MythTV on PPC

Has anybody tried MythTV on apple hardware. I would like to run
at least the frontend on PPC hardware.

Any reason why this won't work?

Since this seems to be happening with some regularity -- if you're going to
cross-post between the -dev and -users list, you better have a really good
reason to do so. I don't consider asking a question that's already been
discussed on the lists a 'really good reason'.

I have the frontend working on Linux/PPC. It required some
big-endian patches. I can post these patches if there's interest. I
was trying to get it working on MacOSX but it turns out that there is
no Xv support and X11 ShM is not usable. I need to try it again after
the recent non-ShM mode fixes. Adding SDL support to Myth may be the
way to go but it's not something I can try to do for now.

Yes, I would love more info and patches to get mythtv compiled on ppc.
I gave it a whirl today, but I don't think I had much of a chance,
since I don't know much about this stuff. I don't even know what the
hell "big-endian" means. Anyway, here is what I did.

Today I tried to compile mythtv today on an slot loading imac G3 400
mhz with mandrake 9.1 ppc.

It failed even when I changed settings.pro from:

release {
DEFINES += MMX
QMAKE_CXXFLAGS_RELEASE = -O6 -march=pentiumpro
-fomit-frame-pointer -funroll-loops -fexpensive-optimizations
}

to

release {
DEFINES += MMX
QMAKE_CXXFLAGS_RELEASE = -O6 -march=powerpc
-fomit-frame-pointer -funroll-loops -fexpensive-optimizations
}

got a similar error when I tried 'ppc' rather than 'powerpc'

I guess that isn't the only change I have to make. Any help would be
appreciated. Thanks

Cedar

this is the error I got:

Super, I'm looking forward to it.
Maybe at the same time you can enlighten me about this big-endian
issue. I've done a bit of poking around and found a couple of things
that suggest that PPC supports big _or_ little endian words. Here are a
couple of quotes I found on message boards:

> run in either mode, Apple uses the PowerPC in big endian mode. The
> IA32, by contrast, is little endian, and can only run in little-endian

I also found this:

> possible and desirable to limit the endian-sensitivity of software to

I'm just curious why with whole distros and all their packages compiled
for PPC, why mythtv has a problem with this issue? Or did mandrake
have to patch/port all those packages, fixing the endian issue one
package at a time? Also, I've compiled a number of programs from source
on linux ppc and more often OS X and not run into this issue. What is
different about myth? Is it something inherent to writing a pvr
program, or is it just a failure to write portable code?

Finally, when I compile for ppc what else do I have to do other than
apply your endian patch? The compile error I posted earlier seemed to
suggest that I had not set the arch correctly? The heart of the error
seemed to be:
cc1plus: invalid option `arch=powerpc'
What does a correct settings.pro file look like when compiling for ppc?

thanks again for your help!

Re: MythTV on PPC [In reply to]

Here are patches against CVS a few hours ago to make
mythfrontend work on PowerPC machines running Linux (tested on Debian
stable). I have also patched backend routines but have no way to test
them so they may be incomplete (x86 still works).

My 400MHz G4 can just about decode 480x480 mpeg4. Altivec
routines in libavcodec are unused (don't have a compiler that supports
them). Live previews are a bit garbled -- I think the patches to
yuv420_argb32_non_mmx are correct but my machine just can't keep up.

Developers, let me know if the changes should be done
differently. The edits to the .pro files to include config.mak are
ugly but it seems that nested includes with relative path names don't
work properly so including it from settings.pro didn't work. These
changes could be dropped if the user just edits settings.pro instead
of using the result "configure". Or maybe there's a cleaner way to do
this.

I've just sent my patch to the list. Give it a try. I'm not
sure Isaac will accept it soon so I'd appreciate it if someone else
could test it. You can apply it with "patch -p0". For your G3, I
think you can edit "settings.pro" and change "-mcpu=7400" to
"-mcpu=750". Let me know if you run into problems.

MythTV is affected because the nuv file is a binary file which
has little-endian fields in some headers -- these fields need to be
byte-swapped so that they're interpreted correctly on PPC. The pixmap
RGB and sound stream formats are similarly affected.

MythTV is not really different from any other software that
reads/writes binary files. It's just that most Unix software works
because they've already been ported to big-endian machines (like Sun,
HP, and IBM workstations). For older stuff, they may have even been
developed on big-endian machines. I guess it's really only when new
binary file formats show up that some porting needs to be done. (I
remember when xmms would just generate screeching sounds on LinuxPPC!)

Re: MythTV on PPC [In reply to]

This is a terrific step! Congratulations..

Could this possibly lead to a port to TiVo's hardware? (ppc based, if
I'm not mistaken)?

Wouldn't it be easier to byteswap the frameheaders on load/save? I know you
asked before, but..

I thought it might be better to keep the structure details in
format.h, but I agree it's less intrusive and probably safer to do
what you say. I'll change it and try again in a few days.

Re: MythTV on PPC [In reply to]

well, I had time to try out your patch. It applied cleanly and using
"750" for the arch seemed to do the right thing. Once installed I gave
it a whirl with mixed results. The frontend worked beautifully.
Watching a recording also yielded really great looking smooth playback
of my 480x480 mpeg4 recordings. I was pretty happy that my old 400mhz
imac could do that (and easily it seems!) However, recordings had
messed up sound. It sounded like HAL from 2001 when he is being shut
down. Slowwww and lowwww. Sounded like a drug trip. However, the sound
did seem to somewhat match the action.

Console showed this message:

[cedar[at]localhost cedar]$ mythfrontend
connecting to backend server: 192.168.1.102:6543
Setting PCM volume: : Invalid argument
Reading PCM volume: : Invalid argument
Changing from None to WatchingPreRecorded
audio device cannot report buffer state accurately,
audio/video sync will be bad, continuing anyway
Over/underscanning. V: 0.000000, H: 0.000000, XOff: 0, YOff: 0
Using XV port 61

Otherwise sound seems to work fine on this system with Mandrake 9.1. I
know that doesn't really make it myth's (or your patch's) fault yet,
because a lot of people seem to have working sound, but still have
trouble getting sound to work with mythtv. However, I'm not trying for
recording and playing at the same time so I don't need duplex, so I was
hoping it would just work. Any ideas?

I thought of manually installing alsa from source since that worked to
get my x86 mandrake 9.1 sound working with mythtv, where the included
alsa didn't work for me. But I don't know the name of the sound card in
this imac, and couldn't really figure it out from the sound cards page
on the alsa website, so i didn't do that.

Finally, here is my modules.conf file:

alias eth0 gmac
probeall usb-interface usb-ohci
alias ieee1394-controller ohci1394
alias sound-slot-0 dmasound_pmac

pretty simple eh? Anyway, if anyone has any advice, or success getting
this going on an imac, I would love to hear about it. In the meantime I
appreciate your work with the patches, I'm a lot closer than I was
before!

best,
Cedar

ps
Mandrake 9.1 seems really snappy on my imac! It rivals the
responsiveness and perceived quickness of my much faster amd system.
However that impression was different during the compile. That took a
really long time.

Yes, you'll need CVS from around that time to use that patch
(which might be difficult due to the repository change). I
occasionally update my local tree and can try to generate patches for
more recent CVS builds if you're interested.

Thank you for you help! I think I'm headed in the right direction now. After
doing:

$ cvs -z3 -d :pserver:mythtv[at]cvs.mythtv.org:/var/lib/mythcvs checkout

This there something I am missing here?

Thanks again for your assistance. I want to make sure I exhaust my options
with this current patch before requesting that you try to make another.

Done. That part was easier that I thought!

After making that change in mythtv/main.cpp, it compiled on and gave me the
same error for mythepg/main.cpp, so I made the same change to that file.
That brings me to the latest error:

At this point, would it be easier to have you generate a patch for a version
of MythTV after the CVS change? I would be very interested in that if you
think continuing with this current patch is too much of a hassle.

Thank you very much for your help and time. It is much appreciated!!! I'm
very excited about getting MythTV to work on my Powerbook via 802.11b. Once
I get it compiled, I'll let you know if the video preview works correctly.

Thanks again,

Patrick

Re: MythTV on PPC [In reply to]

Gregorio,

Your patched applied cleanly and mythtv compiled just fine, but I'm
having trouble connecting to my master-backend. So as soon as I get
that fixed, I'll let you know if the video preview works.

Thank you for providing that patch!

Patrick
