What Hacker News says

3 sources
m4b-tool - merge, split and edit audio books (https://github.com/sandreas/m4b-tool/) This one has become pretty popular in the meantime - did not expect that :-) --- graft - file transfer utility with regex, mdns and sftp server (https://github.com/sandreas/graft/) Designed to have tools like find and copy also on Windows - not maintained any more, since I found sfk, rclone and others... --- look - a log file watcher (https://github.com/sandreas/look) Designed to have tail on windows, not maintained any more, because its ready for my use case. --- pilabor - a hugo blog to manage my personal notes (https://pilabor.com) Started as an experiment a few month ago for organizing my personal notes in a hugo project. Worked out pretty well so far.
In Ask HN: Tools you have made for yourself?
I use ffmpeg for encoding audio and metadata extraction... very powerful and a really sophisticated tool, but handling timestamps I agree with you. Some caveats that I came across along the way: - Inaccurate time handling (https://github.com/yermak/AudioBookConverter/issues/21#issue...) - Incorrect handling of mp3 chapters https://github.com/sandreas/m4b-tool/issues/71#issuecomment-... If anyone who is interested in using ffmpeg in a docker container (without the dependencies / compiling stuff), this alias is pretty useful (with relative paths ;-): alias ffmpeg='docker run --rm -u $(id -u):$(id -g) -v "$PWD:$PWD" -w "$PWD" mwader/static-ffmpeg:4.3.2'
In FFMPEG from Zero to Hero
