Missing GStreamer RGA Plugin (rgaconvert) on OPi 5 Plus (Ubuntu 24.04) : Feature Request

[AdityaKumar4]

Feature Description

I am setting up an HDMI Input streaming pipeline on the Orange Pi 5 Plus using the latest Ubuntu 24.04 LTS image. While the hardware encoder (mpph265enc) is present and working, the GStreamer RGA plugin (usually rgaconvert or gstrga) appears to be missing.

This plugin is critical for converting the high-quality HDMI input signal (NV24/BGR) to the format required by the hardware encoder (NV12) without overloading the CPU.

Hardware & OS:

• Board: Orange Pi 5 Plus (RK3588)
• OS: Ubuntu 24.04 LTS (Noble Numbat) - Joshua Riek Image
• Kernel: 6.1.0-1025-rockchip (verified via uname -r)

Steps to Reproduce:

1. Install the full multimedia stack:

sudo apt install gstreamer1.0-rockchip1 librockchip-mpp1 librga2 librga-dev

2. Check for RGA plugins in GStreamer:

gst-inspect-1.0 | grep -i "rga\|convert"

Expected Behavior:
I expect to see rgaconvert, gstrga, or mppvideoconvert listed, allowing for hardware-accelerated color space conversion.

Actual Behavior:
Only software converters (like videoconvert, audioconvert) and the MPP Encoders/Decoders (mpph265enc, etc.) are listed. The hardware accelerator for conversion is missing from GStreamer, forcing the use of the CPU-intensive videoconvert.

Context

• dmesg | grep rga confirms the RGA hardware is initialized (rga3_core0, rga2).
• librga.so is present in /usr/lib/aarch64-linux-gnu/.
• The missing piece seems to be the GStreamer wrapper (libstrga.so).

Impact
Without rgaconvert, capturing HDMI Input (which defaults to NV24/YCbCr 4:4:4) and encoding it to H.265 (which requires NV12) forces a software conversion. This limits performance to ~10-15 FPS on 1080p streams, whereas hardware RGA conversion would allow 60 FPS.

Question
Is there a specific package or PPA I need to enable to get the rgaconvert plugin on Ubuntu 24.04? Or is this plugin currently not packaged for Noble?

Thank you for your hard work on this project!

gstreamer-rgaconvert
can you try this?
It sounds like you are working on a video processing or graphics task on the Orange Pi 5 Plus and hitting a roadblock with the Rockchip Hardware Acceleration (RGA) tools.

Here is the translation of your message into English:

"I am facing the same problem as you. I have tried many images, such as:

Orangepi5plus_1.2.0_debian_bookworm_desktop_xfce_linux5.10.160.img

Orangepi5plus_1.2.0_debian_bookworm_server_linux5.10.160.img

Orangepi5plus_1.2.0_ubuntu_jammy_server_linux5.10.160.img

None of these images include rgaconvert. I am wondering if it is possible to write a plugin myself."
