Thanks for your response.
Originally I thought I would transmit video directly with gstreamer to
I've been following
and so far I've had mixed luck. I think you're right the WLAN is not
good enough for doing this reliably.
So now I'm going to try and ease the workflow by having each laptop
transmit asynchroniously what they record
The idea is to save locally and not have to go laptop by laptop
recovering video material.
So I'm going to try and suggest to use File Share Activity:
I'm still trying to get the server component to fetch all files.
I will probably patch the activity to be able to share all video journal
We will use record unless we can come up with a clever gst-launch line
that will record in hi-res to USB,
and a way to share those files as well.
It will be the children who record so the user experience must be pretty
simple and friendly.
Our working document for the project is:
the event will document the experience in native communities in Lima and
the highlands of Puno:
Thanks for your suggestions
I cc other in the team to keep them on the loop.
