I have to create an application using SDL Tridion 2013 (without DD4T). I want to use SDL Media Manager to manage the images and video contents for my application. Now the issue is I am able to retrieve the CDN url of MM items from application but unable to resolve it.
Please suggest what are the possible way to handle this situation.
If for whatever reason you want to "resolve" a Media Manager distribution URL, i.e. you want to get the redirected URL, you can achieve this with the following code snippet:
var distributionUrl = "http://blah/blah";
var request = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(distributionUrl);
request.AllowAutoRedirect = true;
var response = request.GetResponse();
var resolvedUrl = response.ResponseUri.AbsoluteUri;
When in the CM, you can use the ECL API to check the IContentLibraryMultimediaItem.DisplayTypeId, this will tell you if the item is actually an image or a video (or audio, or download item).
For DXA we are planning to add full support of Media Manager items in the upcoming version 1.2, which means we will add full ECL support in DD4T as part of that process. You can follow the progress on that via our GitHub fork https://github.com/sdl/DD4T.TridionTemplates/tree/feature/ecl-data
Now since you indicate you are not using DD4T, you will have to sort this process out yourself, but could probabaly use some of the approach we do there.
I think that using the distribution URL in an img src attibute will work just fine, no need to "resolve" the url.
You can also get the JSON output of the distribution if you want to parse it and get a thumbnail or specific renditions of that image (if those have been configured in media manager). For that, just replace "Distributions/?o=" by "json/" in the distribution url to get the JSON output. It is typically used to create custom media galleries, add effects on videos, create a custom video player and more.
