最近，我一直在尝试修改一个小机器人的引导动画。它是一个.raw文件，包含一个接一个的每个RGB565帧。我已经能够使用获得所有的帧
ffmpeg -f rawvideo -pixel_format rgb565 -video_size 184x96 -framerate 10 -i "boot_anim.raw" -r 1/1 boot_anim%02d.png
但如果我试着用重新包装
ffmpeg -i boot_anim%02d.png -f rawvideo -pix_fmt rgb565 -framerate 10 -video_size 184x96 -r 1/1 "boot_anim.raw"
它只放入前两帧，没有其他内容。我还尝试过libx264和手动放入vcodec。同样的结果。我是ffmpeg和Linux的新手。
以下是完整输出：

感谢您的帮助！
想明白了。我只需要添加vsync 0。
