I'm perpetually impressed by the value FFmpeg adds to society. I imagine an accurate tally of all the places it's used would be impossible, but I can't help but imagine it would be eye-opening in it's breadth. Two noteworthy items that stand out to me: > AV1 Low overhead bitstream format muxer > speex decoder Congrats on the 5.0 milestone to all contributors!

On a current project I needed to get RMS volume of the mids of an audio file in 1-second isolated segments. I wrote a bunch of code to do just that...and was floored when my partner pointed out to me that ffmpeg could give me that exact data on the commandline.
