Issue
- Some MP4 videos are not functioning correctly.
-
Steps to Reproduce:
1) Startup Liferay 7.3 SP1
2) Install Xuggler.
3) Upload some MP4 videos
Expected Behavior: All the videos should be played.
Observed Behavior: While some videos are playing, others are not.
Resolution
- The observed behavior is a known DXP issue. The issue comes from Xuggler, a third-party library used to generate video previews.
- However, since Xuggler fails to encode these videos, this issue cannot be addressed at the Liferay code level. However, on DXP 7.4, FFMPEG could generate the preview for these videos using the other preview generator.
- As a result, the workaround can be:
(I) Try to convert or fix the videos: since the issue has been recorded with just a few videos, not all of them, try to create the videos in the same format or size as the ones they can play, since which videos it can encode is a limitation from Xuggler.
(II) Try to update to DXP 7.4, since the videos worked fine on that version.
