我正在用 Python 中的 RPI 制作延时摄影。
拍摄图像并将其存储在文件夹中：没有问题。但使用 FFMPEG 创建视频时我遇到了问题。
在 X 幅图像之后，脚本开始创建视频。结果视频只有第一帧，并且会用第一帧覆盖文件夹中的所有图像（？！）。没有错误消息。
那么我做错了什么？

我已经尝试过这个并且一切正常：https://lindevs.com/install-ffmpeg-on-raspberry-pi/
答案1
快速解决方案：将输入文件名放入单引号（ffmpeg … -i '…/*.jpg' …）中。
更长的解释：问题在于，*在 ffmpeg 看到它们之前，你的 shell 就已经将它们扩展为文件名列表。
因此，你原来的命令是错误的：
ffmpeg -f image2 -framerate 1 -pattern_type glob -start_number %d \
-i /media/julien/USBKEY/capture_%d/%d/*.jpg \
-r 5 -c:v libx264 -pix_fmt yuv420p \
/media/julien/USBKEY/capture_%s/%d/out%d.mp4 -y
ffmpeg 将使用图像列表进行调用，本质上：
-i image1.jpg image2.jpg …
对于 ffmpeg，第二个图像文件被解释为输出文件名。由于您已传递-y，ffmpeg 将很乐意覆盖此图像。（请注意，-y作为全局选项，应放在参数列表的第一位。）
你需要做的是引用通配符。这样，你的 shell 就不会解释它并将其传递给 ffmpeg，ffmpeg 会在内部将通配符扩展为文件夹中的图像列表。
ffmpeg -f image2 -framerate 1 -pattern_type glob -start_number %d \
-i '/media/julien/USBKEY/capture_%d/%d/*.jpg' \
-r 5 -c:v libx264 -pix_fmt yuv420p \
/media/julien/USBKEY/capture_%s/%d/out%d.mp4 -y
另请参阅示例这里。
对于您的程序代码，我建议使用 Python 格式字符串并利用模块subprocess而不是直接调用system：
import subprocess
subprocess.check_output(
f"ffmpeg -y -f image2 -framerate 1 -pattern_type glob -start_number {nom_premiere_image} -i '/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/*.jpg' -r 5 -c:v libx264 -pix_fmt yuv420p /media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/out{nom_sous_dossier}.mp4", shell=True
)
更好的是，将命令中的所有内容放入列表中并传递：
subprocess.check_output([
"ffmpeg", "-y", "-f", "image2", "-framerate", "1", "-pattern_type", "glob", "-start_number", nom_premiere_image,
"-i", f"'/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/*.jpg'",
"-r", "5", "-c:v", "libx264", "-pix_fmt", "yuv420p",
f"/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/out{nom_sous_dossier}.mp4",
])
