Shortly after the announcement of the first release of the WebRTC extension for the UV4L Streaming Server, here's another update! As promised, Audio from an input device (i.e. microphone) can now be optionally added to the live stream!
A pure HTML5 test page is here.
At the moment audio must be enabled via a command line option passed to the Streaming Server plug-in (see the documentation).
Video & Audio streams have been successfully tested on Chrome, Opera and Android. For some reasons, when audio is enabled, Firefox does not display the Video stream. The problem is under investigation, but if you know the reason, please give some hints.
Yes, it's true! The native WebRTC extension for the UV4L Streaming Server is now ready!
At the moment, this extension is available for Raspberry Pi 2 only. Packages for x86 will be provided soon. The Raspberry Pi 1 will not be supported. Again, do NOT install the WebRTC extension on the Rasperry Pi 1.
To know how to install UV4L and the WebRTC extension please refer to the appropriate documentation section. Here are the instructions for Raspbian.
Support for audio is work-in-progress. Among the nice things which are now possible there are NAT traversal, VP8 encoding, efficient adaptive streaming, echo cancellation, encryption, very short delays, etc...
Once installed, to quickly try it, go to the Streaming Server page, navigate to the WebRTC Page and press "Start" to get a live stream. You can take the source of that HTML5 page and modify/use it as you prefer.
Tested on recent versions of Firefox, Chrome, Opera, Android. Safari does not seem to support WebRTC (deliberately).
A first screenshot (~200ms delay example) is here.
New, improved releases of the raspicam driver and streaming server are out.
New features include:
- support for multiple clients in the Streaming Server
- new --intra-refresh-mode H264 option
Please check the appropriate material under the Documentation section for manuals or informations on how to install the software.
These are the features on which there is some work-in-progress at the moment:
- Support for multiple (simultaneous) clients in the Streaming Server
- Record while streaming option
- HLS (MPEG-TS) in the Streaming Server
A new release of the raspicam driver is out. It fixes one bug about JPEG Still Captures resulting in unexpected resolutions. Please upgrade.
