== Dumping / Streaming ==
=== Requirements ===
* sources (camcorders/DSLRs/webcams/microscopes...)
* frame grabbing (vga?hdmi?composite? Over PCI/PCI-E/USB3?)
* compositing / encoding (OBS? ffmpeg?)
* dumping / streaming
== Grabbing ==
* Analog audio in
* HDMI in
* SD analog video in (Switchable between VGA / S-VIDEO / Composite)
* USB V4L devices (microscopes, webcams)
== Compositing ==
* [https://obsproject.com/ OBS] requires a GPU which supports OpenGL 3.2 or latter
== Encoding ==
* What is a baseline system to do real-time 720p x264
* What is the maximum bitrate we can fill upstream
* Encoder ={Ubiquiti link}=> Upstream relay ==> [[Internet]]
== Dumping ==
* We need some fast local storage
* Low disk space warning ( with temporal estimation of remaining recording capacity )
== Status ==
