4、install qt-faststart

This is a useful tool included with FFmpeg that rearranges a file with H.264 video, "such that the moov atom is in front of the data, thus facilitating network streaming". Basically, it allows web movies to start playing before they are completely downloaded. Usage: qt-faststart input.foo output.foo.

root@ran-desktop:/home/ran/ffmpeg# make tools/qt-faststart
CC    tools/qt-faststart.o
LD    tools/qt-faststart
rm tools/qt-faststart.o

sudo checkinstall --pkgname=qt-faststart --pkgversion "4:SVN-r`LANG=C svn info | /

grep Revision | awk '{ print $NF }'`" --backup=no --deldoc=yes --fstrans=no /

--default install -D -m755 tools/qt-faststart /usr/local/bin/qt-faststart
