Heydon is back with a new project named “Webbed Briefs”:
WEBBED BRIEFS are brief videos about the web, its technologies, and how to make the most of them. They’re packed with information, fun times™, and actual goats. Yes, it’s a vlog, but it isn’t on Youtube. Unthinkable!
The first video is entitled “What Is ARIA Even For?”, and indicates where this is headed: tons of information, fast paced, lots of mindfarts, and quite a lot of cursing …
Next to praising the AV1 Codec and providing conversion examples (using ffmpeg), Andrey Sitnik also gives a good overview on containers and codecs – concepts every web developer who embed video should know imho – in his post on the subject:
File extensions for video (.mp4, .wmv, .webm or .mov) barely represent containers. When you see a .mp4 extension, the only thing you can be sure about is that the MP4 container had been used to package a file. The choice of codec depends entirely on a creator: it can be H.264/AAC, or AV1/Opus, or something else.
