| 3 | +Google Cloud Video Intelligence API Python Samples |
| 4 | +=============================================================================== |
| 5 | + |
| 6 | +This directory contains samples for Google Cloud Video Intelligence API. `Google Cloud Video Intelligence API`_ allows developers to easily integrate feature detection in video. |

| 13 | +Setup |
| 14 | +------------------------------------------------------------------------------- |
| 15 | + |
| 16 | + |
| 17 | +Authentication |
| 18 | +++++++++++++++ |
| 19 | + |
| 20 | +Authentication is typically done through `Application Default Credentials`_, |
| 21 | +which means you do not have to change the code to authenticate as long as |
| 22 | +your environment has credentials. You have a few options for setting up |
| 23 | +authentication: |
| 24 | + |
| 25 | +#. When running locally, use the `Google Cloud SDK`_ |
| 26 | + |
| 27 | + .. code-block:: bash |
| 28 | +
|
| 29 | + gcloud auth application-default login |
| 30 | +
|
| 31 | +
|
| 32 | +#. When running on App Engine or Compute Engine, credentials are already |
| 33 | + set-up. However, you may need to configure your Compute Engine instance |
| 34 | + with `additional scopes`_. |
| 35 | + |
| 36 | +#. You can create a `Service Account key file`_. This file can be used to |
| 37 | + authenticate to Google Cloud Platform services from any environment. To use |
| 38 | + the file, set the ``GOOGLE_APPLICATION_CREDENTIALS`` environment variable to |
| 39 | + the path to the key file, for example: |
| 40 | + |
| 41 | + .. code-block:: bash |
| 42 | +
|
| 43 | + export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service_account.json |

| 49 | +Install Dependencies |
| 50 | +++++++++++++++++++++ |
| 51 | + |
| 52 | +#. Install `pip`_ and `virtualenv`_ if you do not already have them. |
| 53 | + |
| 54 | +#. Create a virtualenv. Samples are compatible with Python 2.7 and 3.4+. |
| 55 | + |
| 56 | + .. code-block:: bash |
| 57 | +
|
| 58 | + $ virtualenv env |
| 59 | + $ source env/bin/activate |
| 60 | +
|
| 61 | +#. Install the dependencies needed to run the samples. |
| 62 | + |
| 63 | + .. code-block:: bash |
| 64 | +
|
| 65 | + $ pip install -r requirements.txt |
| 66 | +

| 73 | +analyze |
| 74 | ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ |
| 75 | + |
| 76 | + |
| 77 | + |
| 78 | +To run this sample: |
| 79 | + |
| 80 | +.. code-block:: bash |
| 81 | +
|
| 82 | + $ python analyze.py |
| 83 | +
|
| 84 | + usage: analyze.py [-h] {faces,labels,labels_file,safe_search,shots} ... |
| 85 | + |
| 86 | + This application demonstrates face detection, label detection, safe search, |
| 87 | + and shot change detection using the Google Cloud API. |
| 88 | + |
| 89 | + Usage Examples: |
| 90 | + |
| 91 | + python analyze.py faces gs://cloudmleap/video/next/volleyball_court.mp4 |
| 92 | + python analyze.py labels gs://cloudmleap/video/next/fox-snatched.mp4 |
| 93 | + python analyze.py labels_file resources/fox-snatched.mp4 |
| 94 | + python analyze.py shots gs://cloudmleap/video/next/gbikes_dinosaur.mp4 |
| 95 | + python analyze.py safe_search gs://cloudmleap/video/next/animals.mp4 |
| 96 | + |
| 97 | + positional arguments: |
| 98 | + {faces,labels,labels_file,safe_search,shots} |
| 99 | + faces Detects faces given a GCS path. |
| 100 | + labels Detects labels given a GCS path. |
| 101 | + labels_file Detects labels given a file path. |
| 102 | + safe_search Detects safe search features the GCS path to a video. |
| 103 | + shots Detects camera shot changes. |
| 104 | + |
| 105 | + optional arguments: |
