I got deeper into FFMPEG when I wanted to transcode into FLV (Flash Video) and it works very well. I developed the Riva FLV Encoder, a GUI for FFMPEG. Update 26.10.2006: This tutorial is a little outdated as there were many changes in FFMPEG like the switch from CVS to Subversion and the workflow to compile FFMPEG under Windows has become more difficult. For the new tweaks check this tutorial.
MSYS是什么,他与CYGWIN有什么区别? [编辑] Use FFMPEG Copy your compiled ffmpeg.exe from your MSYS directory to the directory where you like to transcode with ffmpeg Open the Dos-Shell and change to the directory where you copied the ffmpeg.exe Copy a test.mpg into your directory and enter the following command: ffmpeg -i test.mpg -ab 56 -ar 22050 -b 500 -r 15 -s 320x240 test.flvYour first FLV should be encoded now [编辑] Render Images from a Video Enter command: ffmpeg -an -y -t 0:0:0.001 -i test.flv -f image2 test%d.jpgHINT: With -t you set the length of images to be extracted. Above we entered 1 millisecond the extract one image. If you miss this parameter all images of the video will be extracted [编辑] ZLib Support (e.g. for TSCC and Quicktime codecs). This should be compiled into FFMPEG. It is not an explicit compile in the configure statement. Do the following steps and after configure you should see that zlib is "on". Download and compile ZLib Extract the files to your mysys directory Change the directory in MSYS to that directory Enter command ./confuguremakemake install.[编辑] AC3 Support Add "--enable-a52 --enable-gpl" to your configure command [编辑] 3GP Support If you want to enable 3GP support you have to add the AMR audio codec. Download the TS26.104 REL-5 V5.1.0 26104-5??.zip here. Extract the codec into libavcodec/amr_float and add "--enable-amr_nb" to your configure command [编辑] XVID Support (thanks to garvin.thornten at datel.co.uk) Download and install the codec from www.xlib.org (see xvidcore-xxxx/doc/install). Add "--enable-xvid --enable-gpl" to your configure command. When compiling with xvid codec in MinGW or cygwin you will get a "mkstemp" error when compiling "xvidff.c". To fix this edit "libavcodec/xvidff.c" and add the following after the #includes. This will probably be fixed in a future ffmpeg release: ´ /* Added for windows compile ----------------- */#include int xvid_ff_2pass(void *ref, int opt, void *p1, void *p2); void xvid_correct_framerate(AVCodecContext *avctx); int mkstemp(char* template)char temppath[512];if(GetTempPath(512,temppath)!=0){ if(GetTempFileName(temppath,"fil",0,template)!=0) { FILE *pFile; pFile=fopen(template,"w+"); if(pFile!=NULL) return (int)pFile; }} return -1;}/* ------------------------------------------- */ |
也有人说 安装个php的扩展就好了 php_ffmpeg
然后用它的函数操作即可
