I’m currently using Unreal 4.17 on Windows 10, but I believe I had the same issue in 4.16. I have tried many different video files - mp4, wmv, different framerates, etc, and every single one says seeking is not supported. It seems like such a simple thing, but I have gotten nowhere with it. Checking “Supports seeking” node always returns false, attempting to seek anyway always fails, and the info in the media player reports “Seeking: No”
Well I tried messing with seek again tonight, and it’s working now! I have no idea what’s different or why it decided to start working, so unfortunately I can’t offer any assistance to anyone else that has these issues. I am still using an h.264 encoded mp4 file.
