Dear Dominik

The right solution is always to make the ffmpeg directly compatible with FreeBSD (of course, along with other supported OSs). That is, just download the ffmpeg, run configure with once's required options and make and make install.

Right now, thanks to ffmpeg developers, ffmpeg is "directly" compatible with FreeBSD 8. This is a good thing, which benefit larger number of FreeBSD users whether they use FreeBSD port system or not.

Please note, FreeBSD OS and its default port system are two different things. It is not mandatory to use the FreeBSD port system on FreeBSD.

Hope, you have noted, I just compiled and installed ffmpeg with options that I want. I did not wait until port maintainers to upgrade it.

By making any software directly compatible with FreeBSD or any other OS, you make users do not have depend on their port maintainers.

Best regards
