Hi,

I've tried running mplayer v4l2 input on a bt878 card, and it fails.
xawtv works fine, and 2.6.14-rc5 used to work fine.

On git 3b44f137b9a846c5452d9e6e1271b79b1dbcc942 :

$ mplayer  tv://1 -tv driver=v4l2

BTTV currently only supports v4l1. We are still in the process of porting the bttv driver from v4l1 to v4l2. Nickolay is working on it.

Hi,
I've noticed that mencoder no longer works with bttv capture on my system; with today's git tree (ec1890c5df451799dec969a3581ff72e1934b5ee), 
while it used to work on 2.6.14-rc5.
xawtv functions.
I'm looking for people who experienced the same problem,
or possibly for a fix.


The devices are:
0000:03:0b.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)

0000:03:0b.1 0480: 109e:0878 (rev 11)


I'm using mencoder Debian package '1:1.0-pre7cvs20051102-0.0' from marillat's
for x86_64 architecture.
