Yes this was released around late fall of 2020 and was sent out in emails to existing customers and we added it to our docs.
But @Ashneel_Reddy, please know that while Wowza Streaming Cloud allows you to stream .mp3 and H.264-encoded .mp4 and .flv files, these files must be hosted on a web server, Google Storage, or Amazon S3 bucket. There is no direct upload of say your own personal mp4 file. Also, it’s only one file at a time.
Keep in mind another new feature in Cloud in 2020 was Live to VOD.
In Streaming Cloud, you can create a VOD link from your livestream. This was announced in May in emails, blogs, videos and here in the forums.
