[Request] Automatically install ffms2

[moi15moi]

It would be nice if when we install this tool, it could also install ffms2.

It make it user friendly and when a another program need this tool, it does not need to ask the user to install ffms2 by themself.

@rr- Is there any problem with my request?

Hi, I am interested in this feature as well!
To specify, I think that a "local" installation of ffms2 is preferable (so, have a version of ffms2 inside the library folder), as users may have their own ffms2 already installed somewhere else.

Hi, sorry for the late reply! Yeah, it is a good request, but currently I don't have time to implement it, PRs accepted though!

I won't do it.
I already have try locally, but I can't do nothing work really well.

But, here is what I did to download the latest ffms2 releases:

import ffms2
import json
import os
import re
import requests
import struct
from pyunpack import Archive

# Get ffms2 download url
ffms2Url = requests.get('https://api.github.com/repos/FFMS/ffms2/releases/latest')
ffms2Json = json.loads(ffms2Url.text)
ffms2UrlDownload = ffms2Json["assets"][0]["browser_download_url"]

# Download ffms2
response = requests.get(ffms2UrlDownload)
fname = re.findall("filename=(.+)", response.headers['content-disposition'])[0]
open(fname, "wb").write(response.content)

# Extract ffms2
Archive(fname).extractall(".")

# Get directory where ffms2.dll, ffms2.lib and ffmsindex.exe are
cpuArchitecture = "x64" if struct.calcsize("P")*8 == 64 else "x86"
ffms2Files = "./" + os.path.splitext(fname)[0] + "/" + cpuArchitecture # won't work with posix path

# Copy ffms2 files to pyffms2 directory
fileNames = os.listdir(ffms2Files)
for fileName in fileNames:
    shutil.move(os.path.join(ffms2Files, fileName), os.path.dirname((ffms2.__file__)))

PS, it need these two dependancy to unzip the file

pip install pyunpack
pip install patool
