Now lets assume I want the same as above but limit the recording to 10 seconds. The following examples would satisfy that …

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, …Download binaries for ffmpeg, ffprobe, ffserver and ffplay (Windows, Mac, Linux)ffmpeg. ffmpeg -i input.mp4 output.mp4. 3.

42. When -ss and -t are placed before the input, ffmpeg resorts to fast seek which relies on the index of the input to allow ffmpeg to start and stop seeking. MP3s don't have indices, so ffmpeg estimates duration via bitrate. This can be inaccurate. When -ss and -t are placed after the input, ffmpeg counts demuxed packets. This will be accurate.
