* configure: extend SDL check to accept all 2.x versionsChristopher Degawa2022-05-12
| | | | | | | | | | | sdl2 recently changed their versioning, moving the patch level to minor level https://github.com/libsdl-org/SDL/commit/cd7c2f1de7d9e418bb554047d714dd7cacc020ff and have said that they will instead ship sdl3.pc for 3.0.0 Fixes ticket 9768 Signed-off-by: Christopher Degawa <ccom@randomderp.com> Signed-off-by: Gyan Doshi <ffmpeg@gyani.pro>

* lavfi: add vf_iccdetect for parsing ICC profilesNiklas Haas2022-04-23
| | | | | | | | | | | | | | | This filter is designed to parse embedded ICC profiles and attempt extracting colorspace tags from them, updating the AVFrame metadata accordingly. This is intentionally made a separate filter, rather than being part of libavcodec itself, so that it's an opt-in behavior for the time being. This also gives the user more flexibility to e.g. first attach an ICC profile and then also set the colorspace tags from it. This makes #9673 possible, though not automatic.

* lavfi: add vf_iccgen for generating ICC profilesNiklas Haas2022-04-23
| | | | | | | | | This filter is designed to specifically cover the task of generating ICC profiles (and attaching them to output frames) on demand. Other tasks, such as ICC profile loading/stripping, or ICC profile application, are better left to separate filters (or included into e.g. vf_setparams). Signed-off-by: Niklas Haas <git@haasn.dev>
* lavfi: add ICC profile support via lcms2Niklas Haas2022-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces an optional dependency on lcms2 into FFmpeg. lcms2 is a widely used library for ICC profile handling, which apart from being used in almost all major image processing programs and video players, has also been deployed in browsers. As such, it's both widely available and well-tested. Add a few helpers to cover our major use cases. This commit merely introduces the helpers (and configure check), even though nothing uses them yet. It's worth pointing out that the reason the cmsToneCurves for each AVCOL_TRC are cached inside the context, is because constructing a cmsToneCurve requires evaluating the curve at 4096 (by default) grid points and constructing a LUT. So, we ideally only want to do this once per curve. This matters for e.g. ff_icc_profile_detect_transfer, which essentially compares a profile against all of these generated LUTs. Re-generating the LUTs for every iteration would be unnecessarily wasteful. The same consideration does not apply to e.g. cmsCreate*Profile, which is a very lightweight operation just involving struct allocation and setting a few pointers. The cutoff value of 0.01 was determined by experimentation. The lowest "false positive" delta I saw in practice was 0.13, and the largest "false negative" delta was 0.0008. So a value of 0.01 sits comfortaby almost exactly in the middle. Signed-off-by: Niklas Haas <git@haasn.dev>

* avformat: Add IPFS protocol support.Mark Gaiser2022-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for: - ffplay ipfs://<cid> - ffplay ipns://<cid> IPFS data can be played from so called "ipfs gateways". A gateway is essentially a webserver that gives access to the distributed IPFS network. This protocol support (ipfs and ipns) therefore translates ipfs:// and ipns:// to a http:// url. This resulting url is then handled by the http protocol. It could also be https depending on the gateway provided. To use this protocol, a gateway must be provided. If you do nothing it will try to find it in your $HOME/.ipfs/gateway file. The ways to set it manually are: 1. Define a -gateway <url> to the gateway. 2. Define $IPFS_GATEWAY with the full http link to the gateway. 3. Define $IPFS_PATH and point it to the IPFS data path. 4. Have IPFS running in your local user folder (under $HOME/.ipfs).

* avcodec/bsf: Add FFBitStreamFilter, hide internals of BSFsAndreas Rheinhardt2022-03-23
| | | | | | | | | | This patch is analogous to 20f972701806be20a77f808db332d9489343bb78: It hides the internal part of AVBitStreamFilter by adding a new internal structure FFBitStreamFilter (declared in bsf_internal.h) that has an AVBitStreamFilter as its first member; the internal part of AVBitStreamFilter is moved to this new structure.

* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

* avcodec/zlib_wrapper: Add wrapper for deflateInit()Andreas Rheinhardt2022-03-19
| | | | | | | | | | | The rationale is the same as for the wrappers for inflateInit(), although the case for it is admittedly not so strong because there are less users of deflateInit(). Also remove an unnecessary inclusion of config.h in libavformat/protocols.c in order to trigger a request for reconfigure (which is needed for CONFIG_DEFLATE_WRAPPER to take effect).

* avcodec/zlib_wrapper: Add wrappers for zlib inflateInit, inflateEndAndreas Rheinhardt2022-03-19
| | | | | | | | | | | | | | | | | It is not documented to be safe to call inflateEnd() on a z_stream that has never been successfully been initialized by inflateInit(), but just zeroed. It just happens to work and several codecs rely on this (they have FF_CODEC_CAP_INIT_CLEANUP set and even call inflateEnd() when inflateInit() failed or has never been called). To avoid this, other codecs recorded whether their zstream has been initialized successfully or not. This commit adds wrappers for inflateInit() and inflateEnd() that do what these other codecs do; furthermore, they also take care of properly setting up the zstream before inflateInit() and emit an error message in case of error.

* configure: move ranlib -D test after setting defaultsAdrian Ratiu2022-03-11
| | | | | | | | | | | | | | | | | In Gentoo and ChromeOS we want to allow pure LLVM builds without using GNU tools, so we block any unwanted mixed GNU/LLVM usages (GNU tools are still kept around in our chroots for projects like glibc which cannot yet be built otherwise). The default ${cross_prefix}${ranlib_default} points to GNU and fails, so move the test a bit later - after the defaults are set and the proper values get overriden - such that ffmpeg configure calls the llvm-ranlib we desire.

* configure: check avisynth header versionStephen Hutchinson2022-02-13
| | | | | | | | | | | | | | | The headers from version 3.7.1 are needed in order to support parsing of frame properties. avs/version.h has been generated as part of the AviSynth+ build process for a long time, but was never installed with the includes until version 3.7.1a. Checking for the presence of avs/version.h might have been sufficient, but a version check mechanism might be useful in the future. This does not change the version compatibility with the library itself; previous 3.x versions of AviSynth+ as well as AviSynth 2.6 can still be used with the demuxer.
