Hi,

Still waiting on some time to rebuild it and get sound working, but checking the forums.

bye

Hi,

I too have a EPIA 10000 and a PVR350 card.

mythtv does not seem to use the mpeg decoder since the cpu use is about 98%
during play when I run over TV-out on the 350. This is with the sound and picture
being very lagging.

Have you(or anyone) succeeded in getting the mpeg decoder to work ?

You don't seem to be using the PVR 350's accelerated video, but you do seem to be using the PVR 350's TV out based on what you said. This means you've compiled ivtv and set up your XFree86 for the 350.

All you need to do in this case is make sure that in your MythTV set up (somewhere in Set Up and TV Settings) that you have the "Use PVR 350's accelerated video" checked. I don't think those are the exact words, but it's similar to that. Now all your video and audio should be pumped out of the PVR 350 and your CPU utilization should be close to zero.

I found that now, thank you.

Now it seems that the tv picture jumps up and down a few scan lines about once a second.
very little but definately noticeable. I live in denmark and uses PAL.

Hi Pete,
How are the instructions going?

I was wondering if it is possible for you to release the instructions in there current state?

Pete,

I second that idea. I'd LOVE to at least give this a try. Seems like a good way to get a lot of feedback, too.

BTW, thanks for putting the instructions together - even though we can't try 'em out yet

did the manual, walkthrough ever get posted anywhere?
i'd like to build these ... mythtv clients

Kernel update

Answer the questions with no, then yes.

After the reboot close the 'enter root password' window
left click on the desktop select XTerm and continue


ivtv


lirc

edit drivers/lirc_i2c/lirc_i2c.c
comment out
request_module("bttv");
request_module("rivatv");
by adding // to the start of the lines
As with the 250 we don't need these


alsa 1.0.5



fix ivtv
because of the via_v4l driver ivtv will now be video3 onwards


setup the via modules

Quit the frontend
left click on the desktop and select XTerm and continue

-----------------------------------------------------------------------------------------------------------------

via epia M X11 drivers


edit /etc/X11/XF86Config-4

set the module section to look like this

Section "Module"
Load "ddc" # ddc probing of monitor
Load "GLcore"
Load "dbe"
Load "v4l"
Load "drm"
Load "dri"
Load "extmod"
Load "glx"
Load "bitmap" # bitmap-fonts
Load "speedo"
Load "type1"
Load "freetype"
Load "record"
EndSection

Change the "Device" section with card0 to look like this

Section "Device"
Identifier "card0"
Driver "via"
Option "DPMS"
Option "TVType" "NTSC"
Option "TVVScan" "over"
Option "TVOutput" "S-Video"
Option "ActiveDevice" "CRT,TV"
EndSection

open GL interface libs


MPEG lib


mythtv rebuild

edit settings.pro
change
QMAKE_CXXFLAGS_RELEASE
to
-march=i686 -msse -mmmx -mfpmath=sse -O3 -pipe -fomit-frame-pointer
change both ocurrences of /usr/local to /usr
uncomment cle266 and lirc

get lots of tea

#set mythfrontend to run as root to allow access to the cle266 decoder
cd /usr/bin

chown root mythfrontend
chmod a+u mythfrontend

cd ~
mkdir .mythtv


Congratulations!

The wiki has a page for this.

If you find problems putting the solutions there would help others.

Also if anyone knows wiki markup and can copy the instructions into the wiki so others can edit them that would be great.

http://knoppmythwiki.homelinux.org/inde ... therboards

It's been added to the wiki, I think it's ledgable, but not beautiful. Hopefully someone with too much time on their hands will come along and pretty it up.

If anyone finds problems with this or has improvements please add them to the wiki too.

Thanks

Hi,

Without dma the picture is very jumpy, I've seen some posts in other groups compaining it's not stable with it. I've been runnning it with for a few hours and not had a problem. So here's how

As root, as always


To check harddrive speed try

I get over 20MB per sec which is plenty for upto the highest bit rate of 12Mbit/sec. Without dma I only get 4MB which isn't quite good enough.

I got to the kernel update part and did exactly as it said (I was a bit confused that only make dep is
called, and not "make bzImage modules modules_install install") and it all worked until I came to:

:
:
root@r2d2:/lib/modules # mv /etc/modutils/1alsa ~
root@r2d2:/lib/modules # mv /etc/modutils/actions ~
root@r2d2:/lib/modules # update_modules
-su: update_modules: command not found

What am I missing?

On another note, I noticed the compiler flags:
HOSTCFLAGS = -Wall -Wstrict-prototypes -O3 -fomit-frame-pointer

Isn't the epia better suited (due to less cache) with:
"-Wall -Wstrict-prototypes -march=i686 -msse -mmmx -mfpmath=sse -Os -pipe -fomit-frame-pointer"

?

well the reason that you didn't actually make bzImage is because you are merely configuring the source so you have something to build the modules against. you are not creating a whole new kernel.

as for the command not found it is update-modules not update_modules

note that tab completion would have found this for you quickly, if you do not know what that is you can type in part of a command and hit the tab key and it will finish it for you unless there are more than one commands that start with what you have typed, and in that case hit tab key twice and it will give you a list. This function is a godsent for people like me who have problems remembering lots of commands particularly when everything is case sensitive.

Will this work seeing that the Knoppmyth kernel has a different minor-version:

root@r2d2:/lib/modules # uname -a
Linux r2d2 2.4.25-chw #1 Sat Apr 10 15:46:31 PDT 2004 i686 GNU/Linux



Ah! *bonk* Of course. If had bothered to read further down. I just cut'n'pasted from the text,noticed the error and jumped the gun. Thanks for the help.

In the cook-book it says:



However, since the Epia C3 has a rather small cache, wouldn't -O3 flood the cache? Has anyone tried -Os?
