可能是一个快速的anwser，但我第一次尝试这样做。我有77张jpeg图片，我将它们重命名为000.jpg - 076.jpg。下一步是使用ffmpeg，这是我的命令语句：
ffmpeg -f image2 -r .1 -i %d.jpg -r 25 test.avi
它创建一个带有10个图像的avi，每个10秒，为什么只有10个？我在ffmpeg命令中尝试了％d.jpg的其他迭代但没有成功。
感谢所有的帮助！

在这种情况下，它应该是％03d，因为你有三位数。我不确定它是如何运行的，但我不认为这会导致问题。我唯一能想到的是，在你的图像序列中，图像＃11出现故障（命名不正确）。如果图像不是全部按顺序排列，则ffmpeg假定序列在找不到下一个数字时完成。要么通过并检查，要么在控制台的ffmpeg文档中运行脚本的变体（如果你在Windows上，则为MinGW）以自动重命名它们。
如果仍然无法解决问题，请发布整个ffmpeg控制台输出（在ffmpeg命令中传递“-report”，它会保存带有日志的文本文件）。
