Does this always happen? Specific video or any video?

[karnauskas]

Not always. I have tied with a few mp4 videos and the same behavior. I noticed it doesn't crash if I change zoom factor to 1 (-v -q -d 2).

I use -i file.mp4 -o file-new.mp4 -v -q -d 2 as parameters by default.

[TianZerL]

How about set zoom factor to 1.99 or 2.01 ? And how about -w to enable ACNet?

[karnauskas]

-z 1.99 -w failing, -z 1.9 -w works, -z 2.1 -w works, -z 2.1 failing

Thank you very much for your feedback. Since I can't reproduce your problem on Linux or windows at present, the problem may be caused by a third-party library. Please post the output content of ./Anime4KCPP_CLI -V to better analyze the compilation parameters and library usage. I will continue to investigate possible problems.

And if possible, I hope you can help find the function or library that caused the crash by using tools such as gdb or lldb or Valgrind

[karnauskas]

It's on mac actually. Will have a look at lldb when have time.

Thank you! As I currently don’t have a mac environment, I can’t debug it myself for the time being. I suspect Apple's OpenCL library may have caused the problem. Is there a problem using the CPU? And you can try to turn on Use_Legacy_OpenCL_API CMake option, which will set the target platform of OpenCL to version 1.2, which as far as I know, the version currently supported by mac.
