How to get filename(with extension) of Video file in callback of AssetPickerConfig

Question

Now it returns only filename without an extension. Content type of file is Video.

The name of file contains only file name without an extension in the Asset dialog.

Is it possible to get filename.extension ?

with(new AssetPickerConfig('testAssetPickerObj'))
{{
     DefaultAssetImageLocation='';
     CurrentWebBaseUrl='https://xxx/';
     OverrideDialogFeatures='';
     OverrideDialogTitle='';
     OverrideDialogDesc='';
     OverrideDialogImageUrl='';
     AssetUrlClientID=NWF$("#" + txtURL).attr('id');
     AssetTextClientID='';                                                             
     UseImageAssetPicker=false; //make this false to show Documents instead
     DefaultToLastUsedLocation=true;
     DisplayLookInSection=true;                                                             
     ReturnCallback = getFileNameCallback;}}

function getFileNameCallback(dialogResult, returnValue) {
    console.log(dialogResult, returnValue);
}

It should be CLIP_11.mp4

Answer 1

Finally I resolved it.

As a video (Content type: Video) is stored in the asset library, they are stored as folders with folder name being the video name. What I am getting is only the name of the folder. The properties (URL, full name) and the video itself are stored within the folder as another content type known as Video Rendition. Getting the actual video can be done using REST api with the following url:

http://siteurl/_api/web/GetFolderByServerRelativeUrl('/Video Name')/Files

---

function getFileNameCallback(dialogResult, returnValue) {

    $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + '/_api/web/GetFolderByServerRelativeUrl(\'' + dialogResult + '\')/files',
        method: "GET",
        headers: { "Accept": "application/json; odata=verbose" },
        success : function(data){ //data will have the video object
            var videoServerRelativeURL = data.d.results[0].ServerRelativeUrl;
            console.log(videoServerRelativeURL);            
        },
        error : function(args) {
            console.log(args);
        }
    });
}
