TI-EDGE-AI-CLOUD: Edge AI SDK + gsttiovx: edgeai-gst-plugins: tiovxisp: Cannot open 2A config file

Part Number: TI-EDGE-AI-CLOUD

Hi

I am using the TDA4 board running SDK v8.02 along with GStreamer plugins to run the single output pipeline from the tiovxisp page example here (https://github.com/TexasInstruments/edgeai-gst-plugins/wiki/tiovxisp) from the main branch. 

Even though the required files exist, the 2A config file is not loaded and the pipeline does not execute. 

Following is the error generated.

0:00:00.183300300 2368 0x5eda230 ERROR tiovxisp gsttiovxisp.c:886:gst_tiovx_isp_read_2a_config_file:<tiovxisp0:sink_0> Unable to open 2A config file: (null)
0:00:00.183333757 2368 0x5eda230 ERROR tiovxisp gsttiovxisp.c:1078:gst_tiovx_isp_init_module:<tiovxisp0> Unable to read 2a config file
ERROR: from element /GstPipeline:pipeline0/GstTIOVXISP:tiovxisp0: Unable to init TIOVX module
Additional debug info:
../gst-libs/gst/tiovx/gsttiovxmiso.c(1409): gst_tiovx_miso_negotiated_src_caps (): /GstPipeline:pipeline0/GstTIOVXISP:tiovxisp0
ERROR: pipeline doesn't want to preroll.

Any help regarding this is highly appreciated. 

Thanks

    Hello Apeksha. So the issue lies with the naming of the elements. Generally, the tiovxisp plugin expects a sensor name and a sensor ID to be provided along with a "sink_0" prepending to the device and dcc-2a-file parameters. Could you try this command and see if it works?

    gst-launch-1.0 v4l2src device=/dev/video2 ! queue leaky=2 ! video/x-bayer, width=1920, height=1080, format=rggb, framerate=30/1 ! tiovxisp sink_0::device=/dev/v4l-subdev2 sensor-name=SENSOR_SONY_IMX219_RPI dcc-isp-file=/opt/imaging/imx219/dcc_viss.bin sink_0::dcc-2a-file=/opt/imaging/imx219/dcc_2a.bin format-msb=7 ! video/x-raw, format=NV12 ! kmssink sync=false driver-name=tidss

    Hope this helps you!

    Hi Yogesh, 

    Thank you for your response. I am now able to run the modified pipeline and generate an output with the pipeline below. 

    INPUT_FILE="/opt/imaging/imx390/img_0000.raw"
    WIDTH=1920
    HEIGHT=1280
    FORMAT="grbg"
    FORMAT_BPP=2
    FORMAT_MSB=11
    INPUT_FILE_BLOCK_SIZE=$((${WIDTH}*${HEIGHT}*${FORMAT_BPP}))
    DCC_ISP_FILE="/opt/imaging/imx390/dcc_viss.bin"
    DCC_2A_FILE="/opt/imaging/imx390/dcc_2a.bin"
    OUTPUT_FILE="/tmp/output_image1.yuv"

    GST_DEBUG=tiovxsimo:4,tiovxisp:4 gst-launch-1.0 -vvvv filesrc location=$INPUT_FILE blocksize=$INPUT_FILE_BLOCK_SIZE ! video/x-bayer,width=$WIDTH,height=$HEIGHT,format=$FORMAT,framerate=30/1 ! tiovxisp sensor-name=IMX390-UB953_D3 dcc-isp-file=$DCC_ISP_FILE sink_0::dcc-2a-file=$DCC_2A_FILE format-msb=$FORMAT_MSB ! video/x-raw,format=NV12 ! filesink location=$OUTPUT_FILE -e
    But the output image generated is completely dark. I have tried changing the alignment in the raw image to MSB-alignment from LSB-alignment, tried to change to Big Endian image, but no success. 
    Thanks,

    Hello Apeksha,

                Check the setup_cameras.sh file inside /opt/edge_ai_apps/scripts directory. That file is called by the init_script.sh. Inside the setup_cameras.sh, the script is using media-ctl to set the format to 12 bit rggb format. Here, you have specified grbg format. You need to set the format to grbg inside the setup_cameras.sh file and run the init_script.sh file inorder for it to take effect. You can then try and see if it improves.

    Let me know if this was helpful!
