Today, we’re rolling out a quality of life improvement to Gmail desktop users that makes previewing video attachments in Gmail much smoother and quicker. Previously, in order to view a video attachment in Gmail, you would have to download it to your computer and open it with a media player. Starting today, when opening an email with video attachments, you will see a thumbnail of the video and have the ability to stream it, right from inside Gmail.
This feature uses the same Google infrastructure that powers YouTube, Google Drive, and other video streaming apps, so video is delivered at optimal quality and availability. If you have apps that would also benefit from integrating video streaming, check out Google Cloud Platform Media Solutions.
