<div dir="ltr">Hello, I'm writing an application to watch DVB-T tv. I'm using the dvbsrc and the flutsdemux elements. Unfortunatelly, I can't get the sound and video in sync: the sound is always a bit late. This is the pipeline I came up with: gst-launch -v dvbsrc do-timestamp=true modulation=AUTO trans-mode=AUTO bandwidth=AUTO frequency=586000000 code-rate-lp=AUTO  guard=AUTO hierarchy=NONE pids=16:17:18:110:120:130:140 ! flutsdemux  name=demux program-number=257 !  queue max-size-buffers=0 max-size-time=0 !  mpeg2dec  ! xvimagesink sync=false  demux. ! queue max-size-buffers=0 max-size-time=0 ! mad ! alsasink sync=false  I got there using some source files from flumotion, but I am a bit stuck now. I tried to tune various parameters such the "slave-method" and  "provide-clock" of the alsasink. I also tried to change parameters on the dvbsrc. This improves synchronization a bit, but the result is never in sync. After all those trials I thought that I probably do something wrong. Thank you for your help, Julien </div>
