[MPlayer-users] Mplayer wrong colors problem on PXA270

[Eray Öztürk]

​H​
ello,

I have cross compiled mplayer for PXA270 board and with the configuration
below.

I have tried several video types, also with encoded videos with mencoder to
mpeg4 mpeg1 mpeg2 but I could not get a visualization with correct colors.

There are some green areas of pixels on the screen, I've tried with -vf
rgb2bgr, but I got error. Also -vf rgb2bgr=swap has no effect, the colors
are the same.
Also if I do not add -bpp 16 parameter, it shows really mixed picture.
I have another system on the same board, works with nano-x and nxplayer
shows video with correct colors on fbset -g 640 480 640 480 19 -n settings.
I've an strace log of nxplayer (attached)

​I've tried to add some info about my environment.​

​Please help me to resolve color problem.

*​Here is a sample picture of video with wrong colors :​*
