[Butterzeugs]

Hi,
i would like to stream on Twitch with my streaming software streamlabs OPS but i cant get it running.
I have some Annke Cams (Model:I41GD´2)
What i did try was this...

rtsp:/admincamip/H264/ch1/main/av_stream (as a new mediasource)
rtsp:/admincamip/HD1/ch1/main/av_stream?user=admin&pwd=

if i do this i get just a jpg pic...
