Subject: tsdemux - PCR fix for ffmpeg input
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=edb391944c2dfd93c061674c3576ba6531e62f80;p=thirdparty%2Ftvheadend.git

tsdemux - PCR fix for ffmpeg input

The PCR clocking in the mpegts stream comming from the ffmpeg
is really ugly. There are up to 2 seconds gaps between updates.
