  • Strange error [adding watermark to flv video with ffmpeg on linux centos 6]

    20 juillet 2012, par igor

    I have tried to do the job with following code :

    ffmpeg -i /home/igordr/video.flv -vf "movie=/home/igordr/wm.jpg [watermark]; [in][watermark] overlay=main_w/2-overlay_w/2:main_h/2-overlay_h/2 [out]" /home/igordr/outputvideo.flv

    Also tried :

    ffmpeg -i /home/igordr/video.flv -b:a 300k -ar 22050 -t 10 -f flv -s 352x288 -vf "movie = /home/igordr/wm.png [watermark]; [in][watermark] overlay =0:0 [out]" /home/igordr/out.flv

    I get errors :

    Unrecognized option 'vf'
    

    
Unrecognized option 'b:a'

    Also, I am interested, how I can add just one big image, before video starts, without watermark, and does it possible ?

    How can i check ffmpeg version, and install new one if it's old ?
