我想将几张照片（.jpg或.png）与电影（主要在.mp4）合并并将最终输出存储为电影（在.mp4）
期间
照片默认时长 - 6 秒
默认视频时长 - 无变化（与原始文件一样）
声音
照片上没有声音。
视频 - 原声（与原始文件相同）
第一人称射击游戏
照片的FPS ( framerate) 并不重要。我知道最低值是6。对我来说可以是6或24。视频的 FPS 应该保持原样（不做任何更改）。
所有文件的大小可以不同（例如，500x100++ 1024+2028）360x480。我认为输出应该以某种方式统一（例如，1920×1080拉伸其余文件但调整比例）

我也尝试过：
- 有还是没有
-r 24 - 有还是没有
movflags - 与不同
-preset的 - 与不同
-crf的
但效果是一样的。
结果
视频已创建（具有适当的尺寸、比例和持续时间）。
我可以在默认（本机）或外部 Android 视频播放器（例如 VLC）中播放视频。
例如，我无法分享到 Instagram — — 它不起作用。

合并工作正常。所有元素的长度都正确。但主要问题是电影底部闪烁着“绿色”（有时是“粉红色”）（几乎存在于整个电影中，高度始终相同）
以及如何使照片保持静音但保留视频的声音。
