[Freeswitch-users] record_fsv buffers - Any way to flush incoming video?

Hi folks - I have a freeswitch dialplan + script that first calls play_fsv to play a greeting, then record_fsv to record incoming video to fsv. It works fine, but there's one issue: Apparently, freeswitch is buffering incoming video during play_fsv. When record_fsv is called, that buffer is dumped into the .fsv file, resulting in several seconds of unneeded video. Is there a way to empty that incoming video buffer before record_fsv begins recording? Thank you! - Greg Millam
