DLNA Posts
I have a lot of movies I ripped from my DVDs over the years. In the past we used VLC to stream videos to our TV, but our new TV uses DLNA. The issue is DLNA uses the metadata encoded in the file, so all of my movies were showing up as DVD_VIDEO, which is what the title tag defaulted to when I encoded them.
There is a CLI tool that can be used to work with image and video metadata, named exiftool. To get the title tag for a file, use exiftool -title filename. This is the tag DLNA is using to display the title for your videos. You can uses -title= to update the title tag. What I did was use a shortcut to automatically set the title as the filename: exiftool "-Title<FileName" *.m4v. You can also use a folder name instead of a file and update all of the files in that folder. If you want to process files in multiple folders under one path, add the -r flag to the command. One side-effect of this tool is it creates a copy, in case of a write error updating the data. You can override this by adding -overwrite_original to the command.
Example:
exiftool -r "-Title<FileName" -overwrite_original ./
