Nice application!

For some unknown reason, the "localhost" part does not seem to
work anymore. When I just use ":0.0+100,100", it works fine.
Perhaps you have the same problem?

libdc1394 is only necessary for Firewire cameras.

That's strange. Maybe Bino does not link to your self-built FFmpeg
libraries, but to some system libraries? Can you check with
"ldd ./bino"? You can force linking to your FFmpeg version with
./configure PKG_CONFIG_PATH=/path/to/your/ffmpeg/lib/pkgconfig ...
