I am puzzled by the performance of my Studio DC10plus capture card. using lavrec (from mjpegtools-1.6.1), I don't LOSE frames, but frames do get INSERTED - at the rate of 15 per hour. I have played with buffer_size and buffer_number; and also with quality of the capture video. I don't see any noticeable A/V sync errors, but I am curious as to why these extra frames arew being inserted. Are you able to answer this for me?
