"Nice one, Christian!
I've been flat out with a big product launch, unfortunately, and just have had no spare brainpower left over. Getting to the end of that though, happily. I've gotta package up the new version of GStreamer (or wait around and…"
"Some more work done this weekend - I've got it to the point where it's building and running with the custom EGL display context. Just need to write the rendering code in egl_telemetry_renderer.c and find a way to split the display into left and…"
"Interesting! No, I haven't looked at the C920, but that sounds like an interesting candidate for stereo video (as the RPi only has the headers for a single CSI camera, sadly). Have you tried it and actually achieved sub-100ms latency over network?…"
"I've measured 150-180ms latency, @Juraj - that's 720p RasPi to RasPi. 1080p I found has some serious framerate problems right now - seems like a bug in the receive module, but I've not looked into it as 720p's fully sufficient for the Oculus Rift…"
"Nice idea, @Tilman! I'll definitely be keeping an eye on things!
Cheers @Jonek! Here's hoping - I could sure use the help =)
The video is sent over RTP (all using a GStreamer pipeline). Telemetry is sent over a custom protocol over UDP.
"Not with Gstreamer it won't - I've tried it and it's way sluggish at any decent frame size. But it'll do it in hardware quite happily, hence the EGL stuff. Still, if you can think of any more convenient means to render an overlay, I'm all ears! The…"
Inspired and informed by the Raspberry Pi-based FPV project started by Philip, I'm putting together some software that will run a RasPi FPV rig, complete with an OSD based on data pulled from a Naza GPS module tap and an MCP3008 analog to digital…
"Frustratingly, not yet - I've been flat out in software development land for my company and haven't had any spare brainpower to devote to it. I'm hoping this week is gonna change that, as I'm coming to the end of a big bout of stuff.
The TX side is…"
"Indeed, @dronebriz - I'll definitely be porting that. I'm currently working on the OSD component, as it turns out Gstreamer's Cairo elements simply don't work right on the Pi because they do everything on the CPU, and the Pi's too slow to cope. I'm…"
"Still in development, @Aytek, but going well! I plan to open source the result. It's going to use an MCP3008 ADC chip (wired to the GPIO pins) in conjunction with a voltage/current sensor, and a tap on the NAZA GPS module to pull out location &…"
"Speaking of power... How are people powering the Ubiquity Rocket M-#?
I've not messed with Power Over Ethernet before. I'm wondering about grabbing an RJ45 crimping tool and making my own short Ethernet cable with the appropriate (?) lines hooked up…"
