Re: [Tracker] How much writeback support is there (planned?)

[Ivan Frade <ivan frade gmail com>]

Hi Daniel,

 Writeback is a mine-field. Conceptually because modifying files in the filesystem feels evil, technically because the combinational explosion of formats for content and metadata. 

 That is the reason we implemented it for very very very specific use cases and are not very enthusiastic about extending it. If you feel is useful for you and want to improve it, you can suggest patches. As long as its functionality is optional and can be enabled/disabled in compilation time, there is no problem in supporting more formats. Just be aware of the pandora's box you are opening :)

 In the case of videos, you need to "copy" the whole file to introduce metadata. IIRC you cannot write just a bunch of bytes in the header. Copying a whole 1GB file can be very painful and slow...

 Regards,

Ivan

Hello Daniel,

as far as I know there is know writeback support for videos. We use
taglib to writeback to most audio formats though. I don't know if there
is a sort of taglib for videos, if there is implementing writeback for
video files shouldn't be too hard.

Judging from the state of user-land tools described at http://ubuntuforums.org/showthread.php?t=1193808 ; I might be waiting a while.

Alternatives then: What, if any label properties does tracker tend to render for videos?
Is it as simple as adding a dc:title/nie:title to an nmm:Video?
