> Canon CR3: emit the embedded JPEG preview as THUMBNAIL
> ------------------------------------------------------
>
> Key: TIKA-5042
> URL: https://issues.apache.org/jira/browse/TIKA-5042
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Reporter: Dominik Schmidt
> Priority: Major
>
> CR3 files are detected as {{image/x-canon-cr3}} (TIKA-3991), but unlike the
> TIFF-based raws (TIKA-4824, TIKA-4980) they yield no preview: CR3 is an ISO
> base media file, so MP4Parser reads it and emits nothing, and
> {{/unpack/preset/thumbnail}} answers 204.
> The previews are in Canon {{uuid}} boxes:
> * a JPEG preview of 1620x1080 in the top-level {{uuid}} box
> {{eaf42b5e-1c98-4b88-b9fb-b7dc406e4d16}}, as a {{PRVW}} record (the JPEG
> starts 20 bytes after the {{PRVW}} tag)
> * a 160x120 JPEG thumbnail ({{THMB}}) inside the {{uuid}} box
> {{85c0b687-820f-11e0-8111-f4ce462b6a48}} in {{moov}}
> Emitting the {{PRVW}} JPEG as {{THUMBNAIL}} (and {{THMB}} as {{INLINE}}, as
> the TIFF-based raws do with smaller previews) would give CR3 a preview.
> Checked with the CC0 sample "Canon - EOS R6 - 3:2.CR3" from raw.pixls.us.
