    It works without errors, but when I try to play output.264 using ffplay :

  • error : av_interleaved_write_frame() : Unknown error

    12 avril 2014, par John Qualis

    I am new to ffmpeg. I am trying to stream my webcam using ffmpeg (x264 encoding) on a windows machine to ffserver on a linux server and restream it. I am getting the following error : av_interleaved_write_frame() : Unknown error
    I checked about it on the net and came across mails which said it could be related to version mismatch between ffmpeg and ffserver. I made sure that all libraries that are used by ffmpeg and ffserver have the same version. I am still getting this error. Appreciate any help in solving this issue.

    I am using the following command :

     .\ffmpeg.exe -f dshow -i video="Webcam C170":audio="Microphone (3- Webcam C170)" -an -g 94 -vcodec libx264 -b:v 512k -r 30 -f flv http://AA.BB.CC.DD:8090/feed1.ffm

    I get the followoing errors -

      [dshow @ 0003f240] real-time buffer 101% full! frame dropped!
    
    Last message repeated 1 times
