[Mvpmc-users] New Dongle

[Bernhard G. <ge...@ge...>]

Source is on github: https://github.com/citronalco/mvpmc/
Binary dongle download: https://github.com/citronalco/mvpmc/wiki

No functional changes, so LiveTV and TV Guide still don't work, I only
merged most of the updates of Gettler's cmyth library.

[Mvpmc-users] Updated Dongle

[Bernhard G. <ge...@ge...>]

I don't know if anybody out there still uses the MediaMVP. I do.

This time I was able to use the most current release of Jon Gettler's
libcmyth, which means the dongle is supposed to work with MythTV >= 0.27.
LiveTV still does not work.

New Dongle:

No, I have no such plans to do that.

If you look at tvguide.c, it clearly never should have been placed in
libcmyth, which is why it got removed when libcmyth was pulled out into its
own repository.  It is too tightly coupled to the mvpmc application, and
really should have gone in the src directory.

So what sort of things did I break?  I didn't really intend to break any
users of libcmyth, but I also didn't test my changes with mvpmc.

Thanks.

Yes, mvpmc's user base is most likely very small for sure.

Currently I'm having some trouble with mvpmc's tvguide functionality. It
relies on tvguide.c which was afaik only part of mvpmc's cmyth but never
included into the standalone libcmyth. Your latest livetv changes broke it
completely, which is really too bad as I had mvpmc working with cmyth
before. As you are adding more and more functions to cmyth: Do you have any

Right, which I was surprised to learn, back when I first ran into memory
issues.

Correct.

Does libcmyth pass a pointer to the entire show list, or does it have a
function that gets called iteratively to return the next show in the list?

If the former, then post-processing the structure to prune it might help
in some cases, but you could still hit the memory ceiling before you
even get to the post-processing. Not to mention it would be inefficient.

But post-processing pruning is what's happening now and it doesn't seem
to work. Is that because the data structure is still kept in full, but
filtered as it is rendered to the GUI? Or is the memory from the freed
records not being reclaimed by the heap? (With only one application
running, that the memory doesn't get reclaimed by the OS shouldn't matter.)

Ideally, libcmyth would be able to use the passed filter to make a more
narrow request from the back-end, and save the effort of even sending
the unwanted shows over the wire.

> memory?

I've posted numbers of episode counts at which the problem started
happening, which should be in the list archives. My recollection was
that it was around 1000 episodes, give or take a few hundred.

If you have archives and multi-terabyte disks, exceeding that is pretty
easy.

After looking at the code, it would be relatively trivial to ensure that
the first program list is freed prior to loading the second one (change
load_episodes() to free the old list first).  The problem would be that you
would introduce a race condition such that if the reload occurred at the
same time as the new list was being loaded, the GUI would probably present
an empty list.

It is better than locking up, but still not ideal.

Currently, you can use the config file to save your settings for which
program groups to hide.  However, the program list is pruned after it is
entirely loaded, so I guess that isn't a solution for you.  To solve your
problem, you'd probably need to pass some sort of filter to libcmyth so
only a partial list is returned.

BTW, any idea how many recordings you need to run the MediaMVP out of
memory?

Meaning you might be navigating through the show list and suddenly the
list entirely disappears, pauses while the reload happens, and then you
have to start navigating again from the top of the hierarchy?

Agreed, that would be disruptive, but once you've exceeded the memory
threshold, the reality is equally disruptive: you're navigating through
the show list and suddenly mvpmc puts up a partially rendered "please
wait" dialog and hangs, your only recourse is to power cycle, and then
you have to start navigating again from the top of the hierarchy.


> A more "clever" way...the code could recognize that a proginfo

Agreed. Though more code to accomplish that, and performing the
duplicate checks will probably slow down loading the show list.

In any case, handling the refresh problem doesn't go far enough once
you've exceeded a second capacity threshold. If I don't "hide" a portion
of my show database from mvpmc, even a single copy of the show database
loaded into memory causes the UI to slow down to be barely usable, and
it impacts playback such that it is very difficult to achieve audio sync.

So if I was prioritizing between these two hypothetical enhancement, I'd
consider filtering on recording group to be far more useful.

Any idea what is broken?  If not, it is certainly a lot easier to test with
some of the test programs in cmyth (https://github.com/cmyth/cmyth).

The ideal solution here would be to transition mvpmc to use the libcmyth
repository on github, instead of the built-in version.  Then any fixes in
the library would be available to mvpmc without having to be back ported
into an older code base.  However, I really have no idea how much interest
there would be in doing that, or how much use mvpmc is even getting these
days.  Personally, I haven't used it in years.

I suspect that is easier said than done, although it would make perfect
sense.  Since all the data structures are reference counted, any reference
to any program will keep it in memory.  The only way to purge the list
first would be to clear the GUI, which could be disruptive to the user.

A more "clever" way to deal with this would be to deal with it inside
libcmyth, so it is transparent to the application.  The code could
recognize that a proginfo structure is a duplicate, and increment the
reference on the original and toss the duplicate.

How about an antique 0.21.0+fixes?

I've frozen my MythTV install until I get around to building new
back-end hardware. (And it has been several years since I tried a new
dongle. After encountering bugs I stuck with an older version.)

I was hoping to transition from mvpmc to XBMC using the MythTV PVR
plugin, but after getting it all set up, I discovered that the XBMC
developers gutted support for old MythTV versions from their fork of the
cmyth library.

Nice.

I'd also disable the automatic refreshes that occur when the back-end
tells mvpmc that new recordings have started. When you are marginal on
memory, all it takes is one refresh and you need a power cycle to
recover. I'd rather just not have any refreshes occur until I manually
power cycle.

It's been discussed here before, but there are a couple of straight
forward architectural changes that could be made to greatly reduce the
memory footprint of the show data.

One would be to free the current list from memory before loading a new
list, instead of trying to keep both the old and new list in memory at
the same time. (Though irrelevant if the changes above were made.)

The other would be to filter the shows per the recording group selections.

I've found an ugly SQL hack to emulate the latter. The query that
clients use to load shows includes a clause to skip shows that have a
deletepending flag set, so a bit of SQL can be used to set that flag,
which the back-end ignores (it doesn't delete the shows). However,
there's a hitch. The query also looks at the timestamp on the show
record, and ignores the deletepending flag if the timestamp is older
than 5 minutes.

So I ended up with this shell script:

file: hide_archives
-----
#!/bin/sh

# you need to change something on each update, or it won't update the
# timestamp the calling code should cycle through values
DEL=${1:?}

if [ -e ~mythtv/.hide_archives-off ]; then
  exit 0;
fi

/usr/local/bin/mythsql \
 -e "update recorded set deletepending=$DEL where recgroup='archive' or
recgroup='Long Term'"
-----

and then this is called periodically from cron:

# Add hack to suppress archived recordings from show listing query.
# Runs every 4 minutes, which is < 5 minute criteria.
3,15,27,39,51 * * * *  /home/mythtv/bin/hide_archives 2
7,19,31,43,55 * * * *  /home/mythtv/bin/hide_archives 3
11,23,35,47,59 * * * * /home/mythtv/bin/hide_archives 4

A couple of other trivial scripts (hide_archives_off, hide_archives_on)
manipulate the .hide_archives-off file, which when present, disable the
hiding so you can access shows in the hidden groups.

file:hide_archives_off
-----
#!/bin/sh

touch ~mythtv/.hide_archives-off

/usr/local/bin/mythsql \
 -e "update recorded set deletepending=0 where recgroup='archive' or
recgroup='Long Term'"
-----

I've been running this for about 6 months or more with no adverse effects.
