I need to develop a video streaming server which would stream a live video to multiple users. It needs to support the following "video" sources for the re-stream server:
- web-camera
- surveillance camera (already supports MJPG stream)
- scanner
I understand that I would need a different driver for adding support to each video input device.
I also need to support the video-display in:
- web-browsers
- Mozilla Firefox 3.6
- Internet Explorer 8
- desktop applications developed in C++ / QT 4.6
My questions:
- What would be a good video output format that can be used to support the required browsers/applications?
- Is there a similar Open-Source, Commercial, etc. solution which I could use to make my work easier and faster?
Unfortunately there is no good consensus on one format for streaming. I would investigate multi-stream (http streaming, RTP streaming, etc) solutions so you can support multiple clients (Firefox, IE, iOS Safari, Android, etc).
A couple of good streaming servers products are:
- Kaltura (open source and commercial)
- Wowza Media Server (commercial w/ free trial)
There are tons of other good options out there too.
I managed to complete the video re-streaming server and I've used the following:
- MJPG format for video stream, as it is basically a standard which is natively supported in modern browsers, except in IE, but there are free ActiveX controls, allowing IE to properly display MJPG streams.
- Solutions, libraries:
- For the Web Camera I've used the TVideoGrabber from Datastead Software, it is a commercial solution, but it works great, and it can be used with a lot of environments (Visual Studio, Delphi, C++Builder).
- For the Scanner, I used WIA 2.0 library.
- Security Camera already supported MJPG, so I basically forwarded the stream from the camera as my server's output.
