This function is included in latest programme about dm365 ipnc , in the directory \Private\ipnc_app_dm365_priv_1.0.0\av_capture\framework\alg\src\algswosd.c.

I really don't konw how the function work. In a function called " int ALG_swosdDrawLine(ALG_SwosdRunPrm *bufInfo, ALG_SwosdLineInfo *lineInfo)" ,

two parameters are used -- bufInfo->videoOffsetH and bufInfo->videoOffsetV , can everybody tell me what these two parametes are?

Thank you !!!!!!!!!

mmm, not really familiar with dm365 ipnc software since this is primarily supported by the third parties that sell these solutions. Have you tried contacting them?

Sorry to ask you again . I want to use osd to draw rectangles,and now osd can draw ,but the rectangles are always flickering . Can you tell me the general causes of this problem??

Thank U !!!!!!!

flickering could be cuased by mis-aligment of video frame data with vertical blanking data; but this is just one cause. does the screen stop blinking when say the video window is disabled? What about if OSD is disabled, does video window flicker?

Yes , you are right , I also found that the problem is caused by mis-aligment of video frame data with vertical blanking data. I will try to solute it , Thank U !

ps: when the osd is disabled ,the video window doesn't flicker .
