fix: upscale and division by zero issue

[murat-mehmet]

Summary

We use maxSize to downscale larger videos but smaller videos will also be upscaled to the maxSize in auto compression.
Also there is a division by zero issue when calculating min bitrate. It happens when getVideoBitrateWithFactor is divided by a number < 1. We need to first cast the result to float, make the division and then cast it back to int.

fixed upscale and division by zero issue

Test Plan

• Try to auto compress a video with maxSize higher than the actual size of the video.
• Try to auto compress a 1080 x 1920 video with maxSize: 8000
