FFMPEG 错误 VC1 到 X264(可能解码 VC1)

Question

使用 FFMPEG 进行转码时遇到以下错误。
在我看来，这是解码 VC1 格式的错误，实际上与我要转码的目标格式 (x264) 无关。
我跟踪到这个源文件的错误:

但我不知道如何将配置文件设置为一个值!=简单。
FFMPEG 输出:

这是我使用的 CMD 行... xD
基本上我剥离了一切(与编解码器相关和与质量相关)，因为无论我通过什么都会发生错误......

ffmpeg -i test.vc1 test.mkv

Answer 1

实际上，我通过在将原始 VC1-stream 传递给 ffmpeg 之前将其移动到容器中来解决了这个问题。
我使用了 mkv，但我认为其他一些容器也可以工作......

命令行:

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