* avcodec/d3d12va_encode: texture array support for HEVCAraz Iusubov2025-09-031-0/+8
| | | | | | | | | This patch adds support for the texture array feature used by AMD boards in the D3D12 HEVC encoder. In texture array mode, a single texture array is shared for all reference and reconstructed pictures using different subresources. The implementation ensures compatibility and has been successfully tested on AMD, Intel, and NVIDIA GPUs.

* avcodec/avcodec: add AVCodecContext.alpha_modeNiklas Haas2025-09-021-0/+4
| | | | | | | | | | Following in the footsteps of the previous commit, this commit adds the new fields to AVCodecContext so we can start properly setting it on codecs, as well as limiting the list of supported options to detect a format mismatch during encode. This commit also sets up the necessary infrastructure to start using the newly added field in all codecs.
* avfilter: add link negotiation for AVAlphaModeNiklas Haas2025-09-021-0/+3
|
* avutil/frame: add AVFrame.alpha_modeNiklas Haas2025-09-021-0/+4
| | | | | | | FFmpeg currently handles alpha in a quasi-arbitrary way. Some filters/codecs assume alpha is premultiplied, others assume it is independent. If there is to be any hope for order in this chaos, we need to start by defining an enum for the possible range of values.
* swscale: add SWS_UNSTABLE flagNiklas Haas2025-09-011-0/+3
| | | | | | Give users and developers a way to opt in to the new format conversion code, and more code from the swscale rewrite in general, even while development is still ongoing.

* avcodec/exif: make the get and remove helpers take a flags argument as inputJames Almer2025-08-241-0/+3
| | | | | | | | | | | | This makes the functions extensible, as future behavior change flags can be introduced. This is strictly speaking not an API break. Only if a user was setting recursive to anything other than 1 it would now behave differently, but given these functions have been in the tree for only a few days, the chances for that are practically zero.

* avcodec/exif: don't expose a private function in an installed headerJames Almer2025-08-201-2/+0
| | | | | | And it doesn't need an entry in APIChanges, given it's not public API. Signed-off-by: James Almer <[email protected]>

* lavf: mxf [de]muxer now uses AV_CODEC_ID_SMPTE_436M_ANC instead of ..._NONEJacob Lifshay2025-08-081-0/+4

* lavc: add AV_CODEC_ID_SMPTE_436M_ANCJacob Lifshay2025-08-081-0/+3
| | | | | | | | | | This creates a new codec id for mxf vbi_vanc_smpte_436M streams. This makes it easier to use from other [de]muxers and bitstream filters.

* 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 <[email protected]>

* avcodec: deprecate AVCodecContext propertiesMarton Balint2025-01-051-0/+3

* 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.
