"About the Rocket M5, I thing it is too big and heavy to put it on the drone (at least the sizes I am dealing with). Of course when you just replace cable with 2 Rockets the latency will not increase dramatically. But If you use some wifi USB dongle…"
"@ChristianL: cool times. I think I usually always use latest possible updates. But what write about the fps could be true. Anyway did you achieve it through wifi or cable. If wifi, can you tell more about your configuration (wifi drivers)?"
"Same for me, tried to compile the 1.3.90 Gstreamer but got stuck. Takes forever on the Pi.
I am currently running on 1.2.4-1, these packages are available in the testing section of the official raspbian repro"
"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…"
"You guys might be interessted of how to decrease Latency to ~110-130ms at least for 720p.
The result is that we now have a set of mode as follows :
2592×1944 1-15fps, video or stills mode, Full sensor full…"
"Hi, This is exactly what I was thinking of doing, I was just not sure if anyone had done it yet!
It is awesome that you have gotten it semi working.
I will install gstreamer on my RPI and test it out. First I will buy an RPI camera this week.
"@Tilman I didn't tested yet 5Ghz yet. But definitely I am going to test it. Currently I am playing with the RasPi setup as AP, so there is no need for additional router in the field, only client NB, or tablet.
C920 I have seen the setup working…"
"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…"
"@Juraj Kolesar Do you run the AirLive adapter on 5ghz? And is there not a problem with the raspberry usb power supply for the C920, I think this camera consumes 240 miliamp but the raspberry only provides something about 150 over each usb…"
"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…"
"Thanks for the answers. I think I am going to try your code.
Anyway did you checked the Logitech C920 cam? It should be working under 100ms latency, because it has its own h264 encoding chip inside. The RasPi than works just for networking and is…"
"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…"
"Have you done any latency tests already? If yes what are the results?
I am playing with similar setup, but I am using APM2.6 instead of DJI.With 720p on RasPi cam and gstreamer I still had about 0,2s latency. On 1080p it was more than 3s. Did you…"
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…
