My mac mini frontend seems to be working fine. I use the HDHR to record on
a remote backend. Everything works fine.

So open a trac ticket at code.mythtv.org and provide a link to a sample.. A

I'm still having the issue, I've provided a sample for testing. I'm
unsure what I else I can do to help fix this issue.

Re: 0.25 on mac-mini [In reply to]

This is related to the HD-PVR not the HDHR....

Does anyone know if there is a ticket number for this issue?

Re: 0.25 on mac-mini [In reply to]

So I've noticed that some 720p recording work and others don't. Any Law
& Order (regardless of channel) or Public Broadcasting show in 720 don't
work, while ESPN MSL soccer games in 720 always seem to work.

Is there a ticket # for this issue yet?

Try this:
http://www.avenard.org/files/mythtv/mac/MythFrontend-v0.25-105-g6970413.dmg

(will take about 10 more minutes from the time of this post for the
upload to be complete)

Then run mythfrontend with:
Start a Terminal
Go in the folder where MythFrontend.app is located

And start it that way:
./MythFrontend.app/Contents/MacOS/MythFrontend -v audio,playback -O
AllowVDAInterlace=1

Then go into Setup -> Video -> Playback
Select "VDA Normal" in the profile list.

Try playing your HDPVR video again

My guess is that earlier on, you were using the VDA hardware decoder.
In 0.25, interlaced playback is disabled via the VDA decoder (just
like it is disabled in VLC and XBMC) as it can cause kernel panic
(like BBC HD will seriously crash your mac)...

There's no way your mac would have played a HDPVR stream without
hardware acceleration. Quartz available on a 0.24 build wouldn't have
helped, because Quartz only works on MPEG2 video. Your HD-PVR outputs
H264 only.
So all that search in building a 32 bits build I read earlier is useless.

And for H264 hardware assisted playback: there's only VDA available on a mac.

Re: 0.25 on mac-mini [In reply to]

Hi

With more details provided on this ticket:
http://code.mythtv.org/trac/ticket/10749

Here is a 32 bits build built against Qt 4.6.4
http://www.avenard.org/files/mythtv/mac/MythFrontend-i386-v0.25-146-gb1b516e.dmg

This build has no playback issue on a mac mini 2010 with the HDPVR
sample provided.

Hi Jean-Yves,

Would you recommend this build for all older (Core 2 Duo) macs?

If so, should we create a new profile with no processing, as is
described in the ticket, or should we just use VDA Normal?

Thanks-

From what I tested, 32 bits code on a core 2 duo runs faster than 64 bits..
So yes, on those machines I would recommend using this 32 bits build. Or
you could use a universal build and force 32 bits mode.
I found that using the carbon version (with Quartz video) doesn't help at
all.
Interestingly, on a new i5, i7 versions, 64 bits runs quite a bit faster
than the equivalent 32 bits code, almost 14% more fps on the same media

you get a kernel panic... So if your primary intent is to play interlaced
video, no point in select a VDA profile.

Thanks. This build (using Normal profile) does use less CPU than the
64 bit build from source forge.

However, for this build, playback seems always to default to a forced
4:3 aspect ratio. The only way I could figure around it was to force
16:9 aspect ratio in the playback settings. Had you noticed this?

It's using Qt 4.6 as I also wanted to include carbon framework... So there
are likely going to be some weird issues occurring as 4.6 and 4.7 on a mac
has quite a fair amount of problems.

But no, I didn't notice that one..

Well, the 4:3 seems to be the only issue with this build that I can
find. Otherwise, the playback performance is very good.

Thanks again-

Re: 0.25 on mac-mini [In reply to]

I've just received notifications from Apple that the VDA bug I
reported that prevented interlaced media to be properly decoded has
been fixed in Mountain Lion Preview 4

Mountain Lion is supposed to come out next month.

I haven't tested if they indeed fixed the issue or not

What you describe in the ticket sounds exactly like what I'm seeing, and
very likely what the OP is getting.

Well, that was hardly a fix...
Instead of crashing they now return an error when trying to decode the
file , but they certainly don't play the file, so the BBC HD sample
like this one http://dvb-antares.com/ftp/HD/BBC_H264_test6.ts

requires an incredibly high cpu usage

I realie you are testing VDA, but how much CPU usage is normal? On my
late 2008 Core 2 Duo MacBook Pro running 0.24 (Standard decoder,
quartz-blit renderer), the clip plays smoothly at 90-120% CPU usage
according to Activity Monitor.

That one yes...

Oh..

And you are using a 32 bits built.
On Core 2 Duo, 64 bits code runs slower than 32 bits one believe it or not...
The situation is reversed on newer intel..

This actually makes some amount of sense. The Core 2 Duo was
shown to be slower in 64-bit mode (than 32-bit mode) for some
class of workloads (and faster in others). Apparently, MythTV is
part of the former set. I also have this vague recollection that
on some particular Apple systems, if your system does not
have the appropriate 64-bit EFI bootrom, you ended up running
a 32-bit kernel, which means every 64-bit call may be going to
go through some sort of ugly "thunking" layer. But, never
having owned any of the fruit-themed vendor's products, this
last part is really all conjecture.

Hi Nigel,

It took a little while to sort this out, but for me the problem
appeared between v0.25-62-g3d29f7c and v0.25-146-gb1b516e.

Interestingly, however, it does occur on my Mini running 10.7; it only
occurs under 10.6.

HTH,

Steve
