Update of /cvsroot/datatype/omx/common
In directory cvs01.internal.helixcommunity.org:/tmp/cvs-serv24967

Modified Files:
      Tag: hxclient_3_6_5_atlas
	CFrameObj.cpp 
Log Message:
Synopsis: On 8650a platform, some dropped frames are shown on screen before seek \
operation complete.

Overview: For each frame, video site call postBuffer(offset) to let it shown on \
screen. After this, surface flinger has some kind of connection with this frame \
buffer. During seek operation, Helix do not call postBuffer before desired seek \
point. However, we can see some dropped frames by Helix shown on screen. In order to \
avoid this issue, change to hold 1 frame buffer while doing seek operation. Change \
IHXVideoSurface interface to add a api, to let video site know when it is time to \
seek(OnPreSeek). In CMiniAndroidSurface::OnPreSeek, flag the last frame which is \
shown on screen. After that, when flush begin in OMX wrapper, it will check which \
frame is being shown on screen and do not return it back to OMX decoder
