[COLOR=#000000][FONT=verdana]I have a video (MP4) I load using Flash (AS3). I load the video locally using NetStream object, and when I sample the pixels - they are a bit ‘off’.[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]To test this - I prepared a video with 100 frames of only red pixels (all the pixels are 0xFF0000).[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]When I load this video using flash’s NetStream class, and then use ‘getPixel’ to test the pixel color of a frame shown, I get that the pixel color is:[/FONT][/COLOR] [LIST] [_]R = 255 [_]G = 12 [\*]B = 0 [/LIST] [COLOR=#000000][FONT=verdana]Why is the ‘green’ value not 0 ??[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]Also, when I load a video that contains only green frames, the value of the pixel after Flash loaded it is :[/FONT][/COLOR] [LIST] [_]R = 0 [_]G = 232 [\*]B = 0 [/LIST] [COLOR=#000000][FONT=verdana]Only the blue video frame are correct (0,0,255).[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]Why is this ? can it be that flash is decoded the video and performing some processing on it that changes the colors ?[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]I need the colors to be exact, because I sample different pixels to detect stuff, and I need the colors to be shown exactly like they really are in the video ![/FONT][/COLOR] [COLOR=#000000][FONT=verdana]Thanks.[/FONT][/COLOR]
