image - FFmpeg 破坏了我的图像

Question

现在我正在尝试使用大约 83 个图像来渲染一个读取我的图像文件夹的视频。我正在使用这个 FFMPEG 片段:

 ffmpeg -f image2   -i images/*.jpg  -b 450k -r 30  zoom100.avi  2>&1

但我真的很沮丧，FFMPEG 总是用第一个图像替换我所有的图像。它还为我创建的视频大约有 2 帧长
这里是 FFMPEF 反馈

Answer 1

不要使用 *单独不使用-pattern_type glob :否则它将假定第一张图像是唯一的输入，其余的是输出。如果使用 -y，这尤其危险。因为它会在不询问您的情况下覆盖输入图像。

全局模式

ffmpeg -framerate 30 -pattern_type glob -i "images/*.jpg" output

Windows 上可能不支持。

序列模式

ffmpeg -framerate 30 -i images/%04d.png output

假设您的输入名为 0001.png , 0002.png , 0003.png ， ETC。
