@RichieRich Thanks for the information!
I would test the maximum speed m500 could achieve in a normal condition. So, I will run the mission for this purpose.
By the way, for the motor on m500, I noticed it's the Motor 2216-880KV for 10in props. I also saw there was a 2216-920KV version on Holybro website for s500 frame.
https://shop.holybro.com/spare-parts-s500-v2-kit_p1251.htmlI double check that different the KV rating of a motor will be able to achieve different speeds. In general, the higher KV refers to the faster speed, but the lower in a heavy-lift.
For the defualt 880KV, m500 can achieve 1kg+ payload with up to 10m/s+ speed. So, I am thinking what if replacing 920KV on m500, will it achieve a faster speed? I am wondering do you hava any experiments to test using a higher KV motor before?

@Eric-Katzfey , I am wondering if the aspect ratio is incorrect to get the source video? The 1.77777 is the default one, and I am not sure what is the default aspect ratio on m500?
-
@Eric-Katzfey , I have a look at the /etc/modalai/voxl-streamer.conf.
It seems this config includes a set of different input and output settings. I am wondering if my issue may refer to this config? Do you have a document to introduce the mapping of this config?
E.g., the second line is
"configuration": "tracking". Does it mean the view showing in QGC will be related to the view of the tracking camera?As default, QGC will show which camera's view? If I would prefer to show the Hi-res view, how should I config it?
I also simply try to type in 1.3333 for aspect ratio, but it seems it doesn't work.

@yu-zhang voxl-streamer documentation is located here: https://docs.modalai.com/voxl-streamer/

@Eric-Katzfey Thanks, I double-check the config file, and it seems everything should be good. But there is still no video showing in QGC.
I am wondering if QGC blocks the stream data. I tested both QGC 4.1.4 and the latest 4.2.0 on both my Macbooks (m1 and intel). They all cannot show the video correctly.
I found QGC 4.1.1 got this issue on m1 Macbook, but it should already be fixed in the later versions.
I am wondering what's your QGC version? Do you have a Macbook at hand? If so, could you please make a quick test to check if it's an issue with QGC?

Hi @Eric-Katzfey ,
I tested using VLC on amd64 Macbook, and the streamer works well. It's all the same config as in QGC. So, I assume the latest QGC (4.1.4/4.2.0) still has the issue to fail receive streaming video on host PC.
I will continue to work on my target and hope QGC will cover this issue soon later.
Thanks again!

@yu-zhang Can you please do us a big favor and ask your questions in separate posts instead just adding them all on to a single post? The forum is a resource for all of our customers and having each question in it's own forum posting makes it much easier for other people to benefit from the information in it. And regarding QGC 4.1.4, I use that version for testing but I am on a Linux Ubuntu 20.04 machine so maybe that's the difference.

@Eric-Katzfey Good to know that QGC 4.1.4 can work on Ubuntu.
All right, I will repost my lastest 2 questions in separate posts. Thanks for letting me know that.

Late to the party on this -- but I have been able to build ipk's off of an M1 recently.
I followed: https://docs.modalai.com/install-voxl-docker/
And then also downloaded the image from the developer portal as laid out: https://docs.modalai.com/voxl-cross/
To load:
docker load --input voxl-cross_V1.8.tarTo run:
voxl-docker -i voxl-cross:V1.8Then the docs in all of the Modal repo's work well.
I do have buildkit etc enabled as laid out here: https://medium.com/nerd-for-tech/developing-on-apple-m1-silicon-with-virtual-environments-4f5f0765fd2f but you shouldn't need any of that. Let me know if that helps you. Worked just fine for me -- no special rosetta2 terminal or Docker version.
I'll see if I can contribute something to the docs when I have a moment.

Hi @stevet Late to reply, and thanks so much for your instruction! It's great news for M1 developers like me
I will have a try if it works well, and let you know then.
