RGA2 Error on rk3568 When Handling Memory Larger Than 4G! #22

Closed shivabohemian closed 5 months ago

shivabohemian commented 5 months ago

On the rk3568 platform, the RGA2 is reporting an error when handling memory larger than 4G. Is there a need to modify the gstreamer-rockchip or mpp code to address this issue? Thank you! rga driver version：RGA multicore Device Driver: v1.2.25 rga API version：rgaapi version 1.10.0[5]

Hi,

This is just a mirror repo, please report this issue to the RGA maintainer(or commiter).

Sorry, I only found the official gstreamer-rockchip repository here. I am using this repo's latest gstreamer-rockchip plugin for transcoding, but the screen turns all green. Do you possibly know the reason for this? The old gstreamer-rockchip in the SDK doesn't have this problem. Below is roughly the video transcoding part of the gst. mppvideodec format=23 ! mpph265enc rc-mode=vbr width=1280 height=720 ! h265parse

please contact rga developers for this issue.

according to the log, you are using a device with ddr larger than 4g, and the rga might not be able to handle it.

it's a common issue, they should have a document about how to workaround it. maybe limit the total memory to 4g or limit the video memory to 4g(drm allocator or dma heap allocator). anyway, i don't know much about it, just providing what i've heard from other customers.

Thank you for your answer. By the way, the mirror repository's gstreamer-rockchip can be compiled and used directly, right?

JeffyCN commented 5 months ago

right, use meson or dpkg-buildpackage

When I compiled the latest gstreamer-rockchip code, I found two problems: the first is the plugin without mppvp8enc, and the second is the green screen after transcoding now. What's going on here? My gst command (below) is normal in very old gstreamer-rockchip. mppvideodec format=23 ! mpph265enc rc-mode=vbr width=1280 height=720 ! h265parse

1/ enc plugins would only be registered when mpp can init it. so if vp8enc is missing, please ask mpp maintainer. https://github.com/JeffyCN/mirrors/blob/gstreamer-rockchip/gst%2Frockchipmpp%2Fgstmppvp8enc.c#L315 if (!gst_mpp_enc_supported (MPP_VIDEO_CodingVP8))

2/ please contact rga developers for rga issue.

Ok, thank you very much!
