Users should remember that the Backup Switcher will only work properly if:
- Each input has identical video properties: codec, resolution, pixel format, codec profile, and level;
- Only AAC audio is supported at this time;
- If the B-frames are present in one input, they have to present in the Input 2, too.
e. g. Input 1: B-frames + Input 2: B-frames = good
Input 1: B-frames + Input 2: without b-frames = v/a sync issues, glitches, etc.
