I am trying to record videos from a connected camera. I am trying to use a python script but alternative method is fine if someone has a suggestion. With script, which works on other PCs does not work on the Xavier. I get an output video of only a few Mbs and the video is only the first frame. I hav…

You may try: gst_out = "appsrc ! queue ! videoconvert ! video/x-raw,format=BGRx ! nvvidconv ! nvv4l2h264enc ! video/x-h264,format=byte-stream ! h264parse ! matroskamux ! filesink location=test-nvh264-writer.mkv " out = cv2.VideoWriter(gst_out, cv2.CAP_GSTREAMER, 0, float(cap.get(cv2.CAP_PROP_FPS)),…

Glad to see it worked out. The second term signal may not be be relevant for your case (it is sometimes required for terminating a pipeline with EOS and nvarguscamerasrc). You would just change the VideoCapture from V4L VideoCapture(0) to the gstreamer pipeline capture. Then I would expect the fra…

recordVideo.py (958 Bytes) Attached is what I attempted based on what I think you are suggesting, but I still get a failed to open output error msg.

I added the following after the CAP to see what it was returning: w = cap.get(cv2.CAP_PROP_FRAME_WIDTH) h = cap.get(cv2.CAP_PROP_FRAME_HEIGHT) fps = cap.get(cv2.CAP_PROP_FPS) print('Src opened, %dx%d @ %d fps' % (w, h, fps)) The result is: Src opened, 0x0 @ 0 fps so it doesn’t look like it is ope…

Seems the capture pipeline failed to start. You would try this customization of your code: import cv2 # Get information about your opencv build options print(cv2.getBuildInformation()) # Open camera cap = cv2.VideoCapture("v4l2src device=/dev/video0 ! video/x-raw,format=YUY2,width=1920,height=10…

I am on it. I will report back results. Thank you so much for the support these past few days.

Ok, So recompiled CV2 with Gstreamer. I now get this with build information: Video I/O: DC1394: NO FFMPEG: YES avcodec: YES (ver 57.107.100) avformat: YES (ver 57.83.100) avutil: …

Ok, so this seems to be the winner: cap = cv2.VideoCapture("v4l2src device=/dev/video0 ! video/x-raw,width=1920,height=1080,format=YUY2,framerate=30/1 ! videoconvert ! video/x-raw,format=BGR ! appsink drop=1", cv2.CAP_GSTREAMER) This now opens the stream and records the video. This is the same as…

It may be an issue with player, I don’t see that. From the test_h264.mkv file recorded from gstreamer, what gives: # I see framerate=30/1 from this gst-launch-1.0 filesrc location= ./test_h264.mkv ! matroskademux ! h264parse ! fakesink -v # I see a solid 30 fps when decoding on Jetson, even setti…

is the problem. You may rebuild and reinstall opencv using one of these scripts.
