  • 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 :

    bash-4.2$ ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -vcodec libx264 -f h264 test.flv

    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.

  • ffmpeg + ffserver : "Broken ffmpeg default settings detected"

    18 octobre 2012, par Chris Nolet

    I'm just trying to connect ffmpeg to ffserver and stream rawvideo.

    I keep getting the error : broken ffmpeg default settings detected from libx264 and then Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height from ffmpeg before it exits.

    I'm launching ffmpeg with the command : ffmpeg -f x11grab -s 320x480 -r 10 -i :0.0 -tune zerolatency http://localhost:8090/feed1.ffm

    My ffserver.conf file (for ffserver) looks like this :

  • FFMPEG Error VC1 to X264 (maybe decoding VC1)

    29 janvier 2013, par Xatian

    I am encountering the following error when transcoding using FFMPEG.
    It seams to me that it's an error decoding the VC1 format and has actually nothing to do with the target format (x264) I want to transcode.

    I tracked the error to this source-file :

    http://cekirdek.pardus.org.tr/ ismail/ffmpeg-docs/vc1_8c-source.html

    but I don't know how to set the profile to a value != simple.
