MP4 container doesn't support WMA, so converting container from your WMV video to MP4 isn't possible without transcoding the audio

From your log:
[mp4 @ 0x73cc040] Could not find tag for codec wmapro in stream #0, codec not currently supported in container

For reference and codec/container compatibility see: https://en.wikipedia.org/wiki/Comparison_of_video_container_formats
Note: WMV video is in an ASF container

[mifi]

Yea, see https://github.com/mifi/lossless-cut#re-encode-only-the-audio-track-keeping-the-lossless-video-track

I want losslesscut to give some kind of warning when trying to do this. Closing in favor of #547

[aanishacharyaa]

@mifi If when I followed https://github.com/mifi/lossless-cut#re-encode-only-the-audio-track-keeping-the-lossless-video-track it says "Track 0 mismatch: codec_name mp3 != wmv1"

[mifi]

@aanishacharyaa Whoops I think those instructions are wrong! Merge is not the right tool to use. Instead open the mp3 audio file you just created and select "Include all tracks from the new file". I will update Readme
