Does not worth with mkv video files #110

Open Spedwards opened 1 year ago

Spedwards commented 1 year ago

I've been using vcsi for a while and always with mp4 files. I recently switched to using mkv files and immediately noticed that vcsi does not work with them at all. I converted one of these files to an mp4 (not changing codecs or anything) and it worked.

Here's the ffprobe output of a short mkv file I tested with:

Here's the ffprobe output for the same file after converted to mp4:

That mp4 output has an error and still vcsi works on it.

I just started using vcsi, using some MKVs from last year to get set up and it works fine for me:
