I read at the link that yt-dl uses ffmpeg and doesn't endorse avconv. Just curious if this is the place to ask, Does anyone know what the differences are between avconv and ffmpeg? Do they still basically do the same thing, or is there any reason to use one over the other. I remember years ago reading that one was a fork due to a disagreement or something, but I don't know how things have come along currently. I've mostly exclusively used ffmpeg any time I needed to convert a video, or more commonly for my use case, converted a directory full of images to a video.
