Displaying the file name (but not the file location) is easy. From a
recording, I twice gives you a lot of information about a recording,
including its file name (the "basename") It is not really possible to
copy the file name from there though - mythfrontend turns the mouse
cursor off. In scripts attached to MythTV events, you can pass the
basename to the script using one of the builtin parameters.

I normally just do a database query to find a recording file:

MariaDB [mythconverg]> select
chanid,nzt(starttime),title,subtitle,left(description,20),season,episode,seriesid,programid,filesize/1024/1024/1024
as filesize,basename from recorded where title like '%schindler%'
order by starttime;
+--------+---------------------+------------------------------------------+----------+----------------------+--------+---------+-----------+-----------+----------------+-------------------------+
| chanid | nzt(starttime) | title | subtitle | left(description,20) | season | episode | seriesid | programid | filesize | basename |
+--------+---------------------+------------------------------------------+----------+----------------------+--------+---------+-----------+-----------+----------------+-------------------------+
| 10073 | 2021-01-27 22:43:00 | Oskar Schindler: The Man Behind The List | | The amazing story of | 0 | 0 | 128075076 | | 1.577273443341 | 10073_20210127094300.ts |
+--------+---------------------+------------------------------------------+----------+----------------------+--------+---------+-----------+-----------+----------------+-------------------------+
1 row in set (0.071 sec)

Then to find the file location, I use locate:

root@mypvr:~# locate 10073_20210127094300.ts
/mnt/rec1/recordings/10073_20210127094300.ts
/mnt/rec1/recordings/10073_20210127094300.ts.png

That only works if the recording is a day or so old - the location
database only gets updated once a day. You can force it to be updated
manually:

sudo updatedb

but that takes a while as it scans all the partitions mounted on your
system.

I believe there is some Python on the wiki that has an example of how
to find a recording file using the storage directories in the
database. I have never used it, as in my MythTV Python programs I am
moving lots of recording files, so I pre-build a database table giving
all the locations of the recordings before I start moving files. See
my mythsgu program if you want to do something like that:

Thank you Stephen. I had seen your use of 'locate' earlier but hadn't
tried it; I thought it looked like overkill, but maybe it learns over
time. One of my scripts uses parts of dvbradioexport.pl, from the
wiki, to unpick the Storage Groups; again, my integration lacks polish,
and would need a re-work for more general use. The second 'info' screen
only provides 'Default' for the SG, which seems unhelpful. I'll see if
I can make anything more of the API stuff.

You can use mythlink.pl (https://www.mythtv.org/wiki/Mythlink.pl ) to
create links with useful/recognizable/customized-for-your-scripts names,
then use those useful names to get the full path to the actual recording
file with:

readlink <link_name>

Last time I tried to get Mythlink.pl working, I failed. If someone has
this working, I like to learn.

Yes, thanks Mike. Having recently recommended mythlink and cp -L here
I should have made that connection. In GUI mode I would probably read
the link destination from the file manager screen, or copy from its
'Properties' popup, but mythlink + readlink looks as if it could be more
scriptable. I'll look at the mythlink wiki again. :-)

There seems to be no need to do any new scripting. In a Plasma (KDE)
desktop, this works:

Run mythlink.pl to put links into a folder.

Open that folder with a file manager; I still use konqueror.
Right-click on the recording to be processed and select 'Properties'.
Right click on the contents of the 'Points To:' box, Select All, and Copy.

In a konsole (terminal) tab, recall (Ctrl/R or UpArrow) a command line
similar to the one you want. Erase the old file details and Paste in
the ones from the link.

Run the new command.

Any details on what's not working (error messages, behavior, ...)?

In that thread, I was about to recommend mythlink and cp -L (which is
what I do to copy recordings to my laptop) until I saw you already had. :)

That works, but needs mouse gymnastics. Here's an alternative.

For some time I have used a lightly customised MythCenter-wide theme,
not always kept fully compatible with the current version. Now master
has a bigger update and I had another look.

I think I can get what I want if I make a simple change in
recordings-ui.xml, replacing

{{{

<template>%startdate%%| startyear%, %starttime% </template>

by

<template>%recstartdate%%| startyear%, %recstarttime% - %recendtime%
%recordedid% </template>

}}}

although the date/year sequence has often given me slightly strange
results that probably depend on my specified short-date format.

It's easy to tweak this and I will experiment some more, but I wonder if
it, or at least the inclusion of the RecordedId, might be considered as
an official change?

This works for me now. It's a little cramped but fits into the space
allocated.
