Implementation Brief

@injainja many thanks for reporting! I can see the issue in the Firefox browser with the video in your first story page.

There may be something specific with the video in the first story page that is preventing the audio from playing in Firefox.

• Audio is not available when I visit the mp4 media file URL to the video in Firefox directly. When I visit the link in other browsers it plays without issue.
• Additionally, the second video's media file URL plays audio in Firefox and other browsers without issue.

Could you check and let me know if you experience the same?

[injainja]

Yes - the problem seems to be caused by the video and not by the plugin. So you can close this topic. Thank you so much, I will try to find the cause of the problem and will post it here in case someone else runs into the same problem.

JFYI - I found the problem. Mozilla doesn't like videos with 192 / mp3 Audio. Changed it to 128 / AAC and it works now. Thanks to @ernee for pointing me in the right direction. I really appreciate your work, guys! The plugin is going to be awesome and very, very helpful for a lot of people. Web-Stories are the future of the web imho.
