Error when running media-filter Dspace 8

[Wanangwa Nyirenda]

I got the following error when trying to run my media filter to generate a thumbnails for my books.                          

ERROR:Unknon MediaFilter specified (either from command-line or in dspace.cfg): 'PDFThumbnail'

Any help is greatly appreciated,

Wanangwa.

Hi Wanangwa,

This error could be caused by some missing or incorrect media filter settings.   First, double check that you have enabled the media filters you want to use (more details in the configuration reference).  For example, to use the "PDFBox JPEG Thumbnail" filter you would check that dspace.cfg includes the lines:

filter.plugins = PDFBox JPEG Thumbnail

and
plugin.named.org.dspace.app.mediafilter.FormatFilter = org.dspace.app.mediafilter.PDFBoxThumbnail = PDFBox JPEG Thumbnail

Second, if you are running the command with -p to apply limited filters, you could check that the plugin name matches your config:

[dspace]/bin/dspace filter-media -p "PDFBox JPEG Thumbnail"

Best,
Lia
