To deliver video from your phone to Mac in real-time, EpocCam utilizes video compression. Before displaying video in macOS it needs to be decompressed.
The 'Software' decompression option uses the computer's CPU to process the video, and the 'Hardware' decompression option uses a dedicated hardware GPU, either discrete or built into the CPU.
We recommend using the 'hardware' option for best performance. However, if you experience issues with video quality, try 'the Software' option for best compatibility.
