[BUG] S905X (maybe all AMLogic?) HEVC decoding is flawed: bad image quality

  • All older builds are available at Index of /s905/old_builds

    But I highly doubt you will get different results than with the most recent builds.


    Another thing is that decoder microcode is closed source blob with no way to modify only a part of it. Porting whole microcode would most probably break decoding.

  • Is there a setting for sharpness (or similar) somewhere in the AMLogic Kernel?

    Let's hope it helps. :)

    If it does, we should also try to address the vertical lines in 2160p playback...

  • Unfortunately, I have not received any answer from Amlogic (yet).


    Does anyone have an idea how to fix or address this?
