[Q] What image and video viewers are available besides the stock one?

---

Are there any 3D image or video viewers or players available besides using the stock Gallery app?

1. How hard do you think it would be to write one from scratch?
2. Is there a standard Android API for this or is it custom stuff that HTC and LG wrote themselves for their own phones?
3. Does this mean that we won't be able to share 3D images and/or videos with other manufacturer's phones?

Sooo, I take it there's no third party 3D viewing apps (yet)?

I like mVideoPlayer. It will only play native file types though that the stock player would play. But you get swipe to seek, pause on click, auto screen rotation and a lot more. It plays 3d and also can be used to stream videos.

nice, is it free on the market?
