Currently app_transcoder does not support mjpeg decoder, it could support it easily, but you would also need to patch asterisk to support it. The delay introduced by the app_transcoder is minumun, jsut the cpu time needed to decode and re-encode the frame, so it varies depending on the video codec, cpu and size of the frame.
