Hello,
I’m using UE4.13.2 for a project that needs to run on Ubuntu. The project needs to be able to play videos. To achieve this, I’ve added the 3rd-party plugin that wraps Vlc 3:
Now, I’ve added lots of logging to Unreal and the Plugin, and it looks like:
- Vlc and its libraries are being found and instantiated
- The target videos I’m using to test are being found when running on
Ubuntu - Vlc/Plugin are reporting no errors and a status of “Playing”. (*
“Playing” reappears after the video
finishes playing as it loops, and
given the timing of when it
reappears, it does in fact seem to be
correct). - I used Editor to “auto create” the material/texture like all the various
tutorials show for other video
players - The video path is relative, and is present when deployed.
- The test videos being used do play with the same standalone Vlc player
on Ubuntu, so the codecs/plugins seem
okay. - The video player for the various videos is set to Vlc in the Editor,
and from the logging I’ve added, it
is being used. - I’ve dragged the auto-created material/texture onto a plane (that
has UVs) in the test level, which
itself successfully shows on Windows in-Editor.
The reason I’ve posted a question here is from the various logging/debugging I’ve done (including with “strace” which seems to be Ubuntu’s “filemon” equivelent) is all the parts from Vlc/Ubuntu through to the level appear to be fine. The video seems to be playing, but it’s just not visible - the plane stays black/gray.
The same code successfully plays the videos in-Editor and Editor-standalone.
Question is: How do I debug why the material/texture isn’t showing the apparently ‘playing’ video, JUST on Linux when there appears to be no errors anywhere else? How do I debug this?
Many thanks!
