I'll give this a go and report.

Packaging the frontend in a bundle is great; I've said so repeatedly.
MacPorts and the bundled apps are geared to quite different use
cases. For those of us that want to run the full system on OS
X--including the backend--bundling makes it harder. My work on
MacPorts is all about making it easier to set up an OS X backend.
Plists so it automatically runs on boot up, logging (and log
rotation) in a rational location, full suite of myth* programs,
functional Perl and Python bindings for backup and metadata, etc.
Honestly, why do you, a developer, want to be in the packaging
business anyway? There are upteen MythTV packagers out there. Why
is one more, MacPorts, an issue? Homebrew has a half-assed version.
Long ago, Fink had one. Myth is just another software package.
Building a functional version should not require special magic. I
see questions from other packagers from time to time on the Myth
mailing lists. They have problems, I have problems, hopefully the
problems get sorted out.
BTW, a side issue: why do you include MythBrowser, MythNetVision and
MythNews in the frontend bundle? None of those are actually

The fact is, I've reported 15 tickets in 3+ years , four including
patches. One is closed "Invalid"--yes, bizarre hardware problems led
me to believe there was a code fault. I admitted I was wrong and
asked that the ticket be closed . Not "a majority", not "almost
all circumstances", not "several cases".

Let's review the AirPlay ticket . I started testing in August
2013 and we went back and forth through September (when I filed the
ticket) without determining why Video AirPlay worked for you and not
me. You found and fixed a problem in October . I updated but
that didn't get me any further. In January, another user reported
what seemed to be the same problem I had . From time to time, I
retested but had nothing new to add to the ticket.
Four days ago, you committed some changes , noting "Since the
release of iOS 7, AirPlay? has been very much unusable." IOW, the
issue I reported 6 months ago was, in fact, valid.
Now, I'm trying to confirm that the issue is actually resolved.
Perhaps the remaining problem is due to the MacPorts implementation
of Qt4. As my last email showed, the current AirPlay implementation
isn't exactly 100% reliable with the bundled app. If MacPorts is the
problem, I'll follow up with the maintainer of the Qt4 port to get it

The commit referenced above , says "Thanks to Memphiz from the
XBMC team to figuring the cause." I took that to mean that they had
a working implementation. I apologize for misunderstanding.
Keep in mind that I want AirPlay to work!! It is a seriously cool
feature and I think being able to display iPhone photos and videos on
a frontend machine is an awesome feature that will get people excited
about Myth. Particularly folks that have invested in the Apple
ecosystem--folks that are likely to want to run the backend on OS X.
Would you rather get no feedback? If I test and find it doesn't
work, should I just shrug my shoulders and move on? You sure aren't
getting much from other users.

Two can play that game--it is not 100% on something *you* compiled
and packaged. Rather than guess, let me build another test version
incorporating the patch and see what it tells us.
