Winforms VideoView not playing video on Ubuntu18.04 with mono.

Hello! My goal is to make a Winforms form that opens an .mp4 video located on my PC. For that I'm using LibVLCSharp.Winforms and I run it with Mono 6.0.0 on Ubuntu 18.04.

The problem is when I call Play() on a MediaPlayer object, the video opens in a new window and everything looks fine, but when I call Play() on a MediaPlayer of VideoView that's embedded in a Winforms form, then the audio plays normally, but there's no video showing at all and the output looks as follows:

[00007f1774074ce0] main video output error: video output creation failed

[00007f178c0d1170] main decoder error: failed to create video output

[h264 @ 0x7f178c0e4540] get_buffer() failed

[h264 @ 0x7f178c0e4540] thread_get_buffer() failed

[h264 @ 0x7f178c0e4540] decode_slice_header error

[h264 @ 0x7f178c0e4540] no frame!

And the same message repeats forever.

Here's the source code files I'm using:

Form1.cs

Program.cs

It's based on the sample provided in the LibVLCSharp git project. All the references and packages are provided.

Any help will be greatly appreciated!

With regards, Pawel
