DearAll, I am using DVRRDK3.0 with DM8168EVM. Because no capture module, I create my own chains with NullSrcLink in order to test dm8168 OSD function and my chains is run normally.the following is about my chains:
nullsrclink -->....->dsp(osd) --> ... --> enclink-->ipcBit( h264)
After run this chains, I can get the h264 video data, then i playback it with player(BaoFengPlayer).
at last, I find that the osd is overlay successfully but also has some questions seemingly.Mainly from the following three aspects:
NOTE:my chains only overlay one osd.
1. to overlay date "2012-06-15 Fri"(startX=150, startY=300), but the real result is the following image:
2. with "1", I continue to disable this osd, but i find that the saved data is the same with above image.
3. I restart the chains with different osd overlay position(startX=500, startY=500) and find that the original is also exit and the new osd is incorrect!, see the following image:
With question "3", after some test, i find that only if power down 8168, the last osd overlay will remove.
The section code of configure osd:

SO, is it question?or is it due to NullSrcLink?Why?
Please give me some suggestions, ThankX!!!
