FFMPEG assumes video framerate is always 25fps

[jacobkeeler]

Bug Report

When performing video streaming via the HMI, ffmpeg seems to always assume that the app is sending 25fps video, regardless of the actual input framerate. The HMI should be able to determine the framerate from the video source itself

Reproduction Steps

1. Start video service with 10fps video from Android app

Expected Behavior

Video begins streaming in HMI, video plays at 10fps

Observed Behavior

HMI attempts to play the video at 25fps, causing significant stuttering

Browser & Version Information

• Browser and Version: Chrome Version 100.0.4896.75
• Generic HMI Version: master
• Testing Against: Android Test Suite
