[Bug 665505] [NEW] TV board HVR1300 : MPEG2 decoder not initialising correctling at boot time

[boblinux]

Public bug reported:

Hello,

I bought one or two years ago this board, with an MPEG2 encoder. The
cx88 driver creates three devices :

/dev/video0 : I don't remember if it's useful, I discarded it when I
learned how to use these devices

/dev/video1 : this is the normal, not-MPEG processed TV device

/dev/video2 : this one gives access to the MPEG decoder

in order to enjoy a high TV quality, I enjoy looking the TV using
/dev/video2;  for that I use generally :

mplayer -vc mpeg12 -nocache /dev/video2

but

mplayer /dev/video2

or

vlc /dev/video2

work correctly as well.

However, there is one problem : after each boot, connecting to
/dev/video2 with whatever command opens a blank window; I have to first
connect to /dev/video1, I use for that :

xawtv -c /dev/video1

here I get a normal TV window; then I close it. Now, and now only, can I
connect on /dev/video2 and get the MPEG-decoded TV image.

I have been having this bug across many kernel updates, I have waited at
least one year. Other bugs have been repaired invovling this driver
(such as boot stops) but not this one, so I eventually post this bug
report.

It looks like a bug in the cx88 driver ?

Whay can we do ?

Best regards
R. Grasso
