Get source code<\/p>\n

  • svn checkout svn:\/\/svn.ffmpeg.org\/ffmpeg\/trunk ffmpeg\n<\/li>\n

    Needs libfaac…
    \n
    \n<\/code><\/p>\n

    wget http:\/\/downloads.sourceforge.net\/faac\/faac-1.28.tar.gz\n<\/p><\/blockquote>\n

    hmmm… that seemed to require<\/p>\n

    yum install gcc-c++
    \n<\/code>\n<\/p><\/blockquote>\n

    to get g++ to work<\/p>\n

    Also needs x264
    \nBut x264 needs yasm…<\/p>\n

    wget http:\/\/www.tortall.net\/projects\/yasm\/releases\/yasm-0.8.0.tar.gz<\/p>\n

    OK, got yasm, now
    \nwget ftp:\/\/ftp.videolan.org:21\/pub\/videolan\/x264\/snapshots\/x264-snapshot-20091130-2245.tar.bz2<\/p>\n

    Be sure to .\/configure –enable-shared<\/p>\n

    There was an issue using libx264.so.76 on another system I maintain, had to fall back on libx264.so.72 . errors like<\/p>\n

    In function `X264_init':
    \n\/tmp\/ffmpeg\/libavcodec\/libx264.c:284: undefined reference to
    \n`x264_encoder_open_79' <\/code><\/p><\/blockquote>\n

    libx264.so.79 and ffmpeg from SVN seem to take care of that.<\/p>\n

    OK, at last we con configure ffmpeg with<\/p>\n

    .\/configure --disable-ffplay --disable-demuxer=v4l_demuxer --enable-libx264 --enable-gpl --enable-shared --enable-libfaac --enable-nonfree
    \n<\/code><\/p><\/blockquote>\n

    Lastly, always need to set env
    \nLD_LIBRARY_PATH=’\/usr\/local\/lib\/<\/p>\n

    Now, we can type<\/p>\n

    ffmpeg -y -i \/users\/w\/a\/waw\/red5\/webapps\/oflaDemo\/streams\/bob\/intro.flv -acodec libfaac -ab 96k -ar 44100 -vcodec libx264 -vpre hq -crf 22 -flags2 -bpyramid \/users\/w\/a\/waw\/red5\/webapps\/oflaDemo\/streams\/bob\/intro.mp4<\/code><\/p>\n

    Oops — almost forgot. Also need to set working directory to ffmpeg\/tools and make qt-faststart , then copy qt-faststart to \/usr\/local\/bin<\/p>\n","protected":false},"excerpt":{"rendered":"
