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"
The 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.

I love almost every part of being a tech blogger: learning, preaching, bantering, researching. The one part about blogging that I absolutely loathe: dealing with SPAM comments. For the past two years, my blog has registered 8,000+ SPAM comments per day. PER DAY. Bloating my database...
One event that's always been lacking within the document is a signal for when the user is looking at a given tab, or another tab. When does the user switch off our site to look at something else? When do they come back?
I was recently working on a project which featured tables that were keyboard navigable so obviously using cell outlining via traditional tabIndex=0
and element outlines was a big part of allowing the user navigate quickly and intelligently. Unfortunately I ran into a Firefox 3.6 bug...
We've always been able to create links with protocols other than the usual HTTP, like mailto, skype, irc ,and more; they're an excellent convenience to visitors. With mobile phone browsers having become infinitely more usable, we can now extend that convenience to phone numbers:

Hello,
Have a look at this : https://www.onlinevideoconverter.com/firefox-addon
This Grease adds a “convert” video to Youtube. Everything is processed on their server and it’s pretty fast !
What about using the
--list-formats
argument with youtube-dl and download the MP4 that suits your needs?Suggested code doesn’t work (10/22/17), Ubuntu 16.04.3 amd64
“The encoder ‘aac’ is experimental but experimental codecs are not enabled, add ‘-strict -2’ if you want to use it.”
It now says “Please use -q:a or -q:v, -qscale is ambiguous”.
I guess
-q:v 0
would be the new substitute.
