I am  trying to retard the video from an apple tv  to deal with the audio convolution filters  delay of about 600 ms
I am passing apple tv through  the black magic card and using wirecast to delay the video.
However I can't get the blackmagic to play audio directly through JRiver
When I go to open live and configure the asio line in to black magic audio it shows playback problem

I can get wirecast to connect to jriver and play sound bit only after it has been delayed the same as the video
Appreciate any help

Did you try JRiver's VideoClock?

[mattkhan]

videoclock isn't relevant here

I take it you've tried to use jriver television support for that device and that doesn't work either?

does blackmagic provide an asio output device? I wasn't aware of it having such capability so typically you'd either use some asio bridge (like VB Audio Matrix) or use the jriver wdm driver to loop audio back into jriver

I have to say I'm going to be pretty surprised if you can get that synced reliably but good work if you do!

I hadn't tried television as I am sending video out via wirecast through black magic but I can try it

I can get sound via wirecast but the video delay I need doesn't  work .. I can't get any sound out of OBS either
I was  wondering if neither stripped out the apple coding

I can try an intermediary program  and see how that goes
Thanks for your advice
