I'm encountering the following error when scanning a specific mkv file with subliminal 0.8.0 (had same issue with 0.7.3). It works fine with other mkv files.
Any clue?

I assumed the output of mkv.tags was a python dictionary and tried to convert to json without success. The output is not json. XML conversion failed too.
What is the output format?
Setuptools allows this.

From the GitHub repo description (Python video metadata parser) and the README, I thought this could parse many different kinds of video formats.
Unfortunately, it looks to me like it only supports Matroska. (Which is a great format! But many others exist…)
Please update the description and the README so others don’t get fooled like I was.
I use enzyme-0.4.2.dev0 to get mp4 video file metadata, and there was an error:

MemoryError
I am having trouble with enzyme detecting the first(or maybe just english?) embedded subtitle language. This seems to be happening with all of my files so is it somehow possible that this is a result of something in my setup? I originally reported this as a bug with nzbget-subliminal but @caronc has helped me realise the actual problem lies with enzyme here. Apologies, but I am not sure how to get further debugging information from enzyme to help.
An example file I am talking about is: Game.of.Thrones.S05E01.The.Wars.to.Come.1080p.WEB-DL.DD5.1.H.264-NTb
ffprobe output: https://pastebin.com/iQVU4whX
mediainfo output: https://pastebin.com/BtUNSRjf
but the enzyme output is:
python test.py /home/matt/subliminal_test/Game.of.Thrones.S05E01.The.Wars.to.Come.1080p.WEB-DL.DD5.1.H.264-NTb.mkv /home/matt/subliminal_test/Game.of.Thrones.S05E01.The.Wars.to.Come.1080p.WEB-DL.DD5.1.H.264-NTb.mkv {'forced': False, 'name': None, 'language': None, 'default': False, 'enabled': True, 'number': 3, 'codec_name': None, 'codec_id': u'S_TEXT/UTF8', 'lacing': False, 'type': 17}
Another example is:
mediainfo output: https://pastebin.com/xS7B4L78
ffprobe output: https://pastebin.com/69bCLQ75
enzyme output is:

Any help with getting this fixed would be fantastic :)
It would be nice to be able to write metadata to files, and not only reading them.
