Hello,
I cannot figure out how to use the new HAP codec. I would like to work with rgb+a video in UE4 4.23.1. I enabled the Plugin and restarted. I get an instant crash the moment UE attempts to decode the video (see crash output below). I am using the latest version of ffmpeg to generate the HAP videos using the .mov container. I have tried HAP, HAP Alpha, and HAP Q, all of them insta-crash. The resolution is only 720x540, and I am not using an audio track or embedded timecode as per the documentation. I am running on windows 10, and a GTX 1080 gpu (if that matters?). All of the videos playback in VLC media player without any issues. I feel the documentation regarding the HAP codec is extremely light. If anyone has any experience I would love to hear how you got it to work?
I haven’t tried yet but plan to try exactly the same process (ffmpeg for encoding, w10, even running on a 1080!)
I thought I would do a bit of googling first, as you’re right it’s low on documentation (though according to this which you’ve probably read, it sounds possible), Media Framework Technical Reference | Unreal Engine Documentation. And I came across your post while searching.
I’m hoping you can tell me if you got any further?
If not I will attempt it early next week and post my findings here (if you haven’t already) to spread the know how!
Hello guys,
I have another issue about HAP playback.
I can play them in Unreal Media Player, but colors are more exposed.
If I open the original and the HAP file in other players like Quicktime, After Effects, VLC, etc they are correct.
In Unreal looks like a wrong color interpretation.
