[OC 10] Manual upload no longer works for Camtasia/*.trec files

[K. S.]

Hi all,

it seems like we can no longer upload Camtasia/*trec files with Opencast 10. The workflow always fails at the "inspect" step with the folowing error message (I censored the URL and Path):

The same happens both on our server and the test instance at https://stable.opencast.org
       

ffmpeg doesn't seem to be the problem, at least using ffprobe everything looks good:

It seems to me that the "trec" file suffix is missing in MimeType.xml and Opencast does not recognize the filetype properly. Or am I missing something, is there maybe a way to add custom Mimetype definitions somewhere?

Hi Katrin,

You say 'no longer', did this work previously?  Looking at the history of the MimeType xml file I don't see trec suffixes listed, but that doesn't mean the logic didn't previously ignore the suffix :)

Adding it to the relevant file and rebuilding the module would definitely fix the issue.  Unfortunately, I don't see an obvious way to do this *without* rebuilding that module.  Try renaming the file?  I imagine ffmpeg won't actually care.

I'm wondering if just renaming it to .mp4 would also solve the problem?

Hi Lars and Greg,

renaming the file to *.mp4 indeed solves the problem. I guess the file ending is only really used to determine whether it is a video/audio/other file.

Considering that the relevant code seemingly has not been altered in 4ish years, I also wonder how this has ever worked, but it definitely did.

Should I create a ticket for the Mimetype?

Thanks for the help!
Katrin

[Greg Logan]

Hi Katrin,

Sure.  I feel like there are probably two issues here: camtasia/trec support, and general handling with regards to unknown file types.  An issue would help us discuss it and then hopefully get a better resolution than just renaming the files.
