インストール方法
※pipenvはあらかじめインストールしておきます。sudo apt-get update
sudo apt-get -y install mediainfo libjpeg-dev
pipenv install pymediainfo
サンプルプログラム
ファイル中のトラックから、コーデックの種類や解像度などの情報を一覧表示します。mi.py
from pymediainfo import MediaInfo
mi = MediaInfo.parse("/home/debian/hydrangea.mp4")
for track in mi.tracks:
print("--------------------------")
for mykey, myvalue in track.to_data().items():
print("key: {}, value:{}".format(mykey, myvalue))
実行例
pipenv run python mi.py
