Fail harder for fractional frame rates? #106

Open matmat opened 7 months ago

matmat commented 7 months ago

I received this, clearly unplayable DCP. I don't know about any system supporting fractional frame rates for DCP playback. Maybe fail harder in a more clear way?

Excerpt from log (do tell me if you need the whole thing):

Have you tried playback? Does it actually fail on anything other than a DSP100?

matmat commented 7 months ago

On a Cat745/DSS200 system version 4.9.5 (2) it does not even ingest.

From the logs:

Thanks. (I was wondering because all those systems should be able to play the occasional olden MPEG DCP with 24000/1001 rate). Actually can't find anything specific wrt JPEG2000 frame rates in the Interop docs.

Yes, better reporting and Error class needed.

Is there a chance you could send me the package minus video/audio assets? Would like to look into those timecode RangeErrors.

matmat commented 7 months ago

Of course! Sent you an email.
