Error Converting Video Without Audio

[PapaNinjago]

Hello,

I am trying to convert a WMV file to MP4. The WMV file does not have audio. When I tried to convert using MP4 (copy, no encoding) with Audio Stream: Copy 1:1 From Source, the following appears:

Error converting to MP4 (copy, no encoding), 'C:\Temp\Video.wmv' to 'C:\Temp\Video.mp4'
[mp4 @ 0000000000f5d480] Could not find tag for codec wmv1 in stream *0, codec not currently supported in container
Could not write header for output file *0 (incorrect codec parameters ?): Invalid argument

It is likely nothing to do with the audio, more likely the wma file. Can you play it? is it protected?

I am able to play the WMV file without issue.
