There are numerous screen capture applications that will record the computer screen with audio. The one that I use on my Mac is called Smart Screen Capture. It allows you to record only part of the screen and you can choose between the computer mic or the computer audio (browser audio). (Available on the Mac App Store.)

There is JScreenRecorder, that is available under the LGPL, uses Java, and is available from http://SourceForge.NET/projects/jscreenrecorder.

Couldnt it be possible to save the videostream to the sd card on the beaglebone, and then download it afterwards?. i've bought a 16gb sd card hoping that this kind of feature comes :P

One could also allocate some space for loop recording, so you can save in example the last 5minutes continusly, and when you hit a trigger you save that block. i can image users trowing themself on the record button and beein just to late to capture the cool or funny stuff.

This is a great topic- I was just looking at various ways to record video topside and I'd really love to see developers try to tackle that one.  For the ROV I've been piloting in Antarctica (SCINI), we use a bit of custom software that pulls images directly from the address of the IP camera on-board and saves them to a folder on the main hard drive.  It also records telemetry (such as depth, joystick position, voltages, temperatures, etc) in the metadata for each file and has a place for annotations.  

We've been trying to keep all the control software, etc on-board the ROV (so no software is needed on the computer controlling it) but for recording on the computer, this may not be possible. 

I'm sure there is already commonly available software out there that does this sort of thing, but I'm not sure what it would be called.  Ideally we could find something that is already written and is open source, but if not, perhaps someone could write something to do this.  If anyone finds anything that works well, let us know- I know I could use it right away!

Thanks for bringing the topic up, Alexander!

yes the quality is much higher on a gopro, but if you want to explore a shipwreck you want the live video in a high quality so the pilot can see all the sharp edges, not as a standard labtop webcam. if the quality is high in low light that would open up opportunities to get inside the wreck through small holes where divers not are able to get in.

Both good questions!

There've been a few videos. The main reason is that we just got the production Beaglebone capes at the end of December, so people are just starting to get the kits together.

We've primarily used an attached GoPro to record videos. The quality is much higher, and it's really easy to implement.
