<![CDATA[Issues Getting voxl-streamer video stream working through RTSP stream on Doodle Labs Helix Radio]]>Good afternoon,

Recently, I've been attempting to configure a setup on the VOXL2 that uses a doodle labs helix radio and a gremsy gimbal.

HDMI from the camera on the gremsy is routed through an HDMI capture card to USB-C on top of the naked 5G expander board. And USB from the doodle is going through USB-2 on the board.

I have been able to successfully get the camera going on voxl-uvc-server and it is outputting frames. I have also been able to view the stream through Ethernet and it looks smooth. It is running on a 640x480 stream at around 1 mbps.

However, when using the doodle radio, the stream will cut out immediately to the point where it is unviewable.

I've tried both decreasing and increasing the bitrate and ran into the same problems. I also tried moving one doodle further away from the other and the stream kept cutting out. However, I can still control the gimbal fine.

Also, here is the output I was getting from voxl-streamer when the stream kept cutting out and not connecting on ATAK:

This "new frame rejected" error would continue on and on, over and over again.

This is on platform 1.0.0
voxl-streamer is version 1.7.1
voxl-uvc-server is version 0.1.3

I was wondering if there are recommended camera settings I should set on voxl-streamer to work with the doodle radio, or if there is insight on the errors voxl-streamer is running into.

Thank you,

John Nomikos.

We can compare to a normal USB camera as well to see if the issue is with specifically streaming from the HDMI to USB capture card

I bet that we can hook up an hdmi camera camera and try to duplicate this on the bench
