I need to improve the quality of videos encoded on Jetson Nano captured from A USB 3 camera. I want the highest possible quality that the Nano can give.
This the pipeline I am currently using

gst-launch-1.0 -e v4l2src device=/dev/video0  ! 'video/x-raw, width=(int)3840, height=(int)1080, framerate=(fraction)30/1' ! queue ! nvvidconv ! nvv4l2h264enc maxperf-enable=1 bitrate=16000000 ! h264parse ! mux. pulsesrc ! audio/x-raw,rate=48000,channels=2 ! queue ! audioconvert ! queue ! opusenc bitrate=512000 ! mpegtsmux name=mux ! filesink location="jaH264.mp4"

I can tell that the video quality is inferior to when I record using the same camera on a windows machine. Moreover the video is not playble on Iphone.

What is the best gstreamer pipeline that will give me the best quality video which is also playble on Iphone?

Thanks

You may try main or high H264 profile (nvv4l2h264enc property profile=2 or =4).

Thanks @Honey_Patouceul but no improvement in the quality, also still not playable on Iphone.

Hi,
Please try to set CBR + virtual buffer size:
