So in my case in FFmpehframeGrabber#720 which is

  if ((ret = avformat.avformat_find_stream_info(this.oc, (PointerPointer)null)) < 0) {

block for several seconds. Is there any way to suppress that call on native level (as in java code shows there is none) by eg providing some stream info before starting capturing? I will be using only single format stream so I can provide as much information beforehand as API allows me.
