If you are not seeing the recording button, then this can have one of the following reaons:
- the channel is not configured properly, please make sure that there is at least one valid capture- and destinaton-preset set
- or the channel is in schedule mode and there is no recording button as the recording starts an stops automatically
In case the communication between the engine and the UI is slow, the recording button will dissappear frequently. Lower the number of channel connections or the size and/or the frame rate of the previews to solve the problem.
