拼抢每4个文件 [英] Grabbing every 4th file
问题描述
我有16000 JPG从webcan screeb采集我让运行了一年的一端指向后面持平。我想找到一种方法，抓住每4个图像，这样我可以把它放到另一个目录中，以便以后我可以把它们拍成电影。有一个简单的bash脚本或者linux下的其他方式，我可以做到这一点。
I have 16,000 jpg's from a webcan screeb grabber that I let run for a year pointing into the back year. I want to find a way to grab every 4th image so that I can then put them into another directory so I can later turn them into a movie. Is there a simple bash script or other way under linux that I can do this.
它们被命名为像这样......
They are named like so......

似乎已经奏效。
在我origonal POST错误的情侣。实际上有28万的图像和命名了。
/home/baldy/Desktop/webcamimages/webcam_2007-05-29_163405.jpg
/home/baldy/Desktop/webcamimages/webcam_2007-05-29_163505.jpg
/home/baldy/Desktop/webcamimages/webcam_2007-05-29_163605.jpg
Seems to have worked. Couple of errors in my origonal post. There were actually 280,000 images and the naming was. /home/baldy/Desktop/webcamimages/webcam_2007-05-29_163405.jpg /home/baldy/Desktop/webcamimages/webcam_2007-05-29_163505.jpg /home/baldy/Desktop/webcamimages/webcam_2007-05-29_163605.jpg
我跑了。
CP $（LS | awk的'{NR ++;如果（NR％10 == 0）打印$ 0}'）../ newdirectory /
I ran. cp $(ls | awk '{nr++; if (nr % 10 == 0) print $0}') ../newdirectory/
这似乎已复制图像。 70-900每天从它的外观。
Which appears to have copied the images. 70-900 per day from the looks of it.
现在我跑
男人codeR MF：//*.jpg -mf W = 640：H = 480：FPS = 30：类型= JPG -ovc lavc使用-lavcopts V codeC = msmpeg4v2 -nosound -o ../output- msmpeg4v2.avi
Now I'm running mencoder mf://*.jpg -mf w=640:h=480:fps=30:type=jpg -ovc lavc -lavcopts vcodec=msmpeg4v2 -nosound -o ../output-msmpeg4v2.avi
我会让你知道电影是如何工作的。
I'll let you know how the movie works out.
更新：影片没有工作。
只有从2007年图像它，即使该目录下有2008年为好。
webcam_2008-02-17_101403.jpg webcam_2008-03-27_192205.jpg
webcam_2008-02-17_102403.jpg webcam_2008-03-27_193205.jpg
webcam_2008-02-17_103403.jpg webcam_2008-03-27_194205.jpg
webcam_2008-02-17_104403.jpg webcam_2008-03-27_195205.jpg
UPDATE: Movie did not work. Only has images from 2007 in it even though the directory has 2008 as well. webcam_2008-02-17_101403.jpg webcam_2008-03-27_192205.jpg webcam_2008-02-17_102403.jpg webcam_2008-03-27_193205.jpg webcam_2008-02-17_103403.jpg webcam_2008-03-27_194205.jpg webcam_2008-02-17_104403.jpg webcam_2008-03-27_195205.jpg
如何修改我的男人codeR线，以便它使用的所有图像？
How can I modify my mencoder line so that it uses all the images?
