FFmpeg 在遇到坏图像文件后停止将图像编码为视频

我使用 Raspberry Pi 通过多路复用器同时从 2 个摄像头录制，这意味着我无法将其设置为直接录制 mp4，而是必须拍摄图像、切换摄像头，然后再拍摄另一张图像，然后将其转换为 mp4。有时它会拍摄损坏且无法读取的不良 jpg，我曾尝试找到解决方法，但似乎找不到一致拍照的方法，而且无论如何，跳帧也不是世界末日。

问题是，当我使用 FFmpeg 将这些图像转换为视频时，坏帧会导致它在帧之前过早停止。它没有出错，只是停止了。如果有一个标志可以跳过坏帧并继续编码视频的其余部分，那就太完美了。

我尝试使用：-err_detect active -fflags discardcorrupt 更改输入和输出帧速率

这是我正在使用的命令： ffmpeg -framerate 1 -err_detect aggressive -fflags discardcorrupt -i recordings/current-recording/CameraA/%05d.jpg CameraA.mp4

以下是它在控制台中产生的效果：
