FFmpeg毁掉我的图片
FFmpeg毁掉我的图片
提问于 2015-09-14 05:58:24
Rightnow我正在尝试渲染一个Video reading my image文件夹，其中包含大约83个图像。我正在使用这个FFMPEG片段：
ffmpeg -f image2 -i images/*.jpg -b 450k -r 30 zoom100.avi 2>&1但是我真的很沮丧，FFMPEG总是用第一张图片替换我所有的图片。它还创建了大约2帧长的视频，这里是FFMPEF反馈

不要在不使用-pattern_type glob的情况下单独使用*：否则它将假定第一个图像是唯一的输入，其余的是输出。如果使用-y，这尤其危险，因为它会在没有询问您的情况下覆盖输入图像。
Glob模式
ffmpeg -framerate 30 -pattern_type glob -i "images/*.jpg" output可能在Windows上不受支持。
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等。

ffmpeg -f image2 -i images/%04d.jpg -b 450k -r 30 zoom100.avi否则，shell将其展开，其中第一个图像是输入文件，其他图像是输出文件。这样，它们都是输入文件。
