Record Video in 60fps

itaigolan — Thu, 18 Apr 2024 01:42:38 GMT

I'm using an imx8mp on a variscite dart board and a basler camera. I'm trying to record a video in 60fps and I tried this command from the Linux users guide:

gst-launch-1.0 v4l2src device=/dev/video2 num-buffers=300 ! video/x-raw,width=1920,height=1080,framerate=60/1 ! queue ! vpuenc_h264 ! h264parse ! mp4mux ! filesink location=output.mp4

This command seems to record the video in 15fps instead of 60 despite the camera showing the video in 60 fps. Does anyone know how I can increase the framerate of the recording?
