  • FFMPEG x264 MP4 Encoding all grey

    7 mars 2013, par Brianjs

    I am currently using FFMPEG v1.1 on CentOS 6.3.

    I configured FFMPEG with :

    ./configure --arch=x86_64  --enable-libmp3lame  --enable-librtmp  --enable-libtheora --enable-libvorbis  --enable-libx264 --enable-pthreads --enable-gpl --enable-runtime-cpudetect

    when I run a simple command to record live input to MP4 by :

    ffmpeg -f video4linux2 -s 640x480 -i /dev/video0 /home/irdb/Desktop/test.mp4

    I get nothing, just a grey screen with some artifacts around the edges. However when I run the same command as .MPG it comes out fine. I need it in MP4 format however.

    On a side note I am running x264-0.120 installed through yum

    My question is, is there a problem with the way I compiled ffmpeg ? Or is it possibly something else ?

    edit :

    Output from example as requested :

    # ffmpeg -f video4linux2 -s 640x480 -t 5 -i /dev/video0 -strict 2 /home/irdb/Desktop/test.mp4

  • Revision 20babf6d9d : Don't try to use getenv on windows phone/rt The getenv function doesn't exist t

    29 mai 2013, par Martin Storsjo

    Changed Paths :
     Modify /vpx_ports/arm_cpudetect.c



    Don’t try to use getenv on windows phone/rt

    The getenv function doesn’t exist there. In Visual Studio 2012,
    the function still existed in the link libraries even though
    it was hidden in the headers, but in the 2013 version it has been
    removed from the link libraries as well.
