"""h264ify - Upgrade my videos to h.264/AAC for Chromecast.
|
|
|
|
With Google Chrome, you can Chromecast any movie file from your PC by dragging
|
|
the movie into a Chrome window, and then cast the tab to your Chromecast.
|
|
|
|
However this only works if the video is encoded with H.264 for video and
|
|
AAC for audio. Other video files will instead "download" in Chrome instead of
|
|
play inside the tab.
|
|
|
|
This script takes input video file names (without a `.mp4` extension), and
|
|
encodes them into a file of the same name but with a `.mp4` extension.
|
|
|
|
Usage: h264ify <video files...>
