Is there a way to change the resolution of the player to have a full frame image on the paperwhite ?
thanks for your help!

You would also need to change the video transcoder (raw2gmv) to the new resolution, and encode some videos in that resolution. They are pre-dithered by the transcoder program, and the player just spits the video lines onto the display.
Your larger videos would probably work as-is on the smaller 800x600 kindles (with the larger resolution video player), but only part of the image would be visible. Also a possibility that it could throw an error if the last line extends beyond the end of the framebuffer, but newer kindles have really large framebuffers, so unlikely.
Because the GMV video format contains no metadata to describe resolution, the 800x600 resolution (common to all kindles at the time of its development) was the default value.
For the new version (in progress) I plan to add metadata file headers, so I can support multiple resolutions, in addition to interleaved sound, and I will call them GMM (geekmaster multimedia) files. The new player will also support legacy GMV files, if no file header is found.
