从DVR输入到wowza，然后从wowza输出到Web应用程序

Question

I have a set of cameras connected to a DVR which stores the streams from the camera. I was wondering if it is possible to to configure WOWZA to be able to pull videos from the DVR(a different machine than the one WOWZA is hosted on) and then stream them back to a web application.

This is the acrhitecture:

It is also important for me to mention that in the web application I need to have the following abilities(which means WOWZA will have to support them):

• Simple play/pause functionality
• Resume if pause was pressed
• Ability for seek (AKA jump to time)
• FastForward – meaning playing the video in different speeds(in addition to the regular X1 speed)

Is it possible to implement something like that and how?

Answer 1

You didn't mention file format. Wowza does not transcode and perhaps your DVR files are not in a format suited to live streaming.

Sorenson Squeeze has the ability to watch a folder for new files that appear, transcode them, optionally move them to another folder (even across the network), and then have those videos published via your web server.

If you add Wowza and configure it to point to the output folder of Sorenson Squeeze, then you can stream the video via your web server. Once the video is streaming, all the 4 features you mentioned (ie- play/pause, resume, seek and adjust play speed) are available.
