[FFmpeg-user] how do I list the devices?

[Ricardo Kleemann]

Hello,

Regarding the options for config/compile, I didn't follow any specific set
of instruction or logic, I took a script used for building ffmpeg on a mac.
I can certainly change the script based on your helpful feedback.

There's an app from Blackmagic (Media Express) which works fine with the
driver.

There's also the Flash Live Media Encoder (from Adobe) which recognizes the
blackmagic device and works well, so I can only assume the driver is
working fine.

Unfortunately neither ffmpeg nor VLC recognize the device so somehow to
these the driver isn't working, no idea why... :-/
