Quote:On my test DVD ISO (it's a rip of the Hitchhikers Guide to the Galaxy - BBC version - Extras disc, mpeg2/ac3) I played a couple of the available extras and whenever the extra had finished playing and returned to the menu, the menu would now flicker several times a second with a green overlay. Stopping and restarting playback with dvdplayer still had the green flicker, only killing xbmc.bin would fixed it but it's reproducible. Flicker is only a problem with dvdplayer - no green flicker with omxplayer.Yes. Initially the software decoded menu displays correctly. Once you have played some of the hardware decoded DVD, the next software decoded menu flickers green.
I don't know why. Possibly the hardware decode is getting the render queue out of sync compared to what the software decoder expects.
Quote:Also the codec information is a little odd - when selecting "DVDPlayer" in "Play Using...", and having selected to play one of the extras, the codec info initially shows dc:libmpeg2 at the start of playback (maybe being used for the menu?) then switches to dc:omx-mpeg2 for the remaining video playback. Should it be showing dc:omx-mpeg2 when using dvdplayer?Yes, omx-mpeg2 is the name of the openmax hardware codec.
