Nick Burch commented on TIKA-3023:
----------------------------------
The FFMpeg project have some sample SGI Movie files at
[https://samples.ffmpeg.org/sgi/]
Based on looking at a few, I think MOVI followed by a very low or high byte
ought to be a safe check. I've added that in {{0d259bc8b}}
> Text files starting with MOVI are detected as X-SGI-Movie
> ---------------------------------------------------------
>
> Key: TIKA-3023
> URL: https://issues.apache.org/jira/browse/TIKA-3023
> Project: Tika
> Issue Type: Bug
> Affects Versions: 1.23
> Environment: Issue recreated on
> Windows 10 Professional 64bit running the runnable Jar
> Ubuntu 16.04.6 LTS running Tika-Python
> Reporter: Steve
> Priority: Minor
> Attachments: capitalmovie.txt
>
>
> 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
> [https://reposcope.com/mimetype/video/x-sgi-movie]
>
> 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.
