FFMPEG Error VC1 to X264 (maybe decoding VC1)

Question

I am encountering the following error when transcoding using FFMPEG. It seams to me that it's an error decoding the VC1 format and has actually nothing to do with the target format (x264) I want to transcode.

I tracked the error to this source-file:

http://cekirdek.pardus.org.tr/~ismail/ffmpeg-docs/vc1_8c-source.html

but I don't know how to set the profile to a value != simple.

FFMPEG Output:

test.vc1: could not find codec parameters

Here is the CMD-line i use ... xD Basically I stripped EVERYTHING (codec-related and quality-related) because the error happens no matter what I pass ...

ffmpeg -i test.vc1 test.mkv

Answer 1

I actually solved this problem by moving the raw VC1-stream into a container before passing it to ffmpeg. I used mkv but I assume some other container might work as well ...

Command-Line:

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