[MPlayer-users] Request for Bloom effect in Video Output

Why not? - Bloom - it is effect that simulates moving signal from cells in eyes facets, exposed to bright light, to nearby cells. HDR - it simply more wide color space - not [ 0, 1 ], but [ 0, max float ] - it then tone mapped to [ 0, 1 ] - so why not to implement it on [ 0, 1 ] color space, instead of [ 0, max float ] - ofcourse the result will be not so precise as with HDR data, but it will work.

Why not to use FBOs in OpenGL - they are portable.

I mean some kind of bright lighting corona around windows in dark areas in this film. It was, as far as I remember, in the scene of pursuit on some kind of plant or fabric. I don't remember such effects in other films - maybe here is used some special camera or it is enhanced on computer - I'm not specialist in this area - but it looks very good. So if there will be ability to add this effect in realtime to all films - it will be very good - there will be ability to enhance realism of lighting.
