Sorry for that, now I'm leaving the computer, but o back in some hour.
Unfortunately I lost the access to the camera, but I'll get another models
soon.
The difference I see on the requests is that, second cam return
"content-length" header. So I'm thinking to make a proxy to remove it, or
may I can edit the code from ffmpeg to ignora that.
Thank you, I'll public my progress
