and from source.
UPDATE: it finally came back up! Got the binary and used it.
To get a fully functional FFMEG from source: Make sure you have libtheora, ogg, vorbis, x264 already built/installed. (TODO: need to see what configure opts vorbis and theora need, just used defaults)
Note: I used --enable-shared on all builds where the README.txt from the plugin did not explicitly give a command.
Also needed http://liba52.sourceforge.net/downloads.html, and http://ffmpeg.arrozcru.org/wiki/index.php?title=Libgsm (NOTE: libgsm has a crappy makefile, so you need to build it shared manually AFTER the initial build. That cost me 30 minutes in the wee hours of the night.)
NOTE: Be sure to use the EXACT snapshot of x264 as documented, else there is a missing symbol and it won't be used. I wonder why such an old version? TODO: look into updating to the latest if some benefit.
Also DON'T USE latest: libdc1394-2.1.2.tar.gz -- but getting config error:
seems to be needed but this header is not available in the latest src. Must have been deprecated.
