vulkan_vp9: Fix frame threading - Benjamin Cheng git.videolan.org Git - ffmpeg.git/rss log

vulkan_vp9: Fix frame threading The original cleanup of frame_id_alloc_mask was done in free_frame_priv which may be called after the start_frame for the next few frames, causing the frame_id slots to be exhausted. Instead, decide the in-use frame_id slots by checking the frame_id present in the DPB as we need it. [DH] libavcodec/vulkan_vp9.c

lavu/hwcontext_vaapi: fix a race mapping to allow CSC to YUV420P - nyanmisaka git.videolan.org Git - ffmpeg.git/rss log

lavu/hwcontext_vaapi: fix a race mapping to allow CSC to YUV420P There's a race condition for YUV420P when mapping from pix_fmt to VA fourcc, both I420 and YV12 could be found by pix_fmt. Currently, vaapi_get_image_format() iterates over the query results of pix_fmt and returns the first matching result in the order declared in the driver. This may result in an incorrect image_format. Now use fourcc to find the image_format. Fixes: ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i INPUT \\ -vf scale_vaapi=format=yuv420p,hwmap,format=yuv420p \\ -vframes 1 -f rawvideo -y yuv420p.yuv (...)

avfilter/vf_libplacebo: skip empty inputs - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/vf_libplacebo: skip empty inputs It is possible for pl_queue_update() to return PL_QUEUE_OK, but to generate an empty frame mix. This happens if the first frame of that input is in the future. In this case, we should skip an input as not active, similar to inputs that have already reached EOF. [DH] libavfilter/vf_libplacebo.c

avfilter/vf_libplacebo: whitelist properties on linear blend tex - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/vf_libplacebo: whitelist properties on linear blend tex Instead of copying over the entire target and changing a few fields, set the entire struct to a whitelist of safe properties that we want to persist on the intermediate texture. In particular, this avoids leaking irrelevant state related to the acquire/release callbacks, e.g., which can otherwise cause deadlocks when the same vulkan frame is attempted to be acquired twice.

avfilter/vf_libplacebo: use the first visible input for metadata Instead of undconditionally using the first input. This covers the case of one layer fully obscuring another layer, in which case that should become the new "base" layer. [DH] libavfilter/vf_libplacebo.c

avfilter/vf_libplacebo: flush render cache when input is invisible - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/vf_libplacebo: flush render cache when input is invisible This prevents leaking stale metadata from previous frames, for example if an overlay temporarily obscures this input and then un-obscures it again. It is worth pointing out that this does change the semantics subtly, because of the smoothing period on detected HDR metadata, but I argue that the new behavior is an improvement, as it will avoid leaking past metadata that is definitely no longer relevant after an image is unobscured. [DH] (...)

avfilter/vf_libplacebo: skip rendering fully invisible planes - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/vf_libplacebo: skip rendering fully invisible planes Sometimes, one input fully obscures another. In this case, we can skip actually rendering any input below the obscuring one. The reason I don't simply start the main render loop at `idx_start` will become apparent in the following commit. We can't use pl_frame_is_cropped() on this dummy frame, but we need to determine the reference frame before we can map the real output, so to resolve this conflict, we just reimplement the crop detection logic using the output link dimensions.

Revert "avformat/tls_openssl: properly get new BIO index" 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.

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.

avformat/movenc: fix HEVC fmp4 HLS init segment for Apple playback 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 (...)

Also, all check_* functions don't work as expected, because they assume the check passed, even though there was a warning.

avutil/hwcontext_vulkan: don't over-map buffers with prior padding If the image data is not at the start of the buffer allocation, such as when the buffer has padding before the image data, this function maps too much memory, since src_data + src_buf->size exceeds the buffer size. Fix this by subtracting the difference between the buffer start and the provided image data pointer from the size of the memory range to map. An easy way to reproduce this issue is using the vf_pad filter, which allocates image data buffers with a nonzero offset whenever padding is requested before the (...)

For 16-bit inputs, we could in theory instead use a pminw / pmaxw to ensure the resulting difference does not overflow, but this is slower, and also breaks the subsequent use of pmaddwd, so I opted to skip 16-bit SIMD for now. scene_sad10_c: 114175.6 ( 1.00x) scene_sad10_avx2: 9617.7 (...)

avfilter/vf_blackdetect: add AVX2 SIMD version - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/vf_blackdetect: add AVX2 SIMD version Requested by a user. Even with autovectorization enabled, the compiler performs a quite poor job of optimizing this function, due to not being able to take advantage of the pmaxub + pcmpeqb trick for counting the number of pixels less than or equal-to a threshold. blackdetect8_c: 4625.0 ( 1.00x) blackdetect8_avx2: 155.1 (29.83x) blackdetect16_c: 2529.4 ( 1.00x) blackdetect16_avx2: 163.6 (15.46x) [DH] libavfilter/vf_blackdetect.c [DH] libavfilter/vf_blackdetect.h [DH] libavfilter/x86/Makefile [DH] libavfilter/x86/vf_blackdetect.asm [DH] (...)
