    What codec works? Im using Mpeg-4 in a .mp4 with noooo luck
    For me, WMV works. Tried other formats as well without luck.
    But WMV is ok. Once its on the screen, you cant taste the difference

        No luck on my end with wmv. Works in Editor, not while built

            Wow- very excited to see this feature.

            Seriously, you guys just need to implement some kind of animated vertex cache (like alembic, not just morph targets) and I doubt the competition will "Ryse" to the challenge.
            Very impressed with how in the loop the UE4 team has kept its subscribers. I was a beta tester for another engine and had no idea what was going on half of the time. Good stuff!

              I still can't seem to get things going with wmv files... Has anyone? Can someone maybe upload their wmv that works to see if its my media? Is there any codec pack that needs to be installed?

                Same issue with me, works in Editor but the texture is white after the project is built. I can see the media files in the BuildProjectName/Content/Movies dir though after building.

                Using wmv here since it's documented to be working without problems on Windows.

                Any suggestions?

                  Same issue here. The .wmv movie is playing fine in the editor and when I play. However, texture remains white when I launch.

                  I am currently trying to get access to the movie player from the level blueprint to trigger playback.

                            Alpha channels/transparency

                            Do we have support for alpha channels or does transparency work in a similar way to UE3 where you could run a alpha video in the opacity node to get transparency?
                            That would be super helpful for me also! Has anybody figured this out?

                              Sorry for the delay, guys - this was a tough one to figure out. Turns out that the handling of relative paths for movie files was incorrect for staged builds, and we also launched the wrong binary on Windows. There is now a fix for this in the master branch: https://github.com/EpicGames/UnrealE...1f41eafcdf9cf0

                              Unfortunately, this fix did not make it into the 4.5 release. It will have to go into the next hotfix instead.

                              That being said, even in 4.5, media playback should work in the following scenarios:
                              - "Package Project..." in the Editor's File menu
                              - "Launch" in Editor viewport
                              - "Launch" in Standalone game
                              - "Launch" on device for any platform other than Windows and MacOS

                              Please let me know if you experience any other issues, thanks!


                              PS: after syncing to the fix on Github you need to reset the "URL" field in your MediaPlayer assets. Movie files must still be located inside /YourProject/Content/Movies/ for now.

                                Thanks for all the hard work. I do have a question, though:

                                I just downloaded the 4.5 Content Examples. Am I just blind, or is there no TestMaps folder?

                                The description above says:
                                "The ContentExample sample project now actually contains a demo level that implements an entire media player using UMG. The name of this level is UnrealMotionGraphics, which is currently located inside the project’s /Content/Maps/TestMaps/"

                                I'd love to have a look at those. Where can I find them?
