Compiling this project with GCC 10.1, I run into multiple definition errors during compilation:

/usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: tcdemux-demuxer.o:(.bss+0x0): multiple definition of `gop_cnt'; tcdemux-demux_pass.o:(.bss+0x0): first defined here
/usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: tcdemux-demuxer.o:(.bss+0x4): multiple definition of `gop_pts'; tcdemux-demux_pass.o:(.bss+0x4): first defined here
/usr/lib/gcc/x86_64-pc-linux-gnu/10.1.0/../../../../x86_64-pc-linux-gnu/bin/ld: tcdemux-demuxer.o:(.bss+0x8): multiple definition of `gop'; tcdemux-demux_pass.o:(.bss+0x8): first defined here

I also see some "skipping incompatible [path to library]" messages, which are seen in #685522 . I don't know how that bug, if I'm seeing it here, relates to the multiple definition problem.

It looks like this should be fixed by https://gitweb.gentoo.org/repo/gentoo.git/commit/media-video/transcode?id=6228d70137eab7594520fe6e4dbd1a9a23bfe967

It looks like the original poster was using a version of the ebuild without the gcc-10 patch.
