  • FFMPEG : RTSP re-stream dies randomly

    14 mai 2018, par stevendesu

    I have a security camera streaming RTSP, and I wish to re-stream this to an RTMP ingest server. For now I’m using my laptop as an ffmpeg proxy, but eventually I’ll use a raspberry pi or something similar (cheap/small)

    Here’s the command I’m using (pretty simple) :

    ffmpeg -i rtsp://@10.0.0.16:554/1/h264major -c:v libx264 -c:a none -f flv rtmp://output/camera_stream

    This works but after a minute or two the stream dies. Here’s the output :

    The camera is pretty cheap (from China) so it’s likely I’m getting bad data from it or it’s cutting out for a few seconds at a time. Ideally I would need ffmpeg to handle this well (ignore bad data, wait as long as necessary for good data to resume encoding)

    Using ffplay to check out the RTSP stream, I get output like the following :

    Then eventually the video just freezes. The first time it froze after around 5 minutes, but I wasn’t able to say definitively if it froze the instant 44 packets were dropped or if it froze randomly later. So the second time I stared intently.... for 21 minutes. Then I got bored of it not freezing, turned to pet my cat, and when I looked back 15 seconds later it was frozen. I think it only breaks when no one is watching it.

    What I can say definitively is :

    • While running normally, M-V hovers around 0 (anywhere between -0.01 and +0.01)
    • Once frozen, M-V begins to count down into negative numbers without stopping - although at a rate slower than -1 per second
    • While running normally, aq is 0KB and vq is a positive number (I think it was 30KB or so ?)
    • Once frozen, vq is also 0KB

    It’s a really cheap camera with a crummy power supply that goes out if you breathe on it, so it’s likely the camera is going temporarily offline during this time — but I’d like ffmpeg to wait out a timeout and resume streaming when it sees the camera again.
