I've just heard about Miro, an open source media player, and it looks like this app could fill my needs for videos much like calibre does for ebooks.
Miro is a video player for Windows, Linux, and OSX. Like calibre, Miro will play multiple formats and it even supports conversion to and from a number of formats.
I heard about it on Twitter because of a new feature that Miro added last week. Not only can you use Miro to watch and manage your video collection, but you can now use it to transfer videos to the Kindle Fire. Given the conversion abilities, it also supports pretty much all Android devices, the iPad, and most other mobile devices.
Now, there are a number of proprietary alternatives to Miro. For example, I use Real Player to manage most of the videos I've downloaded. I don't much like the app, but until now I had not wanted to take the effort to convert from FLV. Miro can do that for me just fine.
But for the most part, I've never used a video library app before. I always just managed my collection by moving and opening the files manually. It's nice not to have to bother with that anymore. I'm also looking for ward to using Miro to transfer the files to the various Android tablets I get my hands on. I don't have a Kindle Fire anymore, but this app will work just as well with just about anything I come across.
