Question

使用FFMPEG进行转码时遇到以下错误。我联系到它解码VC1格式时出错，实际上与我想要转码的目标格式（x264）无关。

我跟踪了这个源文件的错误：

但我不知道如何将配置文件设置为值！=简单。

FFMPEG输出：

这是我使用的CMD线...... xD 基本上我剥离了一切（编解码器相关和质量相关）因为无论我通过什么错误都会发生......

ffmpeg -i test.vc1 test.mkv

Answer 1

我实际上是通过将原始VC1流转移到容器中然后将其传递给ffmpeg来解决这个问题。我使用mkv，但我认为其他一些容器也可以正常工作......

命令行：

mkvmerge -o temp.mkv source.vc1
ffmpeg -i temp.mkv output.mkv

此致

FFMPEG错误VC1到X264（可能解码VC1）

FFMPEG输出：
