UVC Camera is used supporting MJPG: 1080p@30 / 720p@30 or YUV:1080p@6 / 720p@6.
- HW Setup-i.MX6 Board [HS-O]:
- Video Source (VS-O): UVC Camera connected with i.MX6 Board, USB 2.0 port.
- Video Receive (VR): X86 Laptop
Scenario-MJPG:
- VS-O:
- Capture MJPG stream from UVC for 1080@30
- Send MJPG stream to VR over WiFi (RTP)
- Video Receiver:
- Receive MJPG video stream over WiFi (RTP)
- Decode MJPG (1080@30)
- Display video with 1080p@30.
Current status:
- HS-O:
- Pipeline - 1 : 1080p30 MJPEG Capture, and file dump is working.
- Pipeline - 2 : capture from UVC and stream to X86. Instead of 1080p30, stream is of 1080p6 . 720p30 is working fine though.
Pipeline - 1:
- Transmitter: $ gst-launch-1.0 -e v4l2src device=/dev/video0 num-buffers=1 ! image/jpeg,width=1920,height=1080,framerate=30/1 ! avimux ! filesink location=newtest.avi
- Receiver: used VLC to play newtest.avi on X86. Found it of 1080p30.
Pipeline - 2:
- Transmitter: $ gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw ! jpegenc ! jpegparse ! rtpjpegpay ! udpsink host=192.168.0.103 port=5000
- Receiver: $ gst-launch-1.0 udpsrc port=5000 buffer-size=90000 ! application/x-rtp, encoding-name=JPEG, payload=26, clock-rate=90000 ! rtpjpegdepay ! jpegparse ! queue ! jpegdec ! videoconvert ! fpsdisplaysink sync=false async=false --verbose
Challenge:
- At i.MX6 Board, able to dump MJPG file having 1080@30.
- But while streaming, it always displays at 6FPS or less, so it seems that it is streaming YUV instead of MJPEG.
- While streaming 720p, same pipeline works at 30FPS.
We need your help in review Pipeline – 2 which we are hoping to get us 1080p30 on HS-O setup.
