我试图制作少数幻灯片视频（在本例中为3）.jpgs。要做到这一点，我使用
ffmpeg -r 1/5 -i bat%03d.jpg -c:v libx264 -r 30 -pix_fmt yuv420p proba12.mp4
实际上它适用于Windows（它播放每个图像5秒）但是在raspbian上它既不能用于omxplayer也不能用于hello_video.bin（在h264中）。
以下是控制台显示的内容：

如果我试图使用文本文件连接这些文件并且我将每个文件的持续时间设置为5会产生不同的显示时间，这也很奇怪...在这个例子中，第一个显示15秒，第二个显示5秒，最后一个10秒......当然这种合并图像的方式在raspbian下也不起作用
我使用Rasberry pi 3b和最新的raspoped noobs在船上
你能指导我一个解决方案吗？我的想法很快......干杯
