Update (24/01/2015): I have just got a word from Microsoft that there is going to be a public API for accessing Office 365 Videos.
The information I have got is that the API is not documented yet and is still being worked upon. So there is a possibility that it might change in the future so it is advised that this should not be used in production until it is fully stable and documented.
Here is a glimpse of the upcoming video API:

Original post follows:
In my previous post, we saw how you can get a list of all the video channels in your Office 365 portal with the REST API. In this post, we will see how to get a list of all the videos in a particular Office 365 Video Channel with the SharePoint REST API.
Each video channel is underpinned by a separate site collection in SharePoint Online. When you upload a video to a channel, it gets uploaded in the "Videos" library of the root web of that site collection. A copy of the video is sent to Azure Media Services which then transcodes it so that it can be played from a number of devices. Since the video is stored in SharePoint Online, the size of the video counts against your Tenant storage.
Since each video channel is a site collection, you can use the REST API to get all sorts of information about the channel including the list of videos.
So this is a channel called "Development" on my Office 365 Video Portal. You can see that there are 3 videos uploaded to this channel:
In order to get the list of videos in a video channel, we need to make a REST call to the SharePoint Search REST API:
_api/search/query?querytext='SiteTitle:"Development" AND ContentTypeId:0x010100F3754F12A9B6490D9622A01FE9D8F01200F9B0E79C5EBC0545B80F5F1B3985E159'&selectproperties='Path,Title,SiteTitle'
The ContentTypeId is the id of the new "Cloud Video" content type and the SiteTitle will be the name of the Channel.
Here is the complete code. I have used JavaScript and the jQuery.ajax function to make calls to the SharePoint REST API. But you can use a variety of other options like the JSOM, CSOM or even the Office 365 APIs. Since all the channels are by default open to users in the tenant, there should not be any major challenges to authentication around this. I haven't tested the code for these APIs myself.
And the logs in my Dev tools console:
