我正在尝试使用ffmpeg从jpeg图像创建视频。生成的视频应为x264或x265格式。
我有一个包含36张图片的目录。每个图像大小约为6000万像素。它们的名称如下：
我在SO中阅读了文档和几个帖子，我来写一个批处理文件来调用ffmpeg，如下所示：
ffmpeg.exe -r 1/5 -start_number 0 -i %1\frame%%05d.jpg -c:v libx264 -vf "fps=1,format=yuv420p" out1.mp4
当我运行此命令时，我从ffmpeg获取此输出，这很奇怪：
C:\Users\m\Desktop\ffmpeg-20170702-c885356-win64-static\bin>ffmpeg.exe -r 1/5 -start_number 0 -i "C:\Resized"\frame%05d.jpg -c:v libx264 -vf "fps=1,format=yuv420p" out1.mp4

如何解决这些问题并从这些框架中创建视频？
在得到一些回复之后，我注意到h264不支持最终解析，所以我转换为使用VP9并且我正在使用此命令：
ffmpeg -i %1\frame%%05d.jpg -c:v libvpx-vp9 -b:v 2M -c:a libvorbis output.webm
我得到了正确的帧数，但我无法使用VLC播放输出。
答案 0 :(得分：0)
当我们只有36帧时，它正在尝试处理超过36帧。
您的输入速率设置为1/5即显示每个帧5秒，但您的输出速率设置为1（fps=1），因此ffmpeg将每帧复制4次（除了最后一个）。
直到第25帧，大小为零，比特率为N / A，在第25帧之后，大小变为零。
报告大小和比特率，因为编码后流是多路复用的，因此存在一些滞后。
在第47帧之后，FPS变为零。
它的帧27，并且该FPS值是处理速度。您的最终处理速度为0.03x，即0.03 x 1 fps，因此fps读数将向下舍入或截断为0.0 - ＆gt;不是错误。
我无法播放输出视频。
两个可能的原因：
许多视频播放器无法播放低帧率视频。 5往往是最安全的。所以fps=5。另外，将-r 1/5更改为-framerate 1/5。
其他原因可能是帧大小。某些播放器可能无法播放具有较大帧的视频，这可能是由于其大小本身或不符合任何有效的H.264级别。如果是这种情况，您可能需要缩小流。
