Is it possible to build OpenPHT with external FFmpeg on Ubuntu?
Someone created that option for Arch Linux using a modified PKGBUILD file. gist.github.com/congyiwu/6207793
I tried to build (on 14.04 and 15.10) with the option --enable-external-ffmpeg and -DUSE_INTERNAL_FFMPEG=off but both were ignored during the build.
