Re: Go pro fact finding research

Hi all, 

I would also like to add some thoughts on using GoPro.  Well to begin with, I am a huge fan of GoPro cameras, and I was testing GoPro Hero 3+ Black Edition (the latest model) last April.  It would be great if AME purchase new GoPro cameras but maybe it is not the best choice for Brickyard projects.


[Image 1] Six GoPros on a special mount made from a 3D printer.  Didn't really work under Arizona weather.  Photos taken near Tempe.

As far as I remember, ideas of using GoPro cameras started because we wanted to locate cameras outside of the building without any wires connected to the computers.  

GoPro cameras are small, light weight, feature loaded, and are designed to be put under extreme conditions.  However, as they are not built for long-term use,  they have battery issue, overheating issue, and Wifi range issues.  Battery last less than an hour, and if we connect a source of electricity the camera will overheat and turn off once a while.

I also found ways to stream full video into a web browser or VLC media player () and a Mac app controlling and doing low resolution live previews ().  Unfortunately, most of these solutions are for low resolution previews.  Trying GoPro cameras in Max/jitter might still be a very interesting and challenging project, but we can also consider different options.

For example, wifi network cameras can be another good choice.  They are designed specifically for long-term live streaming without being connected to the computer.  Whenever the camera is connected to power source and network, it doesn't even need to be located near the computers.  Image below shows my previous project that used two network cameras in an outdoor environment.

Please let me know your ideas and thoughts.

Much appreciated,
Cooper

Very likely standard httpd would be a bad way to send video since it was designed for sending bytes of characters or a few embedded media objects.   But   Max jit.*  used to read   rtsp video streams as well  ( in the syntax  rtsp://  ?  )

Such long latencies would make GoPro impossible for synchronous action, but we should also think about how to intercalate activity based on durational rhythm, not point-sync’d instantaneous events.

Also, time delaying the feed by 3 hours would be interesting first step to intercalating Montreal and Phoenix

There is a browser object in max. Not sure how it works with video but it sounds like it's worth a shot.

Should have forwarded to the group initially:

Doing some initial research which I will present to the group.  On the Go Pro:

While the wireless feature is designed specifically for controlling and doing low resolution live previews on the Go Pro app, there is a way to stream full video into a web browser via the camera's built in web server.  If any applications that synthesis is using can access this kind of stream (via http://) we should be able to grab video.  A caveat is that the live streamed video has very significant (seems to be > 1 second) lag.  This is likely dependent on resolution, and I would guess 720p video would have less lag than 1080p  - but we'd have to try it to see.

Also, it looks like there is a cable that allows us to both insert an external (3.5mm) microphone AND still utilize the camera's USB port as a power input as to avoid running off the battery.

Here is a video that a youtube user posted covering the video streaming accessibility:  https://www.youtube.com/watch?v=Y1XaBJZ8Xcg
