Still picture fine, but no response when tapping the camera
Hi all! 
I have a foscam fi8910w camera, perfectly working and set up. I have a raspi 4 with homebridge running and ffmpeg installed. The problem is that, I have the still image each 10 seconds, but I cannot stream the video! When I tap on the camera in the home app, I get "no response" and the camera gets greyed out and no more still image gets refreshed. Strange thing, in the log of homebridge, no "starting live feed" comes up, check it out: 

0|homebridge  | [3/25/2020, 12:47:56] [Camera-ffmpeg] Snapshot from Foscam at 320x240
0|homebridge  | [3/25/2020, 12:48:07] [Camera-ffmpeg] Snapshot from Foscam at 320x240

0|homebridge  | [3/25/2020, 12:59:04] [Camera-ffmpeg] Snapshot from Foscam at 320x240

These are the 4 last messages, but in the meanwhile I tapped to get the live feed. The camera is greyed out and no more pictures are shown. I have to close and reopen the Home app to make the pictures refresh. 
If I try to start the feed from ip, it works super well via the ip and browser (I use safari).

**This is what ffmpeg gives me when I type ffmpeg**:

Anyone experienced this problem before? Thank you very much for any help!
