To increase the volume by 10dB:If we specify a smaller -bufsize, ffmpeg will more frequently check for the output bit rate and constrain it to the specified average bit rate from the command line. Hence, lowering -bufsize lowers the bitrate variation that the encoder can produce. Specifying too small -bufsize would cause ffmpeg to degrade the output image quality, because it ...
