dumy stream when there is no data
Posted: 02 Jul 2011 17:08
Hi all,
I am in a very bad situation in a project. We use vlc as TV(DVB-S) streamer in a mobile system. VLC reads from receivers and streams as http stream to players like below.
vlc --programs=1 dvb:// --dvb-adapter=2 --dvb-voltage=18 --dvb-srate=7200000 --dvb-frequency=11973000 --sout '#duplicate{dst=std{access=http,mux=ps,dst=:20014},select="program=1"'
Sometimes antenna on top of the vehicle can't see satellite so there is no data for 1-2 seconds. On the player side this is a big problem. I have to restart player for every data loss. Player starts for 7-10 seconds. On player I couldn't use vlc, I have to use gstreamer. It is embedded platform and has hardware decoder. I couldn't build vlc for using hardware decoder.
So for 2 seconds data loss I have to restart gstreamer and it takes about 8-10 seconds. It is very bad.
In the roads there are a lot of obstacles for little data loss, bridges, trees, buildings....
Can VLC stream dummy data (maybe blank screen that has "No Signal" message) if there is no data on receivers?
So thanks
Mehmet Kurnaz
