Vdocipher video in asp.net: aspx and aspx.cs files:
Do not save API Secret in the code
API secret is a key which gives your website authority to generate access tokens (OTPs) for video playback. This secret key can also be used to upload, delete videos in your vdocipher account. Hence, it should not be hard-coded in the application. It should be kept as an app secret. In the above example, it has been added to the web.config file which is not the recommended method. Please read this official article on best practices of saving secret keys in ASP.NET.
Download the complete sample application from the Github.
Adding watermark to the videos
Watermark can be added when generating the OTP in the controller file. Please read this article on structuring your watermark and a sample code. The watermark has to be URLencoded and sent as a post data. You shall need to change around line 33 to send annotation information. Let us know if you find any trouble with the watermark setup.
A note about caching
OTP generated here is temporary. You can not cache this OTP and send it to multiple users as it might cause trouble. The OTP once used gets expired and can no longer be used to play video. Some extensions might try to automate the page rendering and especially when on pages which do not need login. The configuration must be set to make sure pages with embedded videos are not cached and cause error while playback.
For reference about how everything works, please check API reference.
