我正在用 38,179 张图像制作视频。ffmpeg 成功制作了视频，但只包含前 20,998 张图像。它不包含最后 17xxx 张图像。我运行的是 Windows 7 64 位。
这些文件都在同一个目录中，名为 1000000.jpg - 1038179.jpg。
这是我使用的命令：
ffmpeg -r 16 -i 1%6d.jpg -r 16 video.mp4
我怎样才能让它包含所有图像？
这是输出的最后一屏：

答案1
我在 Linux 和 Windows 上遇到了同样的问题。对我来说，解决方案是观察转换在 0 字节的图像上停止。当我删除该图像时，ffmpeg 继续处理其余图像。
答案2
我遇到了类似的问题。我不知道发生了什么，但当我多次复制最后一帧并将其重命名为更高的数字时，我得到了我想要的视频。
答案3
尝试调整图像大小，最好使用“不带前导零”重命名方案（'filename-%d.png'）。在我的情况下，这种方法很有效。
或者，将 fps 调整为较低或均匀的值，奇怪的是，在这些情况下它对我有效，但没有证据表明这些特定设置存在错误或已知问题。
