Problem recording depth and color videos

[meligranda]

Hi,
I need to get the colored depth video and the color video separately in mp4 format and for that I was using the functions get_color_image() and get_colored_depth_image() and then videowriter of opencv, but the amount of frames that I get with the functions does not correspond to the configuration that I choose for the camera. I tried also saving all the frames with imwrite and then generating the video with ffmpeg, but again I get far fewer frames than I should be getting.

Does anyone know why this is happening or how can I fix it?

Thanks!
