USAGE https://docs.google.com/document/d/1vI_1rxZa0yYsjjiVUBoUlwoH_j7AanGDvSsMvNhx5Gk/edit INSTALLATION This script is for extracting and transcribing audio files from .mp4 video files into .srt formatted text files for subtitling purposes using Googles Speech-to-Text and Google Cloud Storage APIs. It outputs both a raw text transcription and a .srt formatted version. In the current version, this script requires you to authenticate your Google credentials through the gcloud CLI and also requires that you have ffmpeg installed locally on your machine (for video to audio conversion and compression) Instructions for use Use the Cloud Platform Console to create a new Cloud Platform project, create an App Engine application, and enable billing: https://console.cloud.google.com/ (Skip if project already set up) Enable the Google Speech to Text API in APIs and Services in new project dashboard Set up a storage bucket in Google Cloud Storage Download, install and set up Google SDK https://cloud.google.com/sdk/ (authenticate your machine by following the auth instructions) On OSX make sure you have brew (install from https://brew.sh/ if not) Install ffmpeg brew update brew install ffmpeg --with-opus To install with all options: http://www.renevolution.com/ffmpeg/2013/03/16/how-to-install-ffmpeg-on-mac-os-x.html Set your virtual environment If you don't have virtualenv, install it using pip. OSX: sudo easy_install pip sudo pip install virtualenv Create an isolated Python environment, and install dependencies: virtualenv env source env/bin/activate pip install -r requirements.txt In goog.py change the bucket_name variable to the name of the storage bucket you wish to use To run transcription script add .mp4 files to a specified directory Then run: python auto_run.py /path/to/directory/ The script will automatically strip the audio files from the video and convert them to .ogg format The it uploads the audio to the gcloud storage bucket and then passes its gcs_uri to the speech to text API for processing When finished, it outputs both the .srt formatted file and raw text file into the specified directory Note that if the program errors, it terminates as to not potentially abuse any API quota limits
