[FFmpeg-user] change inputs or mapping while recording

Hi,

FFmpeg would need to have been built with 0mq support but I'm almost sure there are windows versions of the library, client and server. Any way to send commands to a filter would work, you can sort of do it in the shell that's running FFmpeg (typing "c" brings up a command line) but it pauses everything.

Regards,
