//文件位置指示器自己变化了.
It depends on your site/app. The general rules are something like this:
Saving in a cookieworks well if the number of simultaneous users is high and the size of the data is relatively low. Obviously cookies are publicly viewable so if it is sensitive such as email then it should be encrypted.
原文帖链接：
fseek( fyuv, 0, SEEK_SET );
i_frame_total = i_size / ( param->i_width * param->i_height * 3 / 2 )
A. i_frame_total = 0;
/* read a frame */
{
2. 这次的分析基本上已经将代码中最难理解的部分做了阐释,对代码的主线也做了剖析,如果这个主线理解了,就容易设置几个区间,进行分工阅读,将各个区间击破了.
}
这里看一下x264_picture_t和x264_frame_t的区别.前者是说明一个视频序列中每帧的特点.后者存放每帧实际的象素值.注意区分.
i_ret = Encode( ¶m, fin, fout );
Saving in the databaseworks well if the size of the data is large.
凡是出现for循环的地方都应该认真对待,热血传奇私服,这是我的一个体会,也是进入分层结构认真分析的好方法.
fprintf( stderr, "x264_encoder_encode failed/n" );
if( fread( pic->plane[0],www.jjj.com, 1, param->i_width * param->i_height, fyuv ) <= 0
{
Note. As others have said if your using a web farm then I would forget about saving in the session.
……
int i;
if( x264_encoder_encode( h,传奇战歌, &nal,今日新开传奇私服, &i_nal, pic ) < 0 )
}上面这段计算出输入文件的总帧数.
}
fread()函数一次读入一帧,分亮度和色度分别读取.这里要看到c语言中的File文件有一个文件位置指示器,调用fread()函数会使文件指示器自动移位,这就是一帧一帧读取的实现过程.
1. 进入x264.c中的main函数.
C. pic = x264_picture_new( h );
刚开始是读取默认参数,如果你设置了参数的话会修改param的.
{
int64_t i_size = ftell( fyuv );
