YUV420 crash in recent version of OBS.

[MarioMey]

I know that a new maintainer is being looked... but I will post this, anyway.

I was using v4l2sink in YUV420 with OSB, compiled here, commit 355cd6ccc0f8435fc1d45043e2ffa1f74ee36b94 (Date: Thu Apr 16 19:41:11 2020 -0500). It works well in that version with that format. Today I pulled the last commit: 002886bbac4c176ff16d64ab6ec9c1fe6a3e9154 (Date: Sat Jun 27 05:16:59 2020 -0700), and v4l2sink makes a segment fault when it starts.

I just realized that YUY2 does work... I never used it, because I don't understand well these formats and I prefered to choose the default one.

If you can tell me how to debug it, I could do it... if helps for something.
