[jira] [Commented] (TIKA-939) Windows Media Video file detected as
Windows Media Audio
Posted by "Nick Burch (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TIKA-939?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13294527#comment-13294527 ]
Nick Burch commented on TIKA-939:
---------------------------------
WMA and WMV use the same container format (ASF), so detecting them only based on mime magic is tricky to do. Ideally, we want a container aware detector for these kinds of formats, much as we already do for things like ZIP, OLE2 and Ogg.
In the absence of a proper ASF container format aware detector, we have to try to fudge things based on looking for magic strings in a file with the ASF magic bytes at the front. There's alas not an obvious serious of bytes we can look for that conclusively says "this is a video", so for now we just look for the video codec names in the first 8kb. Your file used a different codec, so wasn't found. The audio codec chosen was found, so Tika assumed it was audio.
I've added the string for this in r1349906, so detection now works properly for your file. Longer term, we do need someone to do a proper ASF aware detector.
