Hi guys, I have a usb camera with YUYV and H.264 output format, and I try to use nvv4l2decoder to decode it and display, but it has obvious delay and lag. My gst pipeline:
gst-launch-1.0 -vvv v4l2src device=/dev/video2 io-mode=4 ! video/x-h264,width=640,height=480,framerate=30/1 ! nvv4l2decoder ! "video/x-raw(memory:NVMM), format=(string)NV12" ! nv3dsink sync=false
I’ve searched the forums, but still haven’t figured out why, and I try to some solutions like add
io-mode=2 or 4 for
v4l2src and some other parameters for
nvv4l2decoder, but all of these didn’t work. Since omxh264decoder has been removed from L4T R34, so I didn’t test CPU decoding on Jetson, but I have tested on my local x86 PC, it works very well with avdec_h264.
Any suggestions are welcome.
