* avcodec/mfenc: add support for D3D11 input surfacesDash Santosh3 days2-29/+185
| | | | | | | | Adds D3D11 input surface support to the MediaFoundation encoder (mfenc), allowing direct encoding of GPU frames without readback to system memory. This improves performance and compatibility when used alongside scale_d3d11. Signed-off-by: Dash Santosh <dash.sathyanarayanan@multicorewareinc.com>
* avfilter: add scale_d3d11 filterDash Santosh3 days6-0/+472
| | | | | | | This commit introduces a new hardware-accelerated video filter, scale_d3d11, which performs scaling and format conversion using Direct3D 11. The filter enables efficient GPU-based scaling and pixel format conversion (p010 to nv12), reducing CPU overhead and latency in video pipelines.

* avfilter/avfiltergraph: add logging for filter formatsNiklas Haas4 days1-1/+63
| | | | | | | | | | | | | | There is no convenient way, from the command line, to figure out which formats a filter actually supports. This commit changes that by adding a log output, at debug level, to simply print the list of formats each filter advertises on its links, before any negotiation. Furthermore, we can use the exact same helper function to also print out the corresponding filter links when there is an error during format negotiation. We need to use AV_BRINT_SIZE_UNLIMITED because the default format list for filters like vf_scale is about 1700 characters long, significantly larger than the the 1 kB default buffer.

* swscale/alphablend: don't overread alpha plane on subsampled odd sizeNiklas Haas4 days1-13/+19
| | | | | | | | | | | | | This function overreads the input plane for odd dimensions, because the chroma plane is always rounded up, which means (xy << subsample) + 1 exceeds the actual alpha plane size.

* Revert "avformat/tls_openssl: properly get new BIO index"Kacper Michajłow5 days1-14/+4
| | | | | | | | | | | | | | | | | | | | | | | BIO_get_new_index() is static counter meant to get index for custom bio type definition. As we can read in the documentation: > Note that BIO_get_new_index() can only be used 127 times before it > returns an error. We cannot call it repeatedly, because it will fail eventually. To my understanding the index is not needed in our use and we could safely use BIO_TYPE_NONE. Documentation states: > type can be set to either BIO_TYPE_NONE or via BIO_get_new_index() if > a unique type is required for searching (See BIO_find_type(3)) We don't use any search related functions.

* lavc/vvc: Add max parameter to kth_order_egk_decodeFrank Plowman6 days3-19/+25
| | | | | | | | | | | | | | | Prior to this patch, kth_order_egk_decode could read arbitrarily large values which then overflowed and caused various issues. Patch fixes this by making kth_order_egk_decode falliable, requiring the caller to specify an upper bound and returning an error if the read value would exceed that bound. This patch resolves the same issue as eb52251c0ab025b6b40b28994bc9dc616813b190, but I think this is the proper fix as it also addresses issues with syntax elements besides ff_vvc_num_signalled_palette_entries.

* avformat/hlsenc: limit segments count to search duplicated segments filenamesArtem Smorodin7 days1-1/+1
| | | | | | | | | This linear search has a complexity of O(n). When ffmpeg attempts to parse a playlist containing approximately 100,000 segments, it effectively causes a hang for several minutes. This patch limits the allowed size for duplicate searches to a reasonable value. Now it takes between 0.5 and a few seconds (tested on different devices) instead of several minutes.

* avformat/movenc: fix HEVC fmp4 HLS init segment for Apple playbackDavid McElroy7 days1-1/+1
| | | | | | | | | | | | | | | | | | | | | | HEVC fmp4 HLS video produced by ffmpeg is currently unplayable on Apple software (Safari, QuickTime, AVFoundation). This is caused by an empty sdtp atom being erroneously written to the fmp4 init segment. The `has_disposable` flag can be set for a track with B-frames, but the init segment contains no actual frames (track->entry == 0). Writing an sdtp atom in this case is incorrect and causes Apple's parsers to reject the file. This patch fixes the issue by ensuring the sdtp atom is only written if track->entry is non-zero. A similar patch was proposed in November 2023 by Jay Zhang, but it was never merged.

* avfilter/vf_libplacebo: composite multiple inputs in linear lightNiklas Haas7 days1-0/+51
| | | | | | | | | | | This gives vastly improved blending results than when blending directly in the desired output colorspace. Overridable by the existing "disable_linear" option. This is functionally similar to combining multiple "libplacebo" filters, but does not rely on the existence of a Vulkan filter link, so it can be used without performance penalty in all circumstances. It's also enabled by default, without requiring special action from the user.
* avfilter/vf_premultiply: use correct premultiplication formulaNiklas Haas7 days1-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous formula was introduced without justification in 6e713841e8, and the only thing Paul had to say about it over IRC was that it was copied from an unspecified source on the internet. I decided to do some testing and came to the conclusion that this term not only produces "illegal" files, but also lowers PSNR score, over the naive implementation without this extra term. Here are the results of a round-trip test, using allrgb/allyuv (respectively) as the input, and fade=alpha=yes:n=256 to cycle through every possible alpha value, comparing the round-trip output against the input: Before patch: PSNR r:26.677431 g:26.677431 b:26.677431 a:inf average:27.926818 min:6.012093 max:55.400791 PSNR y:26.677431 u:21.101981 v:21.101981 a:inf average:23.548981 min:9.013835 max:53.182303 (full) PSNR y:27.348055 u:21.101981 v:21.101981 a:inf average:23.625238 min:9.554991 max:45.652221 (limited) After patch: PSNR r:27.321996 g:27.321996 b:27.321996 a:inf average:28.571384 min:6.012093 max:52.424553 PSNR y:27.321996 u:23.187879 v:23.187879 a:inf average:25.431773 min:9.013835 max:50.199232 (full) PSNR y:27.868544 u:23.187879 v:23.187879 a:inf average:25.515660 min:9.554991 max:45.078298 (limited) It's worth pointing out that previous version sometimes artificially inflates PSNR by producing values that are too high (i.e. RGB > A), such as for the input pair (R = 255, A = 2) which should give R = 2, but actually gives R = 3 under the old logic. As a second evaluation without this shortcoming, here is a comparison against the reference value computed with a floating point format: Before patch: PSNR r:53.600599 g:53.957833 b:53.540948 a:inf average:54.945316 min:50.508901 max:inf (premul only) PSNR r:30.734183 g:30.734183 b:30.734183 a:inf average:31.983570 min:12.058264 max:inf (round-trip) After patch: PSNR r:61.751104 g:65.239091 b:61.339191 a:inf average:63.710714 min:55.441130 max:inf (premul only) PSNR r:32.611851 g:32.611851 b:32.611851 a:inf average:33.861238 min:12.058264 max:inf (round-trip)

| | | | | | | | | | | | | | Instead of scanning backwards for the end of RPU payload, parse it and report if we didn't land at the terminator byte. Current expectation was that we can have additional zero bytes after RPU payload, which were skipped to find playload end. That's not always the case. So loosen this requirement.
