The reason for the black screen is because of the "Video Acceleration Function (Overlay output)".
To solve the problem, please see the below instructions.
While Bandicam is running, Bandicam shuts off the overlay output.
If Bandicam is running, the streaming videos will not be played through the overlay output.

If the problem cannot be resolved by running Bandicam prior to the streaming video, then the video acceleration function needs to be shut off directly to resolve the problem in Windows XP.
When you click the right mouse button on the main screen of the computer, and click the 'Properties' option, then the overlay registration information will be shown.
When you go through 'Display Properties > Settings > Advanced > Troubleshoot, you will reach the option for setting the acceleration for the hardware.
This option needs to be set to 'None' and then, the 'Apply' button needs to be clicked in order to process the recording through Bandicam normally.
