FFmpeg capture RTSP stream only audio, black screen

I have a Foscam IP camera for which i have access to the RTSP address. If i use VLC, the stream is working fine. I wanted to capture it using FFmpeg, using the command ffmpeg -i <address> -codec copy -t 10 out.mov. All i get though is audio with a black screen. From the logs i get

Input file #0 (rtsp://*:554/videoMain):
  Input stream #0:0 (video): 226 packets read (2300933 bytes);
  Input stream #0:1 (audio): 169 packets read (81120 bytes);
  Total: 395 packets (2382053 bytes) demuxed
Output file #0 (camera.mov):
  Output stream #0:0 (video): 1 packets muxed (81865 bytes);
  Output stream #0:1 (audio): 168 packets muxed (80640 bytes);
  Total: 169 packets (162505 bytes) muxed
0 frames successfully decoded, 0 decoding errors

So, i don't know why only 1 packet gets muxed from the video stream. Anyone had this issue?

Which codec does the camera use? Quicktime (.mov) does not support all codecs. – Eugen Rieck – 2019-01-26T21:05:38.660

@EugenRieck i forgot to mention that i actually had it going once, and .mov worked just fine. Recently i discovered that ommiting the -t option will make it work but i need to stop it manually. – user3808318 – 2019-01-27T07:41:18.670

Looks like a very large GOP ... try -t 60 and report back – Eugen Rieck – 2019-01-27T09:31:22.833
