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?

@Sarika-Sharma and I also wanna tell you my goal i.e. stable indoor flight without GPS

@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.

@cbay ,

As long as the Boson / Boson+ 640 (or 320) supports MIPI output, it should work. We believe that some Boson models do NOT have MIPI support (HW limitation) but all Boson+ do have MIPI support. Please check with your vendor to make sure MIPI output is supported.

Also, did you actually mean M0187, or something else? M0187 is an adapter for a Flir Lepton : https://docs.modalai.com/M0187/
