How do I control the frame rate when I write video using jetson-utils?

I have a numpy queue with a thousand pictures in it.

output = videoOutput("test.mp4", argv=["--frameRate 10"])
for it in img_list:
          cuda_img = cudaFromNumpy(it)
          output.Render(cuda_img)

In theory, the video should be 100s, but in practice it is only 1s, and many of those frames are missing.
I tried to add delay and it worked fine.

output = videoOutput("test.mp4", argv=["--frameRate 10"])
for it in img_list:
          cuda_img = cudaFromNumpy(it)
          output.Render(cuda_img)
          time.sleep(0.1)

Please tell me how to make videoOutput work properly without delay.

Hi,

Please find below for an example:

Please try to setup the framerate in the same manner as the bitrate.
For example:

# output
output = videoOutput(args.output,
                     argv=sys.argv,
                     options={
                        'frameRate': 10,
                        'bitrate': 2500000,
                        'codec': 'h264'
                     })

Thanks.
