    Hello, I am attempting to stream encoded video over a somewhat long range radio link (imx412 @ 1024x768 on the pipe hires_small_encoded).

    Voxl portal:

    • acceptable latency & performance over ethernet
    • buffers and jams up when streaming over radio link

    RTSP stream through vlc:

    • extremely high latency (1-1.5s) over ethernet
    • works over radio link, but with same latency issues

    As far as I can tell, the encoded stream should be within 2Mbps which is well within the capability of our radios, especially at the range I've been testing, so I'm not sure why voxl-portal buffers and locks up while voxl-streamer doesn't.

    Not sure if I read all of this forum page correctly, but it seems like I should not be experiencing latency nearly this bad using voxl-streamer: https://docs.modalai.com/camera-video/low-latency-video-streaming/

    Let me know if I am doing anything obviously wrong. Thanks!
