FFMPEG:从带有时间戳的图像创建电影 [英] FFMPEG: create movie from timestamped images

问题描述

我正在尝试从包含网络摄像头图像的文件夹中制作一个小型电影文件.

Im trying to make a small movie file from a folder with webcam images.

它们的命名如下:
00-00-38.jpg
00-05-37.jpg
00-10-37.jpg
00-15-37.jpg

They are named like this:
00-00-38.jpg
00-05-37.jpg
00-10-37.jpg
00-15-37.jpg

H-M-S.jpg格式

H-M-S.jpg format

尽管我尝试了patterntype glob和更简单的命令，但我无法使它正常工作.

Although i tried patterntype glob and simpler commands i cannot get it to work.

这是我尝试过的:

ffmpeg -r 1 -pattern_type glob -i '*.jpg' -scale=720:-1 -c:v libx264 out.mp4 
(got only one image)
ffmpeg -r 25 -i *.jpg -vf "scale=720:-1" output.mp4
(same size as a jpg file but no video)

控制台输出:

ffmpeg -framerate 1 -pattern_type glob -i "*.jpg" -vf scale=720:-1 -c:v libx264 -pix_fmt yuv420p out.mp4

视频为364KB，没有任何视频.

The video is 364KB without any video.

推荐答案

我总是按照以下方式进行操作:

I've always done something along the lines of:

a=0
for i in *.jpg; do
    new=$(printf "/home/Movies/jpgs/%04d.jpg" "$a")
    cp -f "$i" "$new"
    let a=a+1
done

要以正确的顺序获取文件，只要输入数字不单调，其他任何方法都会破坏编码.

to get the files in the right order, anything else breaks the encoding as soon as the input numbers are non-monotonic.
