Can't display MJPEG stream

[helldog136]

Hi,

I'm trying to display a MJPEG stream served via http using VLC in an Unreal Engine 4.18 app. But when i open the StreamMediaSource with a Media Player i get the following error:

LogVlcMedia: Error: mmdevice: cannot initialize COM (error 0x80010106)
LogVlcMedia: Error: vmem: video format setup failure (no pictures)
LogVlcMedia: Error: main: video output creation failed
LogVlcMedia: Error: main: failed to create video output
LogVlcMedia: Error: vmem: video format setup failure (no pictures)
LogVlcMedia: Error: main: video output creation failed
LogVlcMedia: Error: main: failed to create video output
LogVlcMedia: Error: main: Failed to set on top
LogVlcMedia: Warning: avcodec: plane 0 not aligned: disabling direct rendering

The media seems to be playing (ie the time counter is active) but the image stays black.

On the other hand, i am able to open and dispay the stream outside of UE4 using VLC

What did i do wrong?

Did you fix the problem? Please help me if is. I spend two days on it and still in research.

Hi, this is very old and I can't remember how I did it...
