How to record everything all the time ?

Hi,

I have got got 12 dvb devices and would like to record every movie
everyday on every channel forever (unless previously recorded).

If the rule can be setup using mythweb that would be great.

Does anyone know how I can do this ?

I would also (secondary) like to record everything on every channel
everyday - I mainly want to do this to harden my system, for example,
for DVB-T (UK) I have a tuner dedicated to each of the six Muxes, with a
separate tuner for Live TV.

Any help would be much appreciated.

Albert.

In mythfrontend Custom Recording screen, one of the examples (Category
type) does exactly this..

It can be, but you don't get the example. But, since it's a one-time
thing, just do it with mythfrontend.

Also Custom Recording rule. But, rather than a single catch-everything
rule, you probably want to break it down into more manageable chunks.
There are examples in mythfrontend--giving a lot of ways to break it
down (by video source, by callsign, ...).

Thank Mike,

That is so cool!

I've never knew those options even existed as I've always used Mythweb,
and you're write the frontend is the best place to do this as it gives
so must control :)

Thanks,

Albert.

Good luck with that perpetual order for an infinite number of hard disks,
enclosures, cabling, power supplies, etc...

Keep us posted on progress! my Boss is very interested on doing this in Oz -
only need 5 tuners.

Why do you wish to do this? (Just curious).

It will probably overload the scheduler, the "all movie" rule might
already be too much. The scheduler is not optimized for this "simple"
situation.

You can ease the load by creating a video source per capture card
containing only channels from a single transport. If that's still too
much I fear the scheduler has to be modified to skip the in this case
useless conflict resolution.

I'm still having problems getting MythTV to record everything ?, it can
record "groups" of stuff, but even when I try to fool it my saying "
program.title <> 'nova' " it does not work ?, it almost seems that there
is some logic that is preventing really wild searches ?

Also, does anyone know how to remove rules ? there does not seem to be a
delete rule option ?, I know you can make the inactive, but the still
appear in the edit rule list - i.e. they always "appear or look" to be
active, in other words its not obvious which rules are active if you
have a lot ?

Albert.

Use a straightforward rule--such as the examples for "Only on a specific
station" or "Match related callsigns" or "Only channels from a specific
video source" or "Limit by category" or "Category type".

Go into Manage Recordings|Recording Priorities, then find the rule you
want, select it, and set it to Do not record or whatever.

Thanks Mike,

I found that, you can also delete via MythWeb.

Anyway I record "wild card" everything ?

Likely a "Match words in the title" without words (i.e. just the %)
would work. Though you'd likely be better off doing some less-generic
ones first to allow more control over how things record.

The single rule works fine e.g. " program.catogory_type='movie' " works
fine, but
program.title LIKE '%' does not work ?

When I select the "TEST" button it does find all the programs it
"should" record, but when I select record (record at any time on any
channel" and "This recording rule is active" and "Don't match
duplicates" then "Save these settings" it does not add anything to the
Upcoming recordings ?

Is this a bug or a safety feature ?

Albert.

I must have broken something serious, because a how load of recordings
kicked off, almost all of which fail to record anything, but now nothing
is showing in upcoming recordings ?

What could have broken - I have hundreds of Recording Schedules all of
which show up in MythWeb under "Recording Schedules" but nothing in
Upcoming recordings ? - via MythTV or the frontend ?

I've had something similar where my tuner devices will lock-up after some
unspecified length of time (I've had between 2-4 weeks without a reboot before
it locks up). Then because Myth can't access the tuners it decides it can't
use them, then because it has no tuners it can't schedule any recordings so
suddenly my upcoming recordings will be empty. A reboot of the machine
normally fixes it.

Maybe something similar happened when myth tried to record all the channels at
once. Have you ever had all your tuners recording at the same time before?

I did reboot, and it made no difference, I am assuming that some how it
tied the input to the Schedules - which would be a shame as I did not
specify an input (i.e. most are set to any).

I've now deleted all "Schedules".

Next I think I have to force an EPG for all tuners (sources) or wait
till that happens again.

Actually it was a good thing that I had to restore the entire database
setup because all previous records lost the original program meta data -
channel number and name, that was replaced with #1234#, so this time
I've kept the original video sources and created new ones allowing the
existing recordings to show the correct meta data.

Problem is, I think the old EPG data is still being used, so I have to
figure out how to force a EPG rescan :(

We'll I'm build the worlds most advanced MythTV System - I know that's a
huge statement but when I'm finished - its going to be unbelievable.
Some parts are still "secret" as they have never been done before and I
want to be the first.

I've got about 15TB remote storage, the MythTv box boots off the network.

The is how it looks right now, as you can see there is about 45 ltrs of
water in my custom water cooling system - and its heavy :(

That is exactly what I have done, so there should never be a conflict.

I've written a design document for the water cooling table (as I call
it) and it can be found here (just in case you want one) :)

This is a prototype and I'm be having another one made as there are
things I want to change/add.

You know that, I know that but the scheduler doesn't. Even with 4-5
channels per card/video source the scheduler has to find the optimal
distribution of the recordings to the virtual recorders. We know that
the optimal distrubution is to record all recordings from one channel
on one virtual card. The scheduler can't take this shortcut.

You might also find it helps to put in a time limit on the schedule - I
can't remember the exact syntax, but something like 'and start_time <
now() + interval 1 day'. This'll prevent the scheduler wasting it's
time by trying to schedule more than a day in advance. You could even
cut this right down to an hour or two if necessary - if you're recording
absolutely everything then it shouldn't matter.

Well, I assume that's why you must set max recordings per tuner, In fact
I cannot see what choice the scheduler has, given that it will never run
out of Virtual tuners (in my config), it will simply use the next
available free virtual tuner - and it will always be free - unless I'm
missing something!

However, I do think I'll run in to problems in other areas - Watch this
space.

I did see that option but, it never actually clicked with me - Thanks.

I only want everything for testing/finding problems), so your tip will
save me having to delete millions of unwanted crap stuff.

Myth doesn't take to having unused video sources, capture cards, card
inputs too well. The problem with "losing metadata" is that you've
changed the channel ID's when you deleted/re-created video sources (or
channels). You just need to fix the chanid's for the recordings (but I
highly recommend you don't do this yourself as it's much more complex
than you're likely to realize).

In a week or two, I should have the restore script fixed up to fix up
this disconnect caused by changing channel ID's.

That would be really cool because, I have to keep the old sources around
and the old sources where global rather than based on muxes only.

I restored by database and kept the old sources around so the #1234# is
gone, but I still have the old sources around, what's needed is some
script that can correlate all the old channel id (may be the old
sourceid) to the new channel id (which should be the same) using the new
sourceid - assume from my messing around.

Look forward very much to trying your script.

Albert.
