Re: Various problems with MPEX EMPRESS board (saa7134 driver)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I have also been looking at the Transport Stream support in the driver. Interestingly, I get data out of the stream, even though there is no data in the stream (I have no source of data). This suggests to me that something is not working quite right. I'm using an FV2K board with a modified driver that makes it think that it has a transport stream source on it.

Hi Gerd,

I've been evaluating one of the MPEX EMPRESS boards with snapshot
20030813 and
Kernel 2.6.0-test3. So far no joy.

First, the driver doesn't select the correct video source (at the
hardware level)
when a source is chosen by the user. A small patch is attached.

Second, I can't seem to get an MPEG stream out no matter how hard I try.
If you
have any hints they'd be greatly appreciated. I've experienced various
strange
Behaviour: process locking - Once a process accesses /dev/video1 it
becomes wedged
and can't be killed; total system lockup; no TS data from /dev/video1
(all 0x00...).

On a side note I've been inspecting the internals of the driver and am
partially
Confused by the way i2c commands are issued. It appears that the routine
'i2c_clients_command' issues the request command to all devices on the
i2c bus.
For example, an i2c command to drive the tuner will also result in an
unknown
command being passed to the 6752? Is this normal? (or correct -
diagnosis maybe wrong).

I've used the card with the Windows drivers and it truly generates some
excellent
transport streams. Can't wait to begin using linux.

Thanks,

  -Greg
