Now that newer version of gcc default to c++17 avidemux fails to build with a bunch of errors like:

I have forced the RPM Fusion package to use C++14 for now but would like to get it fixed.

Thanks,

Thanks, looking into it.

Should be fixed now, with a followup added to make friends with Apple clang which else seems to default to C++98.

BTW, 2.7.7 is expected soon, it may be worth waiting a few weeks for the release rather than adding patches.

I can confirm that fixed it for me. Looking forward to 2.7.7.

Thanks,
Richard
