I’m thinking of using v4l2src of YUY2 output with DeepStream of JetsonNano. The image of pipeline is as below. v4l2src(1920x1080, YUY2) ->capsfilter(for YUY2 input) → converter(format conversion)> nvstreammux > nvinfer(object detection) → nvtiler → nvvidconv → nvosd → nveglglessink The pipeline …

Hello DaneLLL, It is logitech C270 HD Webcam. The following is the information for ‘# v4l2-ctl -d /dev/video0 --list-formats-ext’ from my system. Thank you. ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:…

Hi, Your camera does not support 1920x1080. Please try 640x480. The resolution has to be modified: #define MUXER_OUTPUT_WIDTH 1920 #define MUXER_OUTPUT_HEIGHT 1080 caps_uyvy = gst_caps_new_simple ("video/x-raw", "format", G_TYPE_STRING, "UYVY", "width", G_TYPE_INT, 1920, "height", G_TYPE_IN…

Hi DaneDLL, I followed my pipeline to changed the MUXER_OUTPUT_WIDTH to 640, MUXER_OUTPUT_HEIGHT to 480, same as the width and height in caps_uyvy from your code in #11. It passed build but it still got the same error although my pipeline could work. Thank you.

Hi DaneLLL, I used your code from #11 as it is and compile it on gtx 1080. The compilation failed with giving error as: “deepstream_test1_app.c:249:25: error: ‘transform’ undeclared (first use in this function); did you mean ‘srandom’?” Then i removed all the appearances of ‘transform’ from code…

hi, We have verified the sample on Jetson Nano/DS4.0.1 + E-Con See3CAM-CU135. It shall work if you correctly configure the v4l2 source to meet supported mode in width, height, format, framerate. Suggest you break down the pipeline with fakesink. You may modify C code to run v4l2src device=/dev/vid…

Hello DaneLLL, Thank you for your help. Here is the experiment result for the pipeline test: 1). gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! videoconvert ! nvvideoconvert ! ‘video/x-raw(memory:NVMM),format=NV12’ ! fakesink The termina…

For 5). gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, format=YUY2, width=640, height=480, framerate=30/1 ! videoconvert ! nvvideoconvert ! ‘video/x-raw, format=NV12’ ! nvvideoconvert ! nvdsosd ! nveglglessink –e test result: pop up the black window, no image showed up. The terminal show…

Hi DaneLLL, I modified the code to run the pipeline “v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! videoconvert ! nvvideoconvert ! ‘video/x-raw(memory:NVMM),format=NV12’ ! fakesink”. gst_bin_add_many (GST_BIN (pipeline), source, conv1, nvconv, fsink, NU…

Hi dipeshadekar, For the error: ERROR from element stream-muxer: memory type configured and i/p buffer mismatch ip_surf 0 muxer 3 Please add one line and try again. g_object_set (G_OBJECT (nvconv),"nvbuf-memory-type", 3, NULL); Hi laomao, Not sure why you are not able to launch it. We have Roc…

Hi DaneLLL, My camera worked with deepstream-app -c source1_usb_dec_infer_resnet_int8.txt with 640X480 resolution. I just wonder why it did not work with the code in #11. Thank you for your help.

Hi @Jeff_Bond
You may refer to

And make sure your USB camera can be successfully launched in gst-launch-1.0 first.
