avcodec/nvenc: unify CBR filler data insertion for all codecs - Cameron Gutman git.videolan.org Git - ffmpeg.git/rss log

avcodec/nvenc: unify CBR filler data insertion for all codecs Previously, AV1 used filler data with CBR by default while H.264 and HEVC may or may not depending on driver version. Make this consistent by using not filler data in CBR mode for all codecs. Since there are valid reasons to use CBR with or without filler, also add a cbr_padding option to allow users to override this.

tests/checkasm: fix wrong summation of bench time - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

tests/checkasm: fix wrong summation of bench time This was changed 8 years ago with the introduction of the linux-perf path, with seemingly no justification at the time. Likely a developer oversight from testing. This bug not only made --runs completely ineffective, but also meant that we didn't actually correctly filter out outliers.

avcodec/raw: Duplicate raw_pix_fmt_tags into fourcc2pixfmt tool Do this instead of exporting raw_pix_fmt_tags via avpriv_get_raw_pix_fmt_tags(). For shared builds this will lead to an increase in the combined size of the lavc and fourcc2pixfmt binaries (because the overhead of exporting avpriv_get_raw_pix_fmt_tags() is dwarfed by the size of the array), but given that fourcc2pixfmt is a test tool that is not widely distributed it does not really matter.

avcodec/ppc/mpegvideo_altivec: Don't process coeffs as scalars block_last_index and nCoeffs is an optimization designed to avoid processing unnecessarily many coefficients; yet it would be legal to always process all coefficients (all coefficients beyond nCoeffs are zero anyway and zeros are always unquantized to zeros).

On the encoder side complexity depends on how parameters are chosen. But with a fixed mul_count of 1 and basic heuristic it performs as well as any more complex choice i tried so far. The encoder code here is flexible and allows mul_count > 1 and also can easily be used to exactly test various parameters. With mul_count=512 we can gain another 6% in remap table size for fixed point in float data. (this is not implemented in this patch though) (...)

It then reads the 4 surrounding pixels, looks up 3 separate values for each in table1, adds them together to form an index into table2 for a new pixel value, in a row.

avcodec/mdec: Optimize processing escape codes - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

avcodec/mdec: Optimize processing escape codes Said escape code is only six bits long, so that one has at least 25 - 6 bits in the bitstream reader's cache after reading it; therefore the whole following 16 bits (containing the actual code) are already in the bitstream reader's cache, making it unnecessary to reload the cache.

hwcontext_vulkan: add support for mapping multiplane images into CUDA This patch refactors the CUDA import code to allow for Vulkan images with multiple planes to be mapped. Currently, a driver bug exists which causes NV12 images to be mapped incorrectly when the memory being mapped contains both planes, the issue has been reported to NVIDIA. yuv420p does work correctly, however. This is still an improvement, as the code used to crash when trying to map the memory, unless disable_multiplane=1 was given as an option. [DH] (...)

avcodec/codec_internal, all: Use macros to set deprecated AVCodec fields - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

avcodec/codec_internal, all: Use macros to set deprecated AVCodec fields The aim of this is twofold: a) Clang warns when setting a deprecated field in a definition and because several of the widely set AVCodec fields are deprecated, one gets several hundred warnings from Clang for an ordinary build. Yet fortunately Clang (unlike GCC) allows to disable deprecation warnings inside a definition, so that one can create simple macros to set these fields that also suppress deprecation warnings for Clang. This has already been done in fdff1b9cbfd8cf5a9810c29efa4baf13a4786742 for (...)

tests/swscale: constrain reference SSIM for low bit depth formats - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

tests/swscale: constrain reference SSIM for low bit depth formats Sometimes, the reference SSIM is significantly higher than the SSIM level expected for the test. This is the case when the source format has a much lower bit depth than the destination format. In this case, the fact that legacy swscale does not accurately preserve the source dither pattern gives it an unfair advantage in a direct comparison, leading to false positives. For example, conversion like rgb4 -> rgb565 should be lossless, but swscale low passes / downscales the input chroma, throwing away massive amounts of (...)

avutil/attributes_internal: Add EXTERN macro for extern+hidden - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log

avutil/attributes_internal: Add EXTERN macro for extern+hidden This is inspired by the equivalent dav1d attribute introduced by Henrik Gramner in e4c4af02f3de5e6cea6f81272a2981c0fa7bae28. Also already use it to beautify declarations.

vulkan: take refs of frames using the regular buffer ref path - Lynne git.videolan.org Git - ffmpeg.git/rss log

vulkan: take refs of frames using the regular buffer ref path This simplifies the code, reduces allocations, and critically, does not store references of frames, along with references to hw_frames_ctx. The issue was that storing refs to frames while transferring stored refs to hw_frames_ctx of frames, and so created a circular dependency, which caused the Vulkan device to never be terminated. This only stores what it strictly needs as a dependency, and enables the frames context to be freed, even while doing asynchronous transfers. [DH] (...)
