[M4IF Technotes] ´ð¸´: [M4IF Technotes] yuv2avi

It’s very easy to write the application by using avilib.
For example, the yuv format is YUV420. pieces of code as follow:
     // AVI write handle
	avi_t*  pAviHandle;
	char VideoFmtYV12[4] = // YUV420
	{
		'Y','V','1','2'
	};
	pAviHandle = AVI_open_output_file("avi_yuv.avi");
	if(! pAviHandle)
	{
		printf("avi file open failed \n");
		return -1;
	}
	// set video format
	AVI_set_video(pAviHandle, 
		          width, // width 
				 height, // height
				 frame_rate,  // fps
				 //VideoFmtBvm4
				 VideoFmtYV12
				);
	// every frame(width*height + 1/4*width*height +
1/4*width*height)(y,u,v)
	// get the yuv data yourself	
	do {
		AVI_write_frame(pAviHandle,yuv_yuv_length);
	} while(1)
	// close open file
	AVI_close(pAviHandle);
After finished, try WMP or graphedit to test. It should be work for I
have written before.
Best,
Limin
