From ac4251445d7302697814351f1d9f548f5aa49342 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 22 Jul 2007 08:46:38 -0300 Subject: [PATCH] V4L/DVB (5916): ivtv: fix pause/continue/play handling Pausing a decoder followed by a Play command would do nothing. Fixed. Pausing a decoder running at non-standard speed following by a Continue would reset the speed to 100%. Fixed.
