[mythtv] [PATCH]Shouldn't MythVideo store filenames relative to VideoStartupDir?

[Neale Swinnerton]

Hi,

I've been having a problem with MythVideo and the way it stores 
filenames in the Database.

I have 1 machine that acts as a nfs server and another frontend that 
mounts the Video directory from that nfs server. On the nfs server I 
occasionally run a frontend that accesses the disk 'direct' (and via a 
different path)

Although MythVideo allows you to specify a VideoStartupDir, the 
filenames stored in videometadata are absolute, so if I do a video scan 
on one machine I can't browse them on the other.

The attached patch makes VideoScan store the paths relative to 
VideoStartupDir. It also tweaks the playVideo methods to prepend 
VideoStartupDir before invoking the player.

The existing code seems to have some support for multiple 
VideoStartupDirs, separated by ':', I've removed this, since it would 
then mean each frontend would need to search for the appropriate 
VideoStartupDir, which seemed odd to me.

I guess this change will break any existing data in the videometadata, 
but it would be straightforward to tweak that data to fix it.

Anyone have any thoughts on this?

Neale.

PS: My C++ is rusty and Qt non-existent, so feel free to shoot holes in 
the patch.
