How to decode RSTP stream input

2026-01-21 16:29

Hi,
I'm newbie to the Luckfox Pico board and I have a project that need to receive RSTP as input.
Then, an AI model would perform inference on RSTP stream.
But currently, I do not know how to receive RSTP input?
I found that VDEC library can be used to active decode image hardware, but there is no example how to use it?
Does anyone know how to install VDEC and use it?
Thank for your concerns.

Hello, the RV1103/RV1106 used by Luckfox Pico is an IPC-class chip, which does not have hardware encoding capabilities and accordingly, does not have a VDEC component.

Hello! Can somebody give me an example how to use MPP libarary (Buildroot SDK) to decode rtsp stream or where i can find some rockit examples. Decoding by ffmpeg library has a small fps and large processor load.

i have the same problem. But buildroot sdk has a rk_mpi_vdec.h header, and rockit library reference the decoder capabilities

4.9 VDEC Module
4.9.1 Introduction
The VDEC module provides an MPI interface for hardware operation of driving video decoding and implements
video decoding functionality.

IS it supports only encoder capabilities for VI

The IPC chips of the Rockchip series all share the same Rockit library, and different libraries are packaged according to the chip model. Among them, rk_mpi_vdec.h is not prepared for RV1106.
Whether it has hardware encoding capability needs to be determined from the datasheet. RV1103/RV1106 do not have hardware decoding capability.

What about RK3506? I couldn't find any references to a video decoder.

RK3506 also lacks a hardware encoder, but its software decoding can support up to 1080P@60Hz.
