Add Streaming Video to any Bio-lab!

Posted by – October 16, 2009

Combining an inexpensive (under $15) USB webcam with free VLC media player software, it is simple to add password-protected internet streaming video for remote users to any lab.  VLC includes the ability to capture from a local webcam, transcode the video data, and stream the video over the web.  It’s available for OS/X, Unix, Linux, and Microsoft systems.

Hint: Video formats are confusing.  Even video professionals have a tricky time figuring out the standards and compatibility issues.  Today’s web browsers also have limitations in what they can display (mime types and such) — which simply means both sides need to use VLC.  Figuring all this out using the VLC documentation takes some work.  Transcoding the video is required and a proper container must be used to encapsulate both video and audio.  Once debugged, it’s good to go.

Here’s how it worked in the lab:

Perl software to control lab syringe pump and valve device, for biology automation, initial version finished today. Works great.  Next, need to add the network code, it can be controlled remotely and in synchronization with other laboratory devices, including the bio-robot.  This software will be used in the microfluidics project.  The software is also part of the larger Perl Robotics project, and a new release will be posted to CPAN next week.
