Oldrecorded and recorded entries do not match when preroll used

[red321]

When preroll is set, oldrecorded.startime is the programme start, and recorded.starttime and the filename is the recording starttime including preroll. When myth.rebuilddatabase searches oldrecorded for title and description, it fails as the filename and oldrecorded don't match.

Replying to red321:

When I re-read this I realised it wasn't very well explained.

The problem is that myth.rebuilddatabase uses the orphan files filename to rebuild the database entry. The orphaned filename is by default chanid_(starttime+prerolloffset).mpg. The chanid and (starttime+prerolloffset) are used to find entries in oldrecorded. However as oldrecorded is populated with chanid and starttime (without preroll), unless preroll is 0, then there are no matches.

The solution is either to use startime for all entries (filename, recorded, oldrecorded) or always use actual startime which includes preroll.

This is a problem with myth.rebuilddatabase.pl and it needs to be fixed there.

The mixing of starttime/restartts/progstart etc is a regrettable source of confusion, but the changes required to fix it would be far harder than just working around it this in the script.

Feature request without patch.

FWIW, the myth.rebuilddatabase.pl script will be obsoleted as soon as I've added its functionality to mythbackend and mythfrontend. I plan to do this after the 0.23 release.
