Gstreamer issue in RZ/G2L

mahesh 4 months ago

Dear Renesas Team,

We are using Renesas RZ/G2L smarc-evaluation board and the bsp/vlp version is 3.0.1, in which we have enabled all the dependency of g-streamer and trying to stream an IP-camera, while running the g-streamer command and accessing the ip-camera(rtsp stream) we are facing the below issue,

root@smarc-rzg2l:~# gst-launch-1.0 -e rtspsrc protocols=tcp location="rtsp://admin:Smet1234@192.168.1.216:554/cam/realmonitor?channel=1&subtype=1" ! queue ! rtph264depay ! h264parse ! queue ! omxh264dec !

Hi Mahesh,

> MMNGR: open error.
> ...
> MMI open: No such file or directory

This is the reason of you issue. This error means MMNGR was missing in your environment.
If you build BSP/VLP 3.0.1 correctly *with codec feature package*, MMNGR will be available at boot. And you can see it when run:
# dmesg | grep -i mmngr
# lsmod | grep mmngr

If you do not see MMNGR in above commands, you have build the system incorrectly.

Hi Mahesh,

Your result means MMNGR already available. You can rerun GStreamer command.

If you still have same error "MMNGR: open error.", check whether /dev/rgnmm exists or not.
This is a device driver made by MMNGR. If MMNGR is available but this device driver does not exist, some errors must have occured in MMNGR (in that case, check all messages in dmesg for clue).

I guess you had changed somethings in the devicetree, regarding CMA memory reserve?

Hi HungT,

As per your instructions we have changed the cma allocation in .dts file for camera streaming, please find the below memory configuration file.

reserved-memory {

#address-cells = <2>;

#size-cells = <2>;

ranges;

global_cma: linux,cma@58000000 {

compatible = "shared-dma-pool";

linux,cma-default;

reusable;

// reg = <0x0 0x58000000 0x0 0x10000000>;

reg = <0x0 0x58000000 0x0 0x20000000>;

};

mmp_reserved: linux,multimedia {

compatible = "shared-dma-pool";

reusable;

// reg = <0x00000000 0x68000000 0x0 0x8000000>;

reg = <0x00000000 0x78000000 0x0 0x10000000>;

};

};

Please let us know what changes do we have to do.

Thanks & Reagards
