我正在尝试将 mov 视频转换为 flv，但在下面不断出现这些错误。我使用了 2 个命令，都在下面。
ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

第二条命令：
ffmpeg -y -i video.mov -deinterlace -ar 44100 -r 25 -qmin 3 -qmax 6 video.flv
音频重采样器仅适用于每个样本 16 位，欢迎使用补丁。

请再做一件事：如果我使用这个较新版本的 ffmpeg 使用以下命令创建视频，我会得到一个显示非常模糊的视频。这就像一个空白屏幕上的几个黑点：
ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov
这种显示的原因可能是什么？
