I’m trying to record video and save it as a file from my camera. I’ve attached a cpp file from the manufactuerr of the camera. The pipeline works, but it doesn’t do anything when ‘r’ is pressed. Can someone guide me on how to record on the jetson?
videocapture_camera.cpp (2.7 KB)
hello aranis.das,
it’s basically gst pipeline. please try follow to record the video stream with h264.
$ gst-launch-1.0 nvarguscamerasrc sensor-id=0 num-buffers=300 ! 'video/x-raw(memory:NVMM), width=1280, height=720, framerate=30/1' ! nvtee ! omxh264enc bitrate=20000000 ! qtmux ! filesink location=video.mp4

Thank you for the response Jerry
I saw the output and every recording seemed the same. I tried to change the pipeline to the maximum of the sensor ( Resolution: 3280 × 2464 (per camera)) but it looked very similar to the 1080p one.
Also, GST_ARGUS showed 1280 x 720, does that mean anything ? :
gst-launch-1.0 nvarguscamerasrc sensor-id=0 num-buffers=1800 ! ‘video/x-raw(memory:NVMM), width=3280, height=2464, framerate=20/1’ ! nvtee ! omxh264enc bitrate=20000000 ! qtmux ! filesink location=video.mp4

Another thing, the num-buffers parameter specifies the length of the recording, but for some reason it goes over (I set it for 1800 (1 minute) and it recorded 1:30)
hello aranis.das,
did you meant the recorded video always present the 1st frame?
if yes, please examine the output frame-rate, otherwise this is more like the issue on sensor side.
the num-buffers parameter specifies the number of frames it’ll captured.
1:30 should be correct since it’s a 20-fps configuration, i.e. 1800/ 20 = 90 sec.

I see. No, but the quality seems to less than 3280 × 2464. Is there a way to maximize quality? I know the resolution was specified in the pipeline, but I’d like to know if theres a way to force it to show max resolution. I am looking for lower fps, higher quality frames for my application.
Also, is it possible to save video from both sensors at the same time (synchronized)? The C++ code I provided did do that, but it didn’t work past 480p.
hello aranis.das,
it depends-on your encode settings, usually due to the bitrate config.
please refer to Encode Examples to revise the pipeline for testing with your use-case.
are these two cameras have hardware FSYNC pin connected?
you may refer to Topic 1070823 for reference, it shows the approaches for dual camera frame synchronization in software level.

Thanks for the response. Do you think there’s a better way to record video? I am working on a stereo vision setup, but its not in realtime. So highest resolution with an fps of atleast 5 is what i’m looking for. Is there a more effective way to get input?
what did you meant a better way?
it depends-on your sources content. video record is simply sending the camera stream to encoder and writing into memory.
In terms of quality. I think this will do for my application. Thanks for the help
