Subject: [PATCH] Suggest workaround for error 0xfffffc0e

When the hardware encoder is not able to encode at the given definition,
it fails with an error 0xfffffc0e.

It is documented in the FAQ:
<https://github.com/Genymobile/scrcpy/blob/master/FAQ.md#i-get-an-error-could-not-open-video-stream>

But it is better to directly suggest the workaround in the console.
