Convert webm to mp4
There's an upcoming Mozilla trip to Hawaii on the cards and, in trying to be a good family man, I'm bringing my wife and two young sons. Glutton for punishment? Probably. Anyways, I've been feverishly downloading cartoons from YouTube using youtube-dl to put onto our new iPad to keep my oldest son occupied during the long flight.
It seems as though YouTube preserves the original video format, since sometimes youtube-dl provides a webm and other times a mp4. Since mp3s are iOS' best friend, I've needed to convert the webm files to mp4. The following ffmpeg command will make that happen:
ffmpeg -i "Spider-Man.webm" -qscale 0 "Spider-Man.mp4"
qscale 0 directive instructs ffmpeg not to adjust quality of the video during conversion. And with this conversion I can now properly transfer the videos onto my iPad.
