  • avcodec/hevc : reduce memory for SAO

    avcodec/hevc : reduce memory for SAO
    

    cherry picked from commit 5d9f79edef2c11b915bdac3a025b59a32082f409

    SAO edge filter uses pre-SAO pixel data on the left and top of the ctb, so
    this data must be kept available. This was done previously by having 2
    copies of the frame, one before and one after SAO.

    This commit reduces the storage to just that, instead of the previous whole
    frame.

  • aarch64 : vp9mc : Load only 12 pixels in the 4 pixel wide horizontal filter

    3 janvier, par Janne Grunau
    aarch64 : vp9mc : Load only 12 pixels in the 4 pixel wide horizontal filter
    

    This reduces the amount the horizontal filters read beyond the filter
    width to a consistent 1 pixel. The data is not used so this is usually
    not noticeable. It becomes a problem when the application allocates
    frame buffers only for the aligned picture size and the end of it is at
    a page boundary. This happens for picture sizes which are a multiple of
    the page size like 1280x640. The frame buffer allocation is based on
    its most likely done via mmap + MAP_ANONYMOUS so start and end of the
    buffer are page aligned and the previous and next page are not
    necessarily mapped.
    Under these conditions like seen by Firefox a read beyond the end of the
    buffer results in a segfault.
    After the over-read is reduced to a single pixel it's reasonable to use
    VP9's emulated edge motion compensation for this.
