Why my Helios Backup switcher is having v/a sync issues, glitches or randomly cuts the stream?

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.
