The ffmpeg configure script does not use the regular econf setup. It initializes an array of arguments starting with $EXTRA_FFMPEG_CONF, but then automatically determined options are appended after that. This prevents those options from being overridden without rewriting the ebuild's configure function. The $EXTRA_FFMPEG_CONF should be at the end of the configure command-line. Reproducible: Always Steps to Reproduce: 1. Run "EXTRA_FFMPEG_CONF=... emerge ffmpeg" to change some option that is set automatically. Actual Results: The specified options have no effect. Expected Results: User-provided options should be given the highest priority. I hit the problem by cross-compiling for a new triplet that is just optimized for the current system's native CPU. The ebuild checks CFLAGS and sets --cpu=host for the configure script. The script rejects the host CPU when it detects it's cross-compiling. That is an upstream problem, but I am unable to work around it by setting a target CPU since the custom --cpu= argument is ignored.
I'm willing to close this bug when this commit is in a release or backported, since it was the original issue that prompted this in the first place: https://github.com/FFmpeg/FFmpeg/commit/9f567c431eb49e5cd4399f54de433422f5b9b9c4
Well, this bug is still an issue, but I've corrected the underlying problem that prompted it upstream in 4.3. I'm just going to close this since there is apparently no interest or ability to fix it.
