High-resolution (1080x1280) low-latency stream over 2.4GHz Wi-Fi using RKMPP

2026-07-20 9:10

Hi everyone,

I am working on a system setup using Luckfox Pico Mini with an SC3336 camera module and a 2.4 GHz Wi-Fi transceiver. My goal is to stream video at 1080x1280 resolution over 2.4 GHz with the lowest possible latency.

I have a few specific questions for the community:

Hardware H.264/H.265 Encoding (RKMPP): Has anyone successfully streamed 1080x1280 (or ~1.3MP) at 25-30 FPS using the hardware encoder (RKMPP / luckfox_rtsp_mpi) without hitting RAM limits?

Latency & Protocol: To avoid the 2-3s delay mentioned in some RTSP implementations, is UDP/RTP (or GStreamer Pipeline) recommended on Luckfox Pico Mini for real-time streaming? What is the lowest latency (in ms) achieved so far?

Bitrate Tuning for 2.4 GHz: What bitrate (CBR) settings and GOP/Keyframe intervals do you suggest to maintain a stable stream through walls on 2.4 GHz Wi-Fi?

Any code snippets, GStreamer pipelines, or SDK configuration tips would be greatly appreciated!

RV1106 does not support RKMPP development, and Rockchip has not provided standard interfaces for it. However, the rkmpi library can still achieve hardware-accelerated encoding. For GStreamer based on rkmpi, you can refer to the community-developed version at: https://github.com/nbfalcon/gstreamer-rockchip-rv1106. Specific latency and bitrate settings need to be considered based on actual conditions.
