CC 708 Tracks in MediaConch Broken?

Closed this issue · 2 comments

jsciame commented

I'm attempting to run MediaConch against QuickTime MOV files with embedded 608 and 708 closed captions. The MediaConch is not identifying the 608 or 708 tracks.

Running MediaInfo outside of MediaConch.

MediaConch GUI 18.03.2.20211214
MediaInfo Command line, MediaInfoLib - v21.09

When I import the file into policy to create a policy from file, MediaConch does not show the text tracks. I'm happy to send the sample file if you need it, but I'm attaching the full MediaInfo and MediaConch Reports.

I tried the Windows GUI and CLI and can get the 608/708 from a MOV with c708 codecid, and this is the output from MediaConch Command Line Interface 18.03.2.20220117 Windows:
608_in_c708.MediaInfo.xml.txt

And it works with the policy:
608_in_c708.Policy.xml.txt

Maybe a specific issue with your file.
Please try the latest version of the Online policy checker (it is up to date), if still the issue I need the specific file.

For reference with my file I have:

<?xml version="1.0" encoding="UTF-8"?>

Reproduced with a HTTP link.
Fixed by removing a specific configuration of MediaInfo library in MediaConch, better to use MediaInfo library defaults.
