• 【分享】FFMpeg checkout 版本n4.2.5,得到master版本, 导致后续OpenCV 4.5.4编译错误; 切换到指定远程分支,解决问题。


    对FFMpeg checkout 版本n4.2.5,实际得到master版本,导致后续OpenCV 4.5.4编译错误。使用“git checkout -b n4.2.hankf.01 remotes/origin/release/4.2”,解决问题,后续OpenCV编译成功。

        vf_paletteuse: fix color cache lookup for Bayer dithering mode.
    
        To trigger this bug, use `paletteuse=dither=bayer:bayer_scale=0`; you will see
        that adjacent pixel lines will use the same dither pattern, instead of being
        shifted from each other by 32 units (0x20).
    
        One way to demostrate the bug is:
    
        $ convert -size 64x256 gradient:black-white -rotate 270 grad.png
        $ echo 'P2 2 1 255 0 255' > bw.pnm
        $ ffmpeg -i grad.png -filter_complex 'movie=bw.pnm,scale=256x1[bw]; [0:v][bw]paletteuse=dither=bayer:bayer_scale=0' gradbw.png

        Now:        https://www.rm.cloudns.org/img/uploaded/89caaa5e36c38bc2c01755b30811f969.png
    
        This was caused by passing inconsistent color vs (a,r,g,b) parameters to
        color_get(), and NBITS being 5 meaning actually hitting the same cache node
        does happen in this case, but ONLY if bayer_scale is zero.
    
        The fix is passing the correct color value to color_get().
    
        Also added a previous-failing FATE test; image comparison of the first frame:

        (on this less synthetic test image, the bug basically causes noise from cache
         hits vs misses)
    
        Tested: FATE passes, which exercises this filter but at the default bayer_scale.

        The calling code does not handle failures and will fail with assertion failures later.
        Seeking can always fail even when the position was previously read.
