Starting with TV-Server build after 08/03/20 i get the message "Preview failed: NoVideoAudioDetected" when i try to preview a scrambled channel in tv-server. i use a cam + smartcard. The unscrambled channels work well.
As soon as i go back to the older version of tv-server all works well.
I attached the logs. May be somebody has an idea.
