Unfortunately the World Wide Web did not have a built in language for video back when it was created, so web browsers were unable to play or embed videos without a third party plug-in/software application. Now with HTML5, you are able to add native video to your web pages without needing a third party software installed onto your computer/web browsers.
There are three main formats that all major browsers may support and they are: WebM, MP4, and OGV. Not every browser will support all three, so it is important that you add in multiple sources within the language coding for your video file, so that the browser can look in more than one place if the first one in the list does not work or is not supported. Here is an example of a single source:
In order to embed the video file into your web page you will need to use the video element attribute. Within this tag you will have a SRC or source attribute, which is where the web browser will look for the video. Within the video element, you can specify the and of the video and then close it off with a element attribute.
Within the video elements attribute, you can add in a controls option so that the browser will playback the video using the default controls. If this is not inputted then the browser may not use any controls at all, and thus the video will not have a play, stop, pause control mechanism. In addition to this, you can add in a attribute within the video element to have the video automatically be looped by the browser. Here is an example:
If you want to have a promotional image or picture that the user sees prior to hitting the play button on the video controls, then you can add in the attribute that will input an image to be displayed in place of the video until the video begins playing. If you do not specify this, then the browser may fill it with the first frame of the video, or a black box. Here is an example of the poster attribute:
HTML5 will allow a lof of web developers and people who code their own web pages to add in native video without requiring a third party application. All major browsers will support at least one of the three format options, and will have fall backs such as Flash if required.

I would use jQuery and the html5 canvas element, but I would have the user draw the shapes using straight lines. They click the line image, select two points and jQuery draws the line. Having the shapes drawn in jQuery will allow you to store them, to allow you to easily add the metadata, and package the data serialised in a db for future use, or store as an image, whatever you wish.
Note: You may have to run Xcode and install the various command line tools it install with it. I'm working on the assumption that if you're making GameSalad games you'll already have done that.
Although GameSalad has an HTML5 preview engine build right into the Mac app, it doesn't give an entirely accurate view of how projects will look and play. The two most prominent differences are the lack of custom collisions and the lack of custom fonts.
Now we need to run the server from within your game's folder. I just published and downloaded a copy of my game Sand, so we'll need to navigate to that directory. Doing this in Terminal is really easy.
I can either type the full path of the folder in, or I can drag the folder onto the Terminal window. Either way, I'll end up with the following, since the folder for my game is still in my Downloads folder:
Note: If you renamed your "sample-index.html" file to "index.html" you'll be taken directly to your game when you load up "localhost:8080" in your browser. If you didn't, you'll be shown the directory listing and can click on "sample-index.html" to be taken to your game.
macOS features a handy function called Quick Actions. These actions can be run on any folder or file in Finder. To access them, you just need to right click/command-click on any folder or file in Finder. If you have any quick actions, you can just click on them and they'll be run with the selected folder or file as the input.
I made a quick Quick Action to let me run the web server this way. So all I have to do is right click on the game's folder, select "Web Server" from my Quick Actions, and then tab back to my web browser to test.
Then you can save your new Quick Action, naming it whatever you want. Once you're done, it can be accessed through Finder any time you want. Super quick HTML5 testing with no uploading to a server is then yours to use!
Another great option. This one doesn't require anything to be installed and should work out-of-the-box on all Macs, and doesn't require the game to be put in any specific folder - the server runs from where the game is.
You can do that by publishing your game, then going to creator.gamesalad.com, and then importing the game from your published projects. When you preview in the web creator, you'll see the most accurate HTML5 preview.
I didn't know about @adent42's approach and perhaps it is better, but when I was developing games for Legends of Learning I needed a local server for their test harness and MAMP fitted just fine. All my 3 games currently live on LoL were developed with GS and tested with MAMP.
I did another HTML5-focused project recently and did a lot of previewing so ended up editing my Automator script to be a little more robust. Now it opens Terminal if it isn't open and will make a new window to run in. If any mod would like to edit it into the second post, that would be appreciated! Still probably not the most efficient way to do this but saved me a ton of time with testing!
The first edition of this book was written in 2011 based upon the latest W3C Candidate Recommendation of the HTML5 specification. That is to say, the unfinished specification. In fact, HTML5.0 was not finalised until the full W3C Recommendation was released on October 28, 2014. Some features were added and some lost during the interim period. This meant that some items in the first edition of HTML5 in easy steps were obsolete, and some were missing.
This second edition is based upon the full W3C Recommendation of the HTML5.1 specification that was released on November 1, 2016. This means that ALL features of the latest specification are accurately included and fully demonstrated in this second edition of HTML5 in easy steps.
HTML5 in easy steps, 2nd edition instructs you how to employ the latest development for web page design with HyperText Markup Language (HTML5). Modern web browsers have united to support exciting new features of the HTML5 standard that allows easy creation of stunning web pages and engaging interactive applications.
HTML5 in easy steps, 2nd edition has an easy-to-follow style that will appeal to anyone looking to create compelling web pages for the latest browsers. Ideal for programmers who need to quickly learn the latest HTML5 techniques, students learning website design at school or college, those seeking a career in web development who need a thorough understanding of HTML5, and the enthusiast eager to build the latest HTML5 features into their websites.

I'm planning on venturing on making a single player action rpg in js/html5, and I'd like to prevent cheating. I don't need 100% protection, since it's not going to be a multiplayer game, but I want some level of protection.
The short answer is you can't do it. Anything that runs client side, especially from source, can be modified to defeat your tactics trivially. If you put in place a client side checker to look for abrupt changes, a user can just disable the checker.
The good news is that, generally, there is very little cheating on single-player games. The only major exception being for games that have large "youtube highscore" communities like Line Rider, where players compete with each other over YouTube.
If you are aiming for that, or are just too stubborn to accept that people might cheat in the game, or are keeping high-scores yourself (which is a form of multiplayer) then what you must do is all of the calculations server-side. Yes, everything that matters. You can't even repeat the calculation client side to try to give the user the score and then 'verify' it with the server because the user can then just disable the check and disable any system that ensures there are checks.
So. As you see, it is probably not worth it to go this route. It is hard. Requires a lot of really silly coding practices to do, and is ultimately still relatively easy to defeat. You'll need to do all the calculations server-side to prevent cheating. Or let go, and accept that cheating will happen.
Is the baddest thing you could have say here. If you wanna do an "anti-cheat" engine, you'll have to do that. You can add anything you want client-side, to facilitate the server-side work, but you must never trust the client.All Logic you have must be at least server-side. You can reproduce it client-side if you want, but no client-side only solution will do it.
This "prevents new properties from being added", "prevents existing properties from being removed", "prevents existing properties, or their enumerability, configurability, or writability, from being changed"; any changes to the internal state should be done through accessors. The following example works on chrome (should work on firefox, I dont know about IE though...):
