I used the v4l2tools to encode the MJPEG video from /dev/video1 to h264 and output it to /dev/video2 with the command:
sudo ./v4l2tools/v4l2compress_omx /dev/video1 /dev/video2 and usind ffplay /dev/video2 i get the following stream with some green stripe:
When I tried to use rpos to stream with rstp option 3 from /dev/video2 I got nothing in the onvif device manager.
Any ideas or suggestions to get this stream working with onvif device manager?
Hello, I tested this project with a raspberry pi 3 and a raspicam v1 and it worked great. Right now I trying to use RPOS to stream via ONVIF a virtual video created with V4L2 Loopback.
With Python + OpenCV + V4L2 I dump the MJPEG video to /dev/video1 and with RPOS using the usbcam config. rpos USBCAM config: { "NetworkAdapters" : ["awdl0","eth0", "wlan0", "en0"], "IpAddress" : "192.168.0.10", "ServicePort" : 8081, "Username" : "admin", "Password" : "admin", "CameraType" : "usbcam", "CameraDevice" : "/dev/video1", "RTSPAddress" : "", "//":"Normally left blank.

When I run
node rpos.jsI get no errors and the following output:Then I tried to get the stream via ONVIF with iSpy software, but the stream is blank.
Troubleshooting:
ffmpeg -f v4l2 -list_formats all -i /dev/video1to check if the MJPEG stream is ok I get the following output: ffmpeg version 4.1.6-1~deb10u1+rpt1 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 8 (Raspbian 8.3.0-6+rpi1) ... libavutil 56. 22.100 / 56. 22.100 libavcodec 58. 35.100 / 58. 35.100 libavformat 58. 20.100 / 58. 20.100 libavdevice 58. 5.100 / 58. 5.100 libavfilter 7. 40.101 / 7. 40.101 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 3.100 / 5. 3.100 libswresample 3. 3.100 / 3. 3.100 libpostproc 55. 3.100 / 55. 3.100 [video4linux2,v4l2 @ 0x1f601c0] Compressed: mjpeg : Motion-JPEG : 160x120 /dev/video1: Immediate exit requestedSo the MJPEG stream seems Ok. I also ran
ffplay /dev/video1and the stream is OK.Any ideas why this is not working? The virtual video resolution is 160x120 (it is a thermal cam via SPI video), that might be a problem?
