Description

I want to control the audio volume during playback. I found that the ffmpeg filter has a volume function, but it seems that the FFmpegFrameFilter cannot change the volume property after start(), because I need to adjust the volume in real time. What should I do

Contributor guide

Research direction
Investigate if FFmpegFrameFilter supports dynamic filter parameter changes after start() or if you need to recreate the filter graph. Look into FFmpeg's command filters like 'volume' and consider using an audio resampling approach.
