Hello @SKA,

Thank you for the details. I can't think of anything right now, but will double check this.

I know that there is one potential issue in voxl-camera-server - the SPS header (which is part of the H264 / H265 stream) is only sent by the video encoder once (at the beginning of the stream). I believe that voxl-streamer will cache the SPS packet (which contains things like resolution, etc) and i think when clients connect to voxl-streamer, then it will send that SPS header to the clients. However, if voxl-streamer does not get that first header, it will not be able to forward it to the clients. This is a guess for now, but could be related to the issue that you are seeing.

I can look into this issue. Can you please let me know how exactly to set up VLC for 0ms cache? I want to make sure that my test is the same. Also, which version of VLC are you using?

Also, i noticed one thing - you are using hires_misp_color stream from camera server, which is not actually encoded, but YUV. Then voxl-streamer will take those YUVs and encode them (using hardware encoder). Is there a reason why you are not using the hires_misp_encoded stream to get H264 directly from camera server and serve it using voxl-streamer without re-encoding? I wonder if in the old SDK you were using _color or _encoded stream?

@Alex-Kushleyev Ok, I will order it in the future.

@jeremyrbrown5 We have figured it out. It was the parameters SYS_HAS_MAG and SYS_HAS_GPS. Will be testing autonomous flight tomorrow!

Hey guys, do you think my board is damaged.

Hello @newdroneflyer ,

In order to adjust focus of the hires camera, you need to do the following:

loosen the screw that holds the lens and prevents it from turning. this will allow the lens to turn within the assembly turn the lens using the lens focus tool (should have come with your Starling 2), it is a black plastic tool that goes around the rim of the lens and allows you to turn the lens. after focusing, tighten the screw that was loosened in step 1.

Here is the picture of the focus tool, it has two sizes - one for hires camera, one for tracking camera (if needed). You should have received one with the Starling2 (in an envelope, probably different packaging).

@Piyush-Singh, please double check that you have the imx214 sensormodule bin for slot 0 in /usr/lib/camera/ (since you have M0084 connected to J6 and the IMX214 camera connected to the "lower" port (JL) of M0084, so the resulting connection of the IMX214 camera will be mapped to VOXL2's J6L (slot 0)).

You can find all the sensormodule files in /usr/share/modalai/chi-cdk/

Hi @JoonaR,

Yes, the Starling 2 drones are shipped with the lepton adapter (M0187), but Lepton sensor itself is not included.
