[mythtv-users] mythtv can not work with HW MPEG2 encoder of AUSU PVR-416

[Clark Lee]

Dear Nick,

I have checked again and seems the ownership/permission are ok, as follow:

clark at clark-desktop:~$ ls -l /dev/video? -l
crw-rw----+ 1 root video 81, 0 2009-06-27 21:08 /dev/video0
crw-rw----+ 1 root video 81, 1 2009-06-27 21:08 /dev/video1

mythbackend, which is under debug, is run with user clark,
and clark is a member of 'video' group, as shown in /etc/groups;

The error message:
2009-06-27 22:23:34.206 MPEGRec(/dev/video1) Error: error reading from: /dev/video1
            eno: Input/output error (5)
2009-06-27 22:23:34.206 MPEGRec(/dev/video1) Error: error reading from: /dev/video1
            eno: Input/output error (5)

However, if user clark run cat /dev/video1 > foo.mpg, it will correctly generate a mpeg 2 file.
I am really puzzled here...

Clark

What is the ownership/permissions of /dev/video1?

What user is running mythbackend and is that user in the correct group
to access /dev/video1 (bearing in mind the answer to the first
question.)?
