Summary
Some video files are not working with the Multimedia Macro, while other Pages have videos that are working fine.
Environment
Confluence 7
Diagnosis
- Create a new Page.
- Attach a video file.
- Include the Multimedia Macro and select the attached video.
- Save the Page.
- Check the results.
Expected outcome: the video plays just fine like in other Confluence Pages.
Actual result: the video fails to be reproduced.
Cause
The Multimedia Macro uses HTML5 video, so the type of video your Page viewers can see depends on the video formats their browser supports with the HTML5 <video> tag.
For the most widespread browser support, we recommend using MP4 files with the H.264 codec as it is supported by all major web browsers.
Please note that other video formats and codecs may also work, but that depends entirely on the client's web browser support.
Reference: HTML5 video: Browser support.
Solution
Solution 1 (Recommended) - Convert the video that is not working with the Multimedia Macro to a supported video format and codec (eg.: MP4 and H.264) and re-upload it.
Solution 2 - Switch to a browser that supports the video format and codec used to export / compress the video.
