On the backend it's all working, however, switching between channels doesn't quite work, as the streamdev server will give the client the same channel over and over again regardless of what it requested, unless the device changes (ie, if I go from /dev/video1 to /dev/video2 it'll change channel). > how do you force switching the video device?

I have no idea. It works for you with vomp. It worked for me with streamdev when I tested this last year. But I had only streamdev-server running and used vlc to switch channels. > > Maybe a streamdev developer reads this and has an idea or can explain possible > interactions between streamdev-client, vdr and a receiving device. > I think this is a streamdev issue not a pvrinput one, as if I change from channel 5 to 6 on the remote streamdev client it will continue to display channel 5. If both my tuners are busy then it will lock to channel 5 on my backend if I test it with xineliboutput. Not lock to channel 6. I had a look at the http::// streamdev playlist settings and it sees different channel pids. Streamdev to vlc would work as it breaks the streamdev connection when you change channel. But streamdev-server to streamdev-client doesn't seem to break the connection, just request a second channel as it releases the first. _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
