em8300 and ALSA problems

Hi,

I really want pulseaudio badly and since it doesn't work very good with OSS output, I decided to switch to
ALSA. However, I'm running into some problems with ALSA. My dxr3 (em8300) card seems to be detected by ALSA
(/proc/asound/cards lists it too): 

[root <at> server ~]# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: I82801BAICH2 [Intel 82801BA-ICH2], device 0: Intel ICH [Intel 82801BA-ICH2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: EM8300 [Sigma Designs' EM8300], device 0: EM8300/0 [EM8300 DAC]

card 1: EM8300 [Sigma Designs' EM8300], device 1: EM8300/1 [EM8300 IEC958]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

But for some reason it won't play anything:

[root <at> server ~]# alsaplayer --verbose -o alsa -d hw:1,0 Strong.mp3

The device is supposed to be big-endian only.  Try plughw:1,0
instead to convert endianness.

Yes, that seems to work! Only for analog output though. When I try with digital I get the same error again.

DXR3 and Atmolight Plugin

Hi,

I´m using my VDR with a DXR3.
Now i want to use the Atmolight plugin.
Which needs the possibility to grab the image of the output device to 
analyse the colours.
Is there a possibility to grab the images and send them to the atmolight 
plugin?
I heard in the vdr-portal.de that there was a possibility in an older 
version.

Greets,
Sebastian

The last time it was available was in < 0.2.5 versions of the VDR DXR3 plugin.  
But it probably was broken already for quite some time back then.  From the 
plugin's HISTORY file:

2006-01-08: Version 0.2.5
- remove image grab code, it's broken (crashes vdr) and would cause
  maintenance problems with various 1.3.x vdr versions (Ville Skyttä)

Hm, that coming from me sounds pretty odd, because I don't remember ever 
actually using ALSA with a DXR3 (apart from maybe some very quick tests), and 
I'm clueless wrt. ALSA configuration in the first place.

Oh right, it was Nicolas. I just read through the Changelog and stopped on
the first entry :)

Maybe he can shed some light into this.

interlaced tv-out

Hi,

I have a box with 2 dxr3 cards which I use to stream movies via dxr3 
tv-out to RF modulators which are then received and displayed on 
multiple TVs.

Everything works fine, except with interlaced PAL movies.
The interlaced parts of the movies appear on the TVs jumpy, like the 
interlaced parts are displayed in reverse order.

The movies are encoded to MPEG2 with mencoder and are played with 
mplayer -vo dxr3.
Of course the movies are played without any issues in Linux and Windows 
client on normal computer monitors.

Initially I thought this has something to do with the dxr3 firmware, so 
I tried the ones supplied by RealMagic (all 3 of them). However the 
issue remains when the movies are displayed on TVs.

Is this is a fault of the dxr3 module of mplayer? (mplayer plays them 
normaly on computer monitors).
Any other ideas?

Kind regards,

Costa
