Usage Notes for the 'rivendell_filter' Import Script.
|
|
|
|
Rivendell_filter is a script designed to be used to import existing audio
|
|
and meta-data from another Rivendell system. It is invoked as follows:
|
|
|
|
USAGE
|
|
|
|
rivendell_filter -h <hostname> -u <username> -p <password> -A <audio-dir>
|
|
-g <default-group> -s <start-cartnum> -e <end-cartnum>
|
|
Where:
|
|
<hostname> = The MySQL hostname of the source Rivendell database.
|
|
|
|
<username> = The MySQL username of the source Rivendell database.
|
|
|
|
<password> = The MySQL password of the source Rivendell database.
|
|
|
|
<audio-dir> = The name of the directory containing the source
|
|
Rivendell audio files.
|
|
|
|
<default-group> = The name of the group in which to place carts
|
|
belonging to a source Group for which there
|
|
is no corresponding destination Group.
|
|
|
|
<start-cartnum> = The first cart in the range of those to be transferred.
|
|
|
|
<end-cartnum> = The last cart in the range of those to be trasnferred.
|
|
|
|
OVERVIEW
|
|
In order transfer carts from an external Rivendell system, proceed as
|
|
follows:
|
|
|
|
1) CREATE RIVENDELL GROUPS
|
|
In RDAdmin->ManageGroups, create a Group to correspond to each Rivendell
|
|
Group that exists in the library to be imported, and an additional
|
|
group to catch any carts that may not have a corresponding Group.
|
|
|
|
2) LOCATE THE EXTERNAL RIVENDELL DATABASE AND AUDIO FILES
|
|
The directory containing the audio files can be mounted from a remote
|
|
system if needs be. Read-only access is adequate (and in fact recommended),
|
|
as the script does not modify these items in any way.
|
|
|
|
3) VERIFY AVAILABLE DISK SPACE
|
|
Verify that enough disk space is available in the '/var/snd/'
|
|
directory of the destination system to accomodate the audio to be
|
|
imported. You should have at least the amount of space currently occupied
|
|
by the source files, plus 5 percent additional.
|
|
|
|
4) INVOKE SCRIPT
|
|
Start up the script, as described in the USAGE section above. The
|
|
script will print progress reports as it proceeds, or notify you of
|
|
error conditions as required.
|
|
|
|
WARNING
|
|
If a cart from the source system has the same number as one one the
|
|
destination, the destination cart (data and *all* audio) will be overwritten!
|
|
|
|
NOTE ON AUDIO PROCESSING
|
|
Rivendell_filter does not alter or reencode the audio sample data in any
|
|
way, and thus does *not* incurr any generation or transcoding loss of
|
|
quality. At the same time, this means that the incoming audio will be
|
|
brought into the new Rivendell system *exactly* as it exists in the
|
|
source system, with all parameters (e.g. sample rate, bit rate, level,
|
|
etc) unaltered. If you need to alter one or more of these parameters as
|
|
part of the import process, we suggest you use the RDImport script
|
|
instead.
|
|
|
|
NOTE ON GROUP ASSIGNMENTS
|
|
WARNING: Rivendell_filter makes no attempt to enforce group numbering rules!
|
|
If a group to which a given source cart belongs exists on the destination
|
|
system, the cart will be placed in that group, regardless of numbering rules.
