发表于

(The original link)

STEP 1 - Preparations

Install Xcode(include git)

STEP 2 - Downloading all necessary source codes

Download all file into a folder named FFmpeg on the your disk:

1、FFmpeg source code

  • Open the Terminal
  • write the following in the Terminal : git clone git://git.videolan.org/ffmpeg.git ffmpeg
    Because FFmpeg needs several extra codecs you need some other source codes too.

2、MP3lame source code

  • Go to http://lame.sourceforge.net/download.php
  • Download lame source

3、Ogg, Vorbis and Theora source code

  • Go to http://xiph.org/downloads/
  • Download the following sources: libogg source , libvorbis source and libtheora source.

4、X264 source code (for H264 support)

  • Open the Terminal
  • write the following in the Terminal : git clone git://git.videolan.org/x264.git

5、VP8 source code

  • Open the terminal
  • write the following in the Terminal : git clone git://review.webmproject.org/libvpx.git

6、Xvid source code

  • Go to http://www.xvid.org/Downloads.43.0.html
  • Download Xvid source code

All source code has been downloaded here.

STEP 3 - Compiling all source codes

Open the Terminal and copy paste every line below marked BOLD.

DISK_ID=$(hdid -nomount ram://26214400) && newfs_hfs -v tempdisk ${DISK_ID} && diskutil mount ${DISK_ID} && SOURCE="/Volumes/tempdisk/sw" && COMPILED="/Volumes/tempdisk/compile" && mkdir ${SOURCE} && mkdir ${COMPILED} && export PATH=${SOURCE}/bin:$PATH

Compiling YASM:

cd ${COMPILED} || exit 1
cd yasm-1.2.0
./configure --prefix=${SOURCE} && make -j 4 && make install

Compiling LIBVPX

cd ${COMPILED}
cd libvpx
./configure --prefix=${SOURCE} --disable-shared && make -j 4 && make install

Compiling LAME

cd ${COMPILED}
cd lame-3.99
./configure --prefix=${SOURCE} --disable-shared --enable-static && make -j 4 && make install

Compiling XVIDCORE

cd ${COMPILED}
cd xvidcore
cd build/generic
./configure --prefix=${SOURCE} --disable-shared --enable-static --disable-assembly && make -j 4 && make install
rm ${SOURCE}/lib/libxvidcore.4.dylib

Compiling X264

cd ${COMPILED}
cd x264
./configure --prefix=${SOURCE} --disable-shared --enable-static && make -j 4 && make install && make install-lib-static

Compiling LIBOGG

cd ${COMPILED}
cd libogg-1.3.0
./configure --prefix=${SOURCE} --disable-shared --enable-static && make -j 4 && make install

Compiling LIBVORBIS

cd ${COMPILED}
cd libvorbis-1.3.2
./configure --prefix=${SOURCE} --with-ogg-libraries=${SOURCE}/lib --with-ogg-includes=/Volumes/tempdisk/sw/include/ --enable-static --disable-shared && make -j 4 && make install

Compiling LIBTHEORA

cd ${COMPILED}
cd libtheora-1.1.1
./configure --prefix=${SOURCE} --with-ogg-libraries=${SOURCE}/lib --with-ogg-includes=${SOURCE}/include/ --with-vorbis-libraries=${SOURCE}/lib --with-vorbis-includes=${SOURCE}/include/ --enable-static --disable-shared && make -j 4 && make install

Compiling ZLIB

cd ${COMPILED}
cd zlib
./configure --prefix=${SOURCE} && make -j 4 && make install
rm ${SOURCE}/lib/libz*dylib
rm ${SOURCE}/lib/libz.so*

Compiling FFMPEG

cd ${COMPILED}
cd ffmpeg
export LDFLAGS="-L${SOURCE}/lib"
export CFLAGS="-I${SOURCE}/include"
./configure --prefix=${SOURCE} --enable-gpl --enable-pthreads --disable-ffplay --disable-ffserver --enable-libvpx --disable-decoder=libvpx --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-avfilter  --enable-filters --arch=x86 --enable-runtime-cpudetect && make -j 4 && make install

After doing all the hardcore compiling you are awarded a FFmpeg binary in the sw/BIN folder. Here is my binary.

Test：

$> mkdir frames
$> ./ffmpeg -i input.mp4 -r 10 frames/frame%03d.png
$> ./ffmpeg -t 25 -ss 00:00:01 -i loading.mp4 loading.gif

Copy the ffmpeg binary to /usr/local/bin folder so that you can use ffmpeg command anywhere in your terminal directly.

Convert mp4 to gif

ffmpeg -i loading.mp4 -s loading.gif
ffmpeg -t 25 -ss 00:00:01 -i loading.mp4 -s 540x960 loading.gif

-s：adjust gif size

ffmpeg -t 25 -ss 00:00:01 -r 15 -i loading1.mp4 -s 540x960 loading2.gif

-r：adjust frame rate

ffmpeg -i loading.mp4 -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' loading1.mp4

Add a logo to the lower left corner

Three Steps For Vedio Clip

1、Convert mp4 to png

ffmpeg -i input.mp4 -r 10 frames/frame%03d.png

2、Remove unnecessary files，rename files according to the serial number.

i=0;dir=$(eval pwd); for name in $(ls $dir);do i=$(($i+1));p=$(eval printf "%03d" $i);mv $name frame$p.png; done

3、Convert png to mp4

ffmpeg -r 10 -f image2 -i frame%03d.png -pix_fmt yuv420p loading.mp4
