Cannot work out image format

[fnoop]

Using seek_viewer with the --output argument, this uses OpenCV VideoWriter (and hence gstreamer) to output the frames through a provided gstreamer pipeline. A pipeline such as this should work (on a raspberry):

OUTPUT="appsrc ! queue ! autovideoconvert ! video/x-raw,format=I420 ! omxh264enc ! h264parse ! rtph264pay config-interval=1 pt=96 ! udpsink host=192.168.1.xxx port=5600 sync=false"

with the client pipeline:

gst-launch-1.0 -v udpsrc port=5600 buffer-size=0 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, payload=(int)96" ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! queue ! avdec_h264 ! autovideosink sync=false

This is pretty standard gstreamer stuff. However for seek_viewer I cannot get it to work - I just get a green box with the odd flapping pixel. I've tried explicitly converting the output frame to RGB but no luck.

Any ideas? This would be a significant improvement as it allows realtime video over wifi such as would be used in search and rescue etc.

Any news here? Im interested in stream the image in realtime via wifi to a smartphone near by.

I would be interested too

Does the v4l2 functionality solve for your usecase?

[crabdancing]

v4l2 solves the streaming concerns. You can stream to v4l2 and then stream from that to wherever via OBS, VLC or whatever else. I could write up a markdown walkthrough if needed! :)

Would be great to have v4l2 support documented in the readme.

Documented, hope that helps.

Thankyou :)
