[jira] [Commented] (TIKA-3023) Text files starting with MOVI are detected as X-SGI-Movie

Tim Allison commented on TIKA-3023:
-----------------------------------

I regret that I know nothing about this format. 

TRID requires only "MOVI": [http://file-extension.net/seeker/file_extension_SGI]

I couldn't quickly find a signature in Pronom.

{{file}} requires only "MOVI"

 

From the files linked here: [http://fileformats.archiveteam.org/wiki/SGI_movie], it looks like they all start with "MOVI\u0000".  

 

Any objections to adding a 0x00 after MOVI?

> If a plaintext file starts with "MOVI" Tika labels it as an SGI Movie.
> The hex conversion for MOVI is 4D 4F 56 49 which is the same as the header for the SGI Movie file format

> This SGI format isn't supported so any information from a text file starting like this would be lost. I've attached a simple file that should recreate the problem.
