Question

我正在尝试将mov视频转换为flv，但仍然会在下面收到这些错误。我使用了2个命令，两个命令都在下面。

ffmpeg -y -i video.mov -deinterlace -acodec copy -r 25 -qmin 3 -qmax 6 video.flv

第二个命令：

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。

请再说一件事：如果我使用这个较新版本的ffmpeg使用以下命令创建视频，我会得到一个非常模糊的视频。这就像空白屏幕上的几个黑点：

ffmpeg -i img%d.png -i audio.wav -acodec copy output.mov

这可能是什么原因？

Answer 1

你可以试试这个简单的：

ffmpeg -y -i video.mov video.flv

在第一个命令中，音频编解码器为pcm_u8，与flv不兼容。由于您使用了-acodec copy，因此会导致错误。在第二个命令中，重新采样导致问题。

ffmpeg将mov转换为flv
