Hi, I'm playing a stream of raw RGB images. MPlayer output (-v) contains the following lines: *** [scale] Exporting mp_image_t, 1024x768x24bpp RGB packed, 2359296 bytes *** [mirror] Allocating mp_image_t, 1024x768x12bpp YUV planar, 1179648 bytes *** [bmovl] Allocating mp_image_t, 1024x768x12bpp YUV planar, 1179648 bytes *** [vo] Allocating mp_image_t, 1024x768x12bpp YUV planar, 1179648 bytes For the mirror filter it may make little difference, but wouldn't the bmovl filter work better on RGB than on YUV? I'm a bit confused that even -vo X11 seems to prefer YUV, it has to be converted to RGB to be displayed, no? If some -vo could handle RGB, would the filters be running on RGB? On some filters I think that might improve performance, and the scale filter wouldn't be necessary at all. Thanks for any input :-) Greets, Kiste
