This is dead according to upstream and fails to build with FFmpeg 6.0 Instead of patching I'd suggest removal and move to a project that's active, we've already spent too much time keeping it alive. Potential alternatives: https://github.com/lightspark/lightspark , https://ruffle.rs/ (neiter are in ports) or VLC References: https://git.savannah.gnu.org/cgit/gnash.git/commit/?id=583ccbc1275c7701dc4843ec12142ff86bb305b4 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261302#c46
Please go ahead and update FFmpeg. The port will be updated later.
