I need to read metadata from Android video files. I looked at the tags available through MediaStore.Video.VideoColumns and android. media.MediaMetadataRetriever . However, both of them do not give me access to some additional tags that can be accessed by a tool such as ExifTool by Phil Harvey .
I’m most interested in the Camera Make / Model, Compressor ID tags, but I’d also like to know how to access the other tags.
Are there any APIs in android for reading these additional tags, or am I looking for a specific file format, my own meta-analysis of metadata?
Here's the output created by ExifTool for the video shot with the iPhone camera:
