What is the exact reason of this warning in ffmpeg

Thread message queue blocking; consider raising the thread_queue_size option (current value: 8)

Im sending through the pipe yuv420 video to ffmpeg and streaming to youtube. When warning appears i get fps drops. Increasing value will help for a while.
