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

可以看出:
这意味着什么?已弃用的像素格式,请确保您确实正确设置了范围
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
- >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。
