From fa98e594220b86eb3632de478352e93ebf1201fa Mon Sep 17 00:00:00 2001 From: Mike Isely Date: Mon, 26 May 2008 05:54:24 -0300 Subject: V4L/DVB (7938): pvrusb2: Increase enforced encoder wait delay to improve reliability The driver enforces a "quiet period" on the encoder in certain situations before attempting to operate it. This seems to help avoid video encoding errors / corruption. The quiet period was 50msec, but through experimentation it has been observed to improve further if the interval is increased to 100msec.
