  swscale/output: fix bilinear yuv2rgb chroma interpolation - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log
  swscale/output: fix bilinear yuv2rgb chroma interpolation These functions were divided into two special cases; one assuming that uvalpha == 0, and the other assuming that uvalpha == 2048. This worked fine for simple 2x chroma upscaling but broke for e.g. yuv410p, non-centered chroma, or other special cases that involved non-aligned chroma filters. Fix it by instead dividing this check into two cases, a uvalpha==0 fast path and a uvalpha>0 general path. Instead of (A+B)/2 the general path now multiplies in the true uvalpha weight. I tried preserving the old fast path for the case of (...)

It always returned the number of scaled lines, and continues to do so. To avoid confusion, but also avoid regressing possible clients that relied on the existing semantics, simply update the documentation to reflect the actual behavior. Remain ambiguous about the exact interpretation of the return value on account of the unfortunate difference in behavior between the legacy and new scaling (...)

  compat/w32pthreads: change pthread_t into pointer to malloced struct pthread_t is currently defined as a struct, which gets placed into caller's memory and filled by pthread_create() (which accepts a pthread_t*). The problem with this approach is that pthread_join() accepts pthread_t itself rather than a pointer to it, so it gets a _copy_ of this structure. This causes non-deterministic failures of pthread_join() to produce the correct return value - depending on whether the thread already finished before pthread_join() is called (and thus the copy contains the correct value), or not (...)

Due to the signature of the function, we cannot easily plumb the "true" width into the function body to perform a bounds check. Similarly, we cannot easily pre-pad the input because it is typically reading from the (const) input frame, which would require a full memcpy to pad. Either of these solutions are more trouble than the feature is worth, so just (...)

  avutil/csp: add EOTF function definitions 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 (...)

  hwcontext_vulkan: require storage properties to claim formats as supported This function dates back a long time ago, before vkfmt_from_pixfmt2. When it was converted over, the thought was that this was far too restrictive to demand storage images for each format. With the new clever function, it makes sure to check that the compatible subformats a format can be used as support storage capabilities. This gets rid of fake support for RGB48/RGB96 which some implementations offer but don't support using as storage images. [DH] (...)

  swscale: introduce new, dynamic scaling API 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 (...)
