Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Is the HAP video codec supported on Windows?

I've been trying to get a video with HAP video codec (and alpha channel) to work with the Unreal MediaPlayer (on Windows), but I only get a black screen. Preview in MediaPlayer is black too.

So is this codec currently supported in Unreal? If so, how do I get a video with this codec and with alpha channel working?

Video file is a .mov file.

Product Version: UE 4.13

We do not currently have a player plug-in that supports HAP. If nobody in the community makes one, I may implement one next year, but it won't happen before April 2017 at the earliest.

Just thought id poke on this since its something that would be incredibly useful for a project I am developing. Im not super savvy with global shaders and such so implementing by myself is an intimidating task. Are you still interested in doing this as there has been no other movement?

Hi @gmpresussner,

Any update on HAP support in Unreal Engine?

No update, and it's not on the roadmap right now, sorry.

I don't know if this applies to what you are trying to do, but if you don't mind using a 3rd party you could play a HAP video with Lightact media server and then transfer the texture to UE4 using Spout (and this plugin). Once inside UE4, you can apply it as a material directly or use the texture inside the material editor.
