VLC: 

main video output : using chroma module "i420_yuy2_mmx"

MediaPlayer: 

MediaTrackVideoSupplier::_SwitchFormat() - preferred color space: B_YUV420
resolve_colorspace: gfx_conv_yuv420p_rgba32_sse2
MediaTrackVideoSupplier::_SwitchFormat() -  codec changed colorspace of decoded format (B_YUV420 -> B_RGB32)!

Is it possible to check with MediaPlayer without overlay?

comment:3 by luroh, 13 years ago

MediaPlayer without overlay enabled plays bunny-rr.ogv without any discoloration in hrev43904, gcc2. Output: 

MediaTrackVideoSupplier::_SwitchFormat() - preferred color space: B_YUV420
resolve_colorspace: gfx_conv_yuv420p_rgba32_sse2
MediaTrackVideoSupplier::_SwitchFormat() -  codec changed colorspace of decoded format (B_YUV420 -> B_RGB32)!

Replying to luroh:

i've been suspecting an overlay problem in the mediaplayer for a while now,as i had the same problem with another model(can't remember the exact model some 109xx?)playing another file,download the file localy if you need to test with it. ​http://www.google.com/url?sa=t&rct=j&q=haiku%20screencast%20ssh&source=web&cd=1&ved=0CCIQtwIwAA&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3D0n09nuJdkbE&ei=5gx3T53uDoj80QWujamQDQ&usg=AFQjCNGQdve6Teym95EVxzosq8Aq1PSGCA&cad=rja ,and in order to play correctly you need to disable overlay as reported by luroh,and it's also very likely that this is a dupe of #5758. this ticket is not a driver/driver-only issue.
