I work in an educational college, and we have moodle 3.3.5
We are having a number of
issues at the moment with files not converting properly when in on screen
marking view. The file will preview blank, and sometimes it will say something along
the lines of ‘generating file’.
We understand that the issue may be to do with our file convertor - we currently use Unoconv.
It has been suggested that we switch to Google Convertor, however we don’t feel comfortable moving to Google Convertor, as our college policy is to use Microsoft and for data protection reasons.
First question is, is there an alternative to Google Convertor? Is there a Microsoft version for instance?
question is, is this issue purely down to the file convertor? Or may there be
something else causing the problem?
I don't know. But my experience is that unoconv is pretty much useless and Google docs works near perfectly.
I'm not sure what Microsoft has to do with this. You're not really comparing like with like I think.
The big issue with unoconv we experienced is that the conversion in Libre Office is less than stable. It hangs on very complex documents (particularly if they have lots of images). On top of that, the whole thing is single-threaded, so if it hangs that's it. No more conversions until you restart it.
Howard.. you mean restarting the unoconv service correct?
Jonathan, I will offer an alternative idea just to provide some additional ideas of how this problem might be solved.
In my own case, I never use the converter for grading uploaded student files. Instead, I always download the submitted files and "grade" offline. (Of course, I download the grading worksheet for the assignment." I find it much faster to open student files from my computer than to try to grade with the converter. If you really want to mark up a file, there are many ways to do this with applications on your computer. Moodle provides an easy way to provide instructor comments in the grading worksheet, or if needed, you can pass back files to the students.
I know that in another LMS they refer to their internal "markup" system as "speed grader" but I find it to be "much slower grader" or "You must be kidding?"
