FFMPEG:自定义序列输入图像 [英] FFMPEG : custom sequence input images
本文介绍了FFMPEG:自定义序列输入图像的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我用一组图像创建了一个视频.
I created a video from a set of images.
命令如下:
ffmpeg -i bg.jpeg -i img_%d.png -filter_complex overlay=5:H-h-5[b]-shortest testvid.mp4
问题:
输入-i img_%d.png表示img_0.png，img_1.png，img_2.png，...
The input -i img_%d.png means img_0.png, img_1.png, img_2.png, ...
但是我有这样的自定义序列:{img_0.png, img_1.png, img_1.png, img_2.png, img_1.png, img5.png, img_4.png}
But I have custom sequence like this: {img_0.png, img_1.png, img_1.png, img_2.png, img_1.png, img5.png, img_4.png}
问题:
我可以将图像序列放入ffmpeg的输入中吗?
Can I put my image sequence into input of ffmpeg?

推荐答案
您可以将concat解复用器与自定义序列一起使用.
You can use the concat demuxer with the custom sequence.
首先，创建一个文本文件:
First, create a text file:
file 'img_0.png'
file 'img_1.png'
file 'img_1.png'
file 'img_2.png'
file 'img_1.png'
file 'img5.png'
file 'img_4.png'
然后运行
ffmpeg -i bg.jpeg -f concat -r 25 -i list.txt -filter_complex "overlay=5:H-h-5" -shortest out.mp4
编辑:对于PNG和大多数其他图像格式，应明确指定r以初始化列表中每个图像条目的持续时间.
Edit: For PNG and most other image formats, r should be expressly specified to initialize a duration for each image entry in the list.
