+
+
+This directory contains samples for Google Cloud Video Intelligence API. `Google Cloud Video Intelligence API`_ allows developers to easily integrate feature detection in video.
+
+
+
+
+.. _Google Cloud Video Intelligence API: https://cloud.google.com/video-intelligence/docs
+
+
+Setup
+-------------------------------------------------------------------------------
+
+
+
+Authentication
+++++++++++++++
+
+This sample requires you to have authentication setup. Refer to the
+`Authentication Getting Started Guide`_ for instructions on setting up
+credentials for applications.
+
+.. _Authentication Getting Started Guide:
+    https://cloud.google.com/docs/authentication/getting-started
+
+
+
+
+Install Dependencies
+++++++++++++++++++++
+
+#. Clone python-docs-samples and change directory to the sample directory you want to use.
+
+    .. code-block:: bash
+
+        $ git clone https://github.com/GoogleCloudPlatform/python-docs-samples.git
+
+#. Install `pip`_ and `virtualenv`_ if you do not already have them. You may want to refer to the `Python Development Environment Setup Guide`_ for Google Cloud Platform for instructions.
+
+   .. _Python Development Environment Setup Guide:
+       https://cloud.google.com/python/setup
+
+#. Create a virtualenv. Samples are compatible with Python 3.6+.
+
+    .. code-block:: bash
+
+        $ virtualenv env
+        $ source env/bin/activate
+
+#. Install the dependencies needed to run the samples.
+
+    .. code-block:: bash
+
+        $ pip install -r requirements.txt
+
+.. _pip: https://pip.pypa.io/
+.. _virtualenv: https://virtualenv.pypa.io/

+
+
+
+
+To run this sample:
+
+.. code-block:: bash
+
+    $ python labels.py
+
+
+    usage: labels.py [-h] path
+
+    This application demonstrates how to detect labels from a video
+    based on the image content with the Google Cloud Video Intelligence
+    API.
+
+    For more information, check out the documentation at
+    https://cloud.google.com/videointelligence/docs.
+
+    Usage Example:
+
+        python labels.py gs://cloud-ml-sandbox/video/chicago.mp4
+
+    positional arguments:
+      path        GCS file path for label detection.
+
+    optional arguments:
+      -h, --help  show this help message and exit
+
+
+
+
+
+
+
+
+
+The client library
+-------------------------------------------------------------------------------
+
+This sample uses the `Google Cloud Client Library for Python`_.
+You can read the documentation for more details on API usage and use GitHub
+to `browse the source`_ and  `report issues`_.
+
+.. _Google Cloud Client Library for Python:
+    https://googlecloudplatform.github.io/google-cloud-python/
