The progress cannot be extracted for sources that don't have a duration (e.g. https://sourceforge.net/projects/front4ffmpeg/, I contributed a small open source utility for showing progress bar on ffmpeg: I suggest to chnage function trans() call to this one: #call the conversion and fork it Eventually, after hours of googling, I came across the solution. It can also perform RMS-based normalization (where the mean is lifted or attenuated), or peak normalization to a certain target level. However, ffmpeg does NOT post the data every 1 second, but ONLY one time at the end of the encoding process. Currently, the script works well for the same type of video file, but for varied video files, it seems to have problems. ./progress.sh: line 88: syntax error near unexpected token `>’ When using ffmpeg to compress a video, I recommend using the libx264 codec, from experience it has given me excellent quality for small video sizes.
