Given that Flash is being minimally maintained for linux, it's nice that Youtube has gon over to HTML5, but there are still a few hiccups that I ran into. I'll detail how I got around them, and also mention random access to videos. For the purposes of this example, I'll use the "Ancient Aliens Debunked" video, because it's over 3 hours long, which allows for examples of time offset. Warning... some URL-tweaking follows. Item 1) Youtube is now "officially" viewable in html5 without Flash, but I do run into a few instances of... ======================= X This plugin is disabled Manage plugins... ======================= Here's a video that "doesn't play on HTML5". https://www.youtube.com/watch?v=j9w-i5oZqaQ&hd=1 Let's break it up into sections. For URLs, the first parameter is preceeded by "?", and additional parameters are preceeded by "&". https://www.youtube.com/watch?v=j9w-i5oZqaQ&hd=1 breaks up into https:// www.youtube.com domain /watch "watch" parameter ?v=j9w-i5oZqaQ video ID &hd=1 HD mode selection If you get rid of the "&hd1", the URL becomes... https://www.youtube.com/watch?v=j9w-i5oZqaQ ...and it plays perfectly in HTML5, without Flash. Note that this is "the basic Youtube video URL". Item 2) OK, you've got a long video, and you want to jump a certain point in the video, without having to wait an hour plus to get to that point. This is done by appending a "&t=" parameter. It can contain "h", "m", and "s" subparameters. E.g. 1 hour, 20 minutes, and 15 seconds is signified by "&t=1h20m15s". You can include any or all of h/m/s. A few examples follow. "Pumapunku" (begins at 3 minutes 34 seconds into the video). https://www.youtube.com/watch?v=j9w-i5oZqaQ&t=3m34s "The Pyramids" (begins at 22 minutes 40 seconds into the video). https://www.youtube.com/watch?v=j9w-i5oZqaQ&t=22m40s "Easter Island" (begins at 1 hour 1 minute 35 seconds into the video). https://www.youtube.com/watch?v=j9w-i5oZqaQ&t=1h1m35s "Pacal's Rocket" (begins at 1 hour 5 minutes 43 seconds into the video). https://www.youtube.com/watch?v=j9w-i5oZqaQ&t=1h5m43s -- Walter Dnes <waltdnes@waltdnes.org>
