我有 28,000 张图像需要转换成电影。我试过
mencoder mf://*.jpg -mf w=640:h=480:fps=30:type=jpg -ovc lavc -lavcopts vcodec=msmpeg4v2 -nosound -o ../output-msmpeg4v2.avi
但它似乎在 7500 帧时出现了问题。
这些文件被命名为 webcam_2007-04-16_070804.jpg webcam_2007-04-16_071004.jpg webcam_2007-04-16_071204.jpg webcam_2007-04-16_071404.jpg 直到 2008 年 3 月左右。
有没有另一种方法可以将文件名传递给mencoder,这样它就不会中途停止?
