Umbraco V7xx Inserting HTML5 Video to webpage

Question

So I have created a document type in umbraco with corresponding template for my video section, which I want it to be content manageable and don't want to embed from youtube or similar. I have changed the upload limit for umbraco in webconfig and uploaded the vid in media section, using media picker. The problem I have now is how to fetch it from that media and display it on my home page. I have this code in my partial view, which is for that section but it's not display anything to the page and not showing any errors on the console:

Edit: I tried a new way, it's giving me this error: Object reference not set to an instance of an object. (as soon as I remove ".Url" the page works but it doesn't load the path to the video in media! :(

Answer 1

What have you tried to do yourself to fix? Could you check what HTML code is being generated? Have you tried debugging your way through? Are you getting a proper mediaFolderId? Are you actually picking a media folder on your content? What type of object are you then getting in the .Children() collection?

You aren't using your "video" variable in the loop, you are requesting a property of the current page instead. If you're lucky you might be able to do something like

src="@video.Url"

instead of the whole Model.Content thing, but it's very unclear from your question whether it might actually work :-/

EDIT: you should be able to do something like this to get a single Media URL:

var videoId = Model.Content.GetPropertyValue<int>("sowifiVideo");
var videoUrl = Umbraco.Media(videoId).Url;

and then

<source src="@videoUrl" type="video/mp4" />

When you do images and use GetCropUrl(...) then, funnily enough, that function gets the URL for you. With any other kind of media file you have to do it yourself.
