Ever since the announcement of the N9′s DLNA support people were looking for a feature called DLNA +PU+ which allows you to send media files to e.g. DLNA-capable TVs without enabling content sharing on your device, giving you a really fine-grained control about what and where to share to.
PushUp is a small utility that hooks into the N9′s sharing framework and allows to you push an image or a video to your TV just like you would with Bluetooth or NFC. Get it on this site (or later through the Nokia Store).
It is an offspring of my Korva project, a D-Bus specification and its implementation for media pushing. While still work-in-progress, it’s already fully functional.
Edit: I had to update the package because the icon was missing and cancelling the device selector was broken.
Edit2: Updated again since it was broken on PR < 1.2.
