hi Martin,

I frequently use the desktop capture function to capture powerpoint slides on a remote computer via wifi. I normally do not have any problems but since upgrading to vmix 12 i have two problems:

1. frequently loss of connection
2. drop outs - the screen capture is lagging behind.

I suspect it has something to do with the screen change detection. I notice that if a presenter does not forward a slide for sometime the chance the connection drops out is list. useually the connection is reestablished automatically, but sometimes i miss 1 or 2 slides or changes. similar to the drop out.

is there any change between v11 and v12? could it be possible to add an option to have a minimum connection at all times even if the slide /scree is not changed.

hope you can fix it because it gives a lot of stress recording a presentation and the slides do not progress or drop out.

greetings,
stefan

well I think I have found one likely cause and this is overcrowded wifi channels. I did not have any problems before but also noticed that iregularities in the stability of desktop capture over wifi varies over time. and with also people changing rooms where i record thus the signals will be variable. I decided to use a wifi channel tracker and check the usage of the different channels.

i changed my wifi modem to a free channel and i did not experience a loss of connection. after that.

because of increasing wifi traffic in public places and venues, it is therefor recommended to check the room where you record. i frequently record in different busy locations, at symposia and meetings and i use inSSIDer of metageek.net to check the trafic on the various channels.

greetings, stefan
