TDA4VM: SK-TDA4VM: Issue using tiovxmosaic plugin on gstreamer.

Naveen K

Part Number: TDA4VM

Tool/software:

Hello all,

I am using the tiovxmosaic plugin on gstreamer command to stream either 4 cameras or 2 cameras parallely. Using the below command I can able to stream 4 cameras parallely without fail.

"gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,width=1920, height=1080 ! tiovxldc out-block-width=128 ! "video/x-raw,format=NV12" ! queue ! mosaic.sink_0 v4l2src device=/dev/video3 ! video/x-raw,width=1920, height=1080 ! tiovxldc out-block-width=128 ! "video/x-raw,format=NV12" ! queue ! mosaic.sink_1 v4l2src device=/dev/video4 ! video/x-raw,width=1920, height=1080 ! tiovxldc out-block-width=128 ! "video/x-raw,format=NV12" ! queue ! mosaic.sink_2 v4l2src device=/dev/video5 ! video/x-raw,width=1920, height=1080 ! tiovxldc out-block-width=128 ! "video/x-raw,format=NV12" ! queue ! mosaic.sink_3 tiovxmosaic name=mosaic sink_0::startx="<0>" sink_0::starty="<0>" sink_1::startx="<1920>" sink_1::starty="<0>" sink_2::startx="<0>" sink_2::starty="<1080>" sink_3::startx="<1920>" sink_3::starty="<1080>" ! kmssink sync=false driver-name=tidss -e -v"

my video device for this are /dev/video2 , /dev/video3 , /dev/video4 , /dev/video5.

However if I do the same with my 2 camera setup, I could not see any preview of my camera stream. Below is the command used for this.

"gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,width=1920, height=1080 ! tiovxldc out-block-width=128 ! "video/x-raw,format=NV12" ! queue ! mosaic.sink_0 v4l2src device=/dev/video18 ! video/x-raw,width=1920, height=1080 ! tiovxldc out-block-width=128 ! "video/x-raw,format=NV12" ! queue ! mosaic.sink_1 tiovxmosaic name=mosaic sink_0::startx="<0>" sink_0::starty="<0>" sink_1::startx="<1920>" sink_1::starty="<0>" ! kmssink sync=false driver-name=tidss -e -v"

my video device for this are /dev/video2 , /dev/video18.

I am not sure what is going wrong. I am using the ar0234 sensor with fpd link.

Could someone help with this?

Hi,

Please expect a delay in response due to holiday in US on 27 May 2024.

Hello Naveen,

Which SDK version and which fpdlink fusion board are you using? Are your 4 camera and 2 camera set ups using the same sensors and hardware?

Thank you,

Fabiana

Hello Fabiana,

1. The SDK version I am using is 09_02_00_05.

2. We are not using any fusion board. We are using our own customised hardware setup and connecting it to J24 (CSI2-EXP) connector of this TDA4VM Starter kit.

3. Yes we are using same sensor(ar0234) and hardwares with 4 camera and 2 camera set ups.

Note: For this 2 camera set up, we have tested the above said gstreamer command by adding GST_DEBUG with it to either level 3/4 and at that time I can able to see the parallel streams randomly. But without that GST_DEBUG I couldn't see the stream at any case.

Thanks,

Naveen

Hi Naveen,

Assuming your display is 1920x1080, could you try this:

Keep in mind that the x & y coordinates correspond to the top left of each stream.

Thanks,

Hi Fabiana,
Neither of the above commands worked. I couldn't see stream with those command. But as said earlier I can able to do it if added GST_DEBUG in it.

Thanks,
Naveen

Hi Naveen,

I do not have the AR0234 sensor on hand, so I was unable to test on my end. Try this pipeline instead:

Hi Fabiana,

Even with the above command I couldn't get parallel stream.

Thank you,

Hi Naveen,

Could you share the output of v4l2-ctl --list-devices and media-ctl -p ? Are you seeing any error messages with the failing pipelines?

Thanks,

Fabiana

Hi Naveen,

Could you try using the tiovxmultiscaler element to resize the camera streams and include the widths & heights after the x & y coordinates for both streams like you see the example linked below?

Thank you,

Hi Fabiana,
I have modified the GST command with tiovxmultiscaler element to resize the camera streams and included the widths & heights after the x & y coordinates for both streams and tried, but I couldn't get paralled stream. But as said earlier this same command with tiovxmultiscaler works if I add GST_DEBUG in it.

Thanks,

Hello Naveen,

Could you try having only the two cameras that you plan to use connected to the board and running the two camera pipeline previously shared?

There is a known issue where we see the CSI2RX SHIM DMA context channel 0 accepts all handled data. Due to the driver implementation, all of the other sensors are still streaming so when one (or a subset) of cameras in a multi-camera system is streaming, DMA context 0 accepts frames from different virtual channels.

This issue is being addressed internally but for the time being, streaming from one or a subset of cameras in a multi-camera system is not supported.

Thank you,

Fabiana
