ffprobe sometimes returns Programs.program.streams.stream.0.nb_frames for -show_entries stream=nb_frames, thus breaking progress tracking. I haven't figured out why. It's super annoying though.
Should use tail -1 or some such solution to always get the appropriate line. See the changes to getLength() in 8a25814cdf62cafff7b7aa9c3abfd2dd76d8d318 as an example.
