Dear Support Team, **• Hardware Platform (NVIDIA ORIN NX)** **• DeepStream 7.0** Dear Support Team, I hope this message finds you well. I am encountering an issue while attempting to crop a frame from a video stream in my DeepStream 7.0 application, running on a NVIDIA Jetson Orin NX wi…

Hi @abdul.m When you crop using the VIC there is a limitation on the min output resolution. The output must be at leas 1/16 of the input resolution. For 1920x1080 the min output resolution would be 120x68. You can either adjust your output resolution to continue using the accelerated cropping or c…

But i want to use opencv in my cpp code , i want to do another method also i want to resize the cropped frame and overlay the exact frame with red box around resized cropped part…

I think there’s an optimized way to achieve this using nvcompositor for cropping and overlaying, and nvdsosd for adding the red box. However, you will still encounter the resolution limitation I mentioned earlier because nvcompositor relies on the VIC. We have used OpenCV with CUDA acceleration ove…

If you just want to cropping and saving a specific area, you can try to refer to our deepstream\sources\apps\sample_apps\deepstream-image-meta-test sample. You can try to add a bbox coordinate to the metadata and use the nvds_obj_enc_process to save that to the jpg directly.

But i want to use opencv in my cpp code , i want to do another method also i want to resize the cropped frame by using bicubic interpolation and overlay the exact frame with red box around resized cropped part…

i am using only one input video that video format is h264, but i am using Nvstreamux in pipeline

OK. So why do you need this conditional statement in your code? if (step < width * 3) { g_print("Invalid step size: %d. Skipping frame...\n", step); free(src_data); // Free allocated memory continue; } You just added a nvvideoconvert in your code, but you did not specify a filter for…

can you help me, now i am looking for to save each frame in live streaming using cv:: imwrite but i am getting noise frame like this , If i can solve this issue, i can solve rest of things. [frame] this is the code i am used : #define MUXER_OUTPUT_WIDTH 1280 #define MUXER_OUTPUT_HEIGHT 720 #defi…

Can you try adding an nvvidconv and capsfilter after nvdsosd and moving the prove to that nvvidconv? ... ! nvdsosd ! nvvidconv ! capsfilter caps="video/x-raw" ! ... ^------------- probe here That will copy the NVMM memory to the CPU regular memory and remove batching, sim…

My code is worked, but my output is not clear here i attaching my output and code [frame] static GstPadProbeReturn nvvidconv_src_pad_buffer_probe(GstPad *pad, GstPadProbeInfo *info, gpointer u_data) { // Access the buffer from the probe info GstBuffer *buf = GST_PAD_PROBE_INFO_BUFFER(info…

This pointer does not point to the raw image data. You can refer to our Dump NV12 NvBufSurface into a YUV file to learn how to get the raw image data from the NvbufSurface.
