  • FFmpeg saving rtmp live stream cuts off after 3 minutes

    20 janvier 2013, par user1636922

    I was playing with ffmpeg and was able to save a live stream to a file. The command to do so is :

    ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -f h264 test.flv
    </ip>

    However, I have tested this twice, and both times ffmpeg stops after grabbing 3:28 worth of live video.

    The entire output is here :

    Although I don't see any errors. It just looks like ffmpeg thought the stream had ended ? But that's not possible since it's a live stream.
