Python video metadata parser
License: MIT License
Enzyme is a Python module to parse video metadata.
Parse a MKV file metadata:
>>> import enzyme
>>> with open('example.mkv', 'rb') as f:
... mkv = enzyme.MKV(f)
...
>>> mkv.info
<Info [title=None, duration=0:00:01.440000, date=2015-03-14 08:40:16]>
>>> mkv.video_tracks
[<VideoTrack [2, 720x576, V_DIRAC, name=u'Video\x00', language=None]>]
>>> mkv.audio_tracks
[<AudioTrack [1, 2 channel(s), 44100Hz, A_MS/ACM, name=u'Audio\x00', language=None]>]Enzyme is licensed under the MIT license.

Any clue?

from pkg_resources import resource_stream in parsers/ebml/core.py makes the package depend on setuptools, which is currently not reflected in the package metadata
VideoTrack should have bit_depth property as AudioTrack does:
The field is quite important to differentiate 8 bit videos from 10 bit videos

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.
It would be nice to be able to write metadata to files, and not only reading them.
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?
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:
American Horror Story - S05E01 - Checking In (Bluray-1080p - x264 DTS [EN+FR+DE+JA+ES]).mkv {'forced': False, 'name': None, 'language': None, 'default': False, 'enabled': True, 'number': 3, 'codec_name': None, 'codec_id': u'S_HDMV/PGS', 'lacing': False, 'type': 17} {'forced': False, 'name': None, 'language': u'fre', 'default': False, 'enabled': True, 'number': 4, 'codec_name': None, 'codec_id': u'S_HDMV/PGS', 'lacing': False, 'type': 17} {'forced': False, 'name': None, 'language': u'ger', 'default': False, 'enabled': True, 'number': 5, 'codec_name': None, 'codec_id': u'S_HDMV/PGS', 'lacing': False, 'type': 17} {'forced': False, 'name': None, 'language': u'jpn', 'default': False, 'enabled': True, 'number': 6, 'codec_name': None, 'codec_id': u'S_HDMV/PGS', 'lacing': False, 'type': 17} {'forced': False, 'name': None, 'language': u'spa', 'default': False, 'enabled': True, 'number': 7, 'codec_name': None, 'codec_id': u'S_HDMV/PGS', 'lacing': False, 'type': 17}
Any help with getting this fixed would be fantastic :)
