Following in the footsteps of the work in the previous commit, it's now relatively straightforward to expose the options struct publicly as SwsContext. This is a step towards making this more user friendly, as well as following API conventions established elsewhere. Sponsored-by: Sovereign Tech Fund Signed-off-by: Niklas Haas <git@haasn.dev>

* avcodec/codec_desc: remove Intra Only prop for AACJames Almer2024-11-242-3/+3
| | | | | | | | | | | xHE-AAC is a profile where some frames depend on other key frames, named IPF. By setting the codec as Intra Only, all frames output by decoders and all packets output by encoders/demuxers will be unconditionally flaged as keyframes, which is incorrect.
