FFmpeg r12430 build

Introduce:

FFmpeg is a complete solution to record, convert and stream audio and video. It includes libavcodec, the leading audio/video codec library. FFmpeg is developed under Linux, but it can compiled under most operating systems, including Windows.

H264 decoding/encoding should be ehanced huge in this version if you have multi-core CPUs

eg:
ffmpeg -i input.avi -threads 2 -acodec libfaac -ab 64K -b 500K -vcodec libx264 -s 640x480 new.mp4

NOTE: this version is compiled by the latest GCC4.3 and optimized for intel core2 architecture.

You can download it directly by the following address

Configured by:

./configure --prefix=d:/nextcodeccode/svn_build --enable-memalign-hack --enable-shared --disable-static --disable-encoder=snow --disable-decoder=ac3 --disable-decoder=vorbis --disable-encoder=vorbis --disable-vhook --enable-ffplay --disable-ffserver --disable-mpegaudio-hp --enable-pthreads --enable-liba52 --enable-nonfree --enable-libamr-nb --enable-libamr-wb --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libgsm --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-avisynth --enable-gpl --enable-swscale --enable-avfilter --enable-avfilter-lavf --enable-demuxer=vfwcap --enable-demuxer=rm --extra-cflags="-I/usr/local/include -I/usr/local/include/SDL -mtune=core2 -march=core2" --extra-ldflags=-L/usr/local/lib --extra-libs=-lpthreadGC2

Note:
output_example.exe, tools/cws2fws.exe, tools/pktdumper.exe, tools/qt-faststart.exe, tools/trasher.exe are also compiled

Addins:
1) how to make a mp4 streamable with Adobe Flash Player?
You can use the following command to make a mp4/mov/3gp file<encoded with H264+AAC> streaming feature which is compatible with the latest Adobe Flash Player
eg:
qt-faststart.exe input.mp4 output.mp4

Now,output.mp4 can be rendered instantly by Flash Player

2)How to use avfilter?

a)To vertically flip a video, you would do:

./ffplay -vfilters vflip input_video.avi
But the following commands(apply two vflip filter) will result in the orginal picture
./ffplay -vfilters vflip,vflip input_video.avi

b)To scale video to specific dimension, you would do:
./ffplay -vfilters scale=640:480 input_video.avi

c)avfilter can accepts many input files and generate many output files at the same time.
I will elaberate this feature on next major builder

Enjoy it and test it

Thanks
