Dear all,
I used USB 3.0 ports of Tx1 board to get FullHD@30fps from Hitachi camera via Twiga board, base on OpenCV 3.2.
Can you help me to accelerate frame rate of camera?

Thanks a lot.

Hi Steve, how does it behave with gstreamer?

I also tried to do use GStreamer to get video and HVEC compress, but i met some problem as following:

  1. Delay time is higher 5s (second)
  2. Loss packet, picture breakup.

Note: It’s good at low resolution (VGA or smaller), but very bad at bigger resolution (as HD or FullHD).

Do you have any guideline to use gstreamer with Tx1 or sample code?

Please try
gst-launch-1.0 v4l2src device=/dev/video1 ! ‘video/x-raw, width=640, height=480, format=(string)I420’ ! nvvidconv ! nvoverlaysink
