Survey on Video Capture API: BSD meteor(4) vs. Video for Linux 1/2

[Intron is my alias on the Internet]

If I would code to enhance video capture support for FreeBSD, what video
capture API do you prefer? Your choices:

1. BSD Brooktree 848 (See bktr(4) and meteor(4))

This is *BSD-specific video capture API. So far only Brooktree
(Conexant) 848/878 chip is supported by *BSD. Thus, actually this API
is BT848/878-specific.

2. Video for Linux 1/2 (See http://v4l2spec.bytesex.org/)
      
These are the video capture APIs for Linux. There are two versions:
V4L and V4L2. Supported hardware list:
     http://linux.bytesex.org/v4l2/drivers.html    (V4L2 mainly)
     http://mxhaard.free.fr/spca5xx.html           (V4L)

MPlayer supports both kinds of API's. But to gain Linux binary
compatibility for FreeBSD, V4L/V4L2 must be introduced to FreeBSD.
