The settings will only be done if the bool ChannelSettingsDone is false. This bool is always false at first plugin start. I guess this is the reason why your channel settings were done once: > Jun 7 19:13:24 oac vdr: [8795] entering cPvrDevice::OpenDvr: Dvr of > /dev/video1 (PVR500#1) is closed > Jun 7 19:13:24 oac vdr: [8795] entering cPvrDevice::CloseDvr: Dvr of > /dev/video1 (PVR500#1) is closed > Jun 7 19:13:24 oac vdr: [8795] cPvrDevice::ResetBuffering(): tsBuffer > prefill = 314524 for /dev/video1 (PVR500#1) > Jun 7 19:13:24 oac vdr: [8795] channel is television. > Jun 7 19:13:24 oac vdr: [8795] OpenDvr: calling > /etc/vdr/plugins/pvrinput/externchannelswitch.sh 30040 4 1 67250 > Jun 7 19:13:25 oac vdr: [8795] OpenDvr: returned from > /etc/vdr/plugins/pvrinput/externchannelswitch.sh 30040 4 1 67250 > Jun 7 19:13:25 oac vdr: [8795] OpenDvr: sleeping for 3 seconds... > Jun 7 19:13:28 oac vdr: [8795] OpenDvr: waking up > Jun 7 19:13:28 oac vdr: [8795] SetVBImode(525, 0) on /dev/video1 When leaving OpenDvr, the bool is set to true. It will only become false again during runtime, if vdr calls the pvrinput- function SetChannelDevice() and determines the needed settings. And this is your problem. There are no debug messages from pvrinput's SetChannelDevice() or ProvidesChannel(), so vdr never calls these pvrinput functions - although a channel switch for a pvrinput device is requested. But why? 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. _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
