Re: [Vala] V4l2 - STREAMON Fails

Hi,

It's not clear what your problem is, can you explain exactly what you
did, what you expected, and what error you got?

Anyway, see below for a guess at a solution.

That's probably a bug in the vapi, try adding cname to the CCode
annotation like :
[CCode (cprefix="V4L2_BUF_TYPE_", cname="enum v4l2_buf_type")]

I'm confused, is this supposed to be a question or an affirmation?
Anyway, if it should be &type, then you should write it as &type in the
vala file.

HTH,
