Part of the work is actually done inside mythfrontend inside
TV::ToggleRecord() in libmythtv.
To toggle record ON for a LiveTV program, we do the following:
- set the recorded.autoexpire column to the default autoexpire
- set the recorded.recgroup column to 'Default'
To toggle record OFF for a LiveTV program, we do the following:
- set the recorded.autoexpire column to 10000 (this is a const int in
- set the recorded.recgroup column to 'LiveTV'
When the AutoExpirer runs every few minutes to expire LiveTV programs,
it looks for recorded.recgroup == 'LiveTV'. The autoexpirer == 10000
puts these LiveTV programs before any other programs in the expire
list when the expirer runs checking to see if it needs to free up
disk space by deleting recordings.
If you want to verify how we set the autoexpire and recgroup columns, you
can look at libs/libmythtv/programinfo.cpp at the following methods:
