M2TS video file is not accepted

[KatieBelli]

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with a different kind of file to confirm that the problem is related to just this file.
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions

Steps to reproduce

Import a m2ts video file into Lossless Cut GUI.

Expected behavior

It should load the video file like any other video file so you can edit and export it like usual.

Actual behavior

It suggests that I should convert it to another format and it doesn't play the video.

Errors:
"File not natively supported. Preview may have no audio or low quality. The final export will however be lossless with audio. You may convert it from the menu for a better preview with audio."

"Unable to playback this file. Try to convert to supported format from the menu."

Provide an error report

No error occurred.

where did you get this file from? seems to have a quite old codec SMPTE VC-1 (Microsoft WMV) https://en.wikipedia.org/wiki/VC-1

I tested the file Test_1440x576_WVC1_6Mbps.wmv from https://samples.mplayerhq.hu/V-codecs/WVC1/ and it works for me. Does it work if you convert it to a supported format first? select for example output format matroska. see also faq: https://github.com/mifi/lossless-cut/blob/master/issues.md
