BirdDog Cameras and SRT

[bchah]

In a streaming test from a BirdDog X1 camera, the SRT connection seemed to establish then immediately terminate, even though the camera appeared to be running the stream data still. In the OME logs we see:

Any idea why the immediate disconnection could be occurring? Could it be related to the "Could not get option: 4" line? We double and triple checked the stream encoding settings and we are sure they are compatible. OME even reports the codecs as expected:

If anybody else has tried this hardware or sees something suspicious in the logs, any clues or experiences with BirdDog cameras would be appreciated :)

Is there anybody at Airensoft who can take a look at this? 🙏

"Could not get option: 4" is probably not related.
We also don't have a BirdDog camera, so we'll need your help to check this out. Maybe next week... or so. (This week is too busy.)

Thank you 🙏 I don't have a BirdDog camera either but whenever you are able to provide a test endpoint, I can arrange for a customer to send a test stream.
