Description

Hello, Is it possible to change the video bitrate and fps while recording on the fly without realeasing and restarting the recorder? I tried to to so but the bitrate and the fps stays the same.

Contributor guide

Research direction
Examine the FFmpegFrameRecorder source code in JavaCV to see if it supports changing bitrate and fps during recording; if not, investigate FFmpeg's native API for dynamic parameter changes.
