Youtube/Flash YUV

Post by Johny-115 » Fri Mar 18, 2011 3:57 pm

- Ive read that Flash Player converts YUV video to RGB for playback ... yet when i upload videos they are always displayed as greyish YUV .... how can i fix that ?

this is not my video, dunno what its about ... but its exactly my case ... my videos looks like bottom video YUV with no conversion, while on KMPLayer etc they look like top one

- also i noticed my exact same files actually work on Vimeo (look as top one)

example of my encode:
