* avutil/avassert: Add av_unreachable() and av_assume() macrosAndreas Rheinhardt2025-05-211-0/+3
| | | | | | | | | | | | | Useful to let the compiler and static analyzers know that something is unreachable without adding an av_assert (which would be either dead for the compiler or add runtime overhead) for this. The implementation used here enforces the use of a message to provide a reason why a particular code is supposed to be unreachable.

| | | | | | This commit adds a 32-bit *integer* planar RGBA format. Vulkan FFv1 decoding is best performed on separate planes, rather than packed RGBA (i.e. RGBA128), hence this is useful as an intermediate format.

* avcodec: add AV_CODEC_ID_IVTV_VBIScott Theisen2025-02-091-0/+3
| | | | | | | | | | | | | | | | | IVTV, a Linux driver for TV tuners, and V4L2 utilize a coding named after IVTV to carry sliced VBI data in MPEG streams produced by tuner cards with VBI capture capability and an MPEG-2 encoder SoC. IVTV or V4L2 driver will transport the coded data into a MPEG-PS private stream ("IVTV") that can be captured from the card alongside the video/audio. The data could include: EIA-608, Teletext, WSS (PAL widescreen signaling), or VPS (PAL VCR signaling). Signed-off-by: Marth64 <marth64@proxyid.net>

* avcodec/libjxl: add animated JPEG XL encoderLeo Izen2025-01-031-0/+3
| | | | | | | | | | | | | libjxl supports animated encoding, so we add a wrapper to the library using the receive_packet callback method. This code was based largely on a patch sent by Zsolt Vadász, although it was updated to use more recent coding practices and many of the leaks and issues were fixed.

* avutil/frame: add av_frame_side_data_remove_by_props()Niklas Haas2024-12-231-0/+3
| | | | | | | | | | As discussed in the previous commit, we often need a convenient way of stripping all side data related to a certain aspect of the frame. This helper accomplishes just that. I considered also adding a way to match only side data matching *all* properties, but I think this is sufficiently useless in practise to not warrant inclusion in the API.
* avutil/frame: add AV_SIDE_DATA_PROP_{SIZE,COLOR}_DEPENDENTNiklas Haas2024-12-231-0/+3
| | | | | | | | | | | | | | | | | | Many filters modify certain aspects of frame data, e.g. through resizing (vf_*scale* family), color volume mapping (vf_lut*, vf_tonemap*), or possibly others. When this happens, we should strip all frame side data that will no longer be correct/relevant after the operation. For example, changing the image size should invalidate AV_FRAME_DATA_PANSCAN because the crop window (given in pixels) no longer corresponds to the actual image size. For another example, tone-mapping filters (e.g. from HDR to SDR) should strip all of the dynamic HDR related metadata. Since there are a lot of different side data types that are affected by such operations, it makes sense to establish this information in a common, easily accessible way. The existing side data properties enum is a perfect fit for this.
* swscale: add ICC intent enum and optionNiklas Haas2024-12-231-0/+3
| | | | | | | | This setting can be used to infuence the type of tone and gamut mapping used internally when color space conversions are required. As discussed at VDD'24, the default was set to relative colorimetric clipping, which is approximately associative, surjective and idempotent. As such, it roundtrips well, although it is strictly speaking not associative on out-of-gamut colors.
* lavc/packet: add API for an AVPacket-based AVContainerFifoAnton Khirnov2024-12-151-0/+3
|
* lavc/container_fifo: move to lavu and make publicAnton Khirnov2024-12-151-1/+4
| | | | | | | | | | | | | | This can be useful in other places, e.g. it can replace objpool in fftools. The API is modified in the following nontrivial ways: * opaque pointers can be passed through to all user callbacks * read and write were previously separate callbacks in order to accomodate the caller wishing to write a new reference to the FIFO and keep the original one; the two callbacks are now merged into one, and a flags argument is added that allows to request such behaviour on a per-call basis * new peek and drain functions
* lavc/refstruct: move to lavu and make publicAnton Khirnov2024-12-151-0/+4
| | | | It is highly versatile and generally useful.

* avutil/csp: add EOTF function definitionsNiklas Haas2024-12-051-0/+3
| | | | | | | | | | | | The existing av_csp_trc_func_from_id() mostly implements the OETF, except for PQ. As such, we are currently missing a precise definition of an ITU-R EOTF. Introduce the new functions av_csp_itu_eotf() and av_csp_itu_eotf_inv(), to fill this void. Note that this is not possible in all cases, e.g. AVCOL_TRC_LOG which has no corresponding EOTF definition in any ITU-R standard. Note that we cannot implement the proper HLG and SMPTE 428 OOTFs without access to all three color channels, because they are not independent per channel. As a result, we need to define them on double[3] instead of double (*func)(double).
* avutil/csp: add av_csp_trc_inv_from_id()Niklas Haas2024-12-051-0/+3
| | | | | Mathematical inverse of av_csp_trc_from_id(), plus testing to make sure it roundtrips correctly with the corresponding TRC.
* swscale: introduce new, dynamic scaling APINiklas Haas2024-11-251-0/+4
| | | | | | | | | | | | | | | | | | | | | | | 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: organize and better document flagsNiklas Haas2024-11-251-0/+3
| | | | | | | | | | | | 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: expose SwsContext publiclyNiklas Haas2024-11-251-0/+3
| | | | | | | | | | 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>
* avutil/frame: also align data pointers in av_frame_get_buffer()Pavel Koshevoy2024-11-221-0/+4
| | | | | | | | | | | | | | | This avoids unpleasant surprises to av_frame_get_buffer callers that explicitly specified 64-byte alignment and didn't get AVFrame.data pointers that are 64-byte aligned. For example, see https://github.com/sekrit-twc/zimg/issues/212 Although the zscale issue has already been resolved by other means it would still be prudent to improve the behavior of av_frame_get_buffer to fix any unknown and future instances of similar issues.
