Certain codecs (mostly third-party codecs) use hardware overlay (or hardware acceleration) for video rendering. This situation will result in Splashtop Streamer being unable to capture the desktop screen correctly through the Microsoft® Windows® screen-capture APIs. In this case, you may try to change the setting of the codecs.
- In Media Player Classic, enabling VMR-7 (renderless) or VMR-9 (renderless) in the Playback Output options should help. See this topic: http://wiki.digital-digest.com/index.php/Media_Player_Classic:_Hints_and_Tips for detailed information.
- In Media Player, Tools --> Performance tab --> Advanced button --> uncheck Use Overlays under Video Acceleration in ver9 (XP). Or uncheck Use Overlays under DVD Video in ver11(Vista/Win7).
- In VLC player, go to Tools --> Preferences --> Video, and uncheck Accelerate Video Output. Then restart VLC.
- In GOM player, press F5 to open the Setup window. In Video/Output --> select VMR7 or VMR9.
Or, if you are using other media players, you may alternatively try to turn off Direct X™ rendering features, or disable hardware acceleration.
