Gray image on h264 with Panasonic cams

Netcam Studio Problems & Bugs
1

Hi,

I have 2 cams that show a gray image on h264.

Example:

It’s a Panasonic WV-SP306.
I use this custom URL (RTSP_HTTP): rtsp://admin:xxx@10.101.4.16/MediaInput/h264

If I re-save the video source, I can see the image for 2 seconds, after that, I see the gray image again. Switching to other RTSP modes doesn’t help.

I had the same issue with another cam (Panasonic WV-SF135), which uses the RTSP H264 preset. There I can solve it for a while by switching back and forth betweens RTSP H264 and MJPEG.

Hi,
Most likely the stream is not the correct one for the h.264 encoding. Suggestions:
For WV-SP306
-use the same URL rtsp://admin:xxx@10.101.4.16/MediaInput/h264 in VLC and see the result.
-why use rtsp_http? usually it is rtsp_tcp.
-I am not sure, but is seems that there are versions of h.264. Test to change that.
-there is a predefined template for the Panasonic WV-SP306. Does any of the settings work?
-the camera support ONVIF. Add the camera to NCS with the tab ONVIF source.
-I have also rtsp://IP//ONVIF/MediaInput

For WV-SF135
-test also with VLC.
-It use ONVIF so add the camera using the ONVIF Source tab.
-I am not sure, but is seems that there are versions of h.264. Test to change that.

Hi,

switching to Onvif (or rtsp_tcp) does the same. When connecting via VLC, it works as expected.

-this is VLC and that is not correct. (maybe you did the pixels :slight_smile:)

-switch to RTSP_UDP and test
-Also go into the configuration of the camera and see if you can change which h.264 that is used…
