swosdLink_tsk.c: SWOSD_imxCreate(strId, isTiled[strId] ,lineOffsets[strId] ) ==0 : failed !!!

Hi!

I'm working customized DM385 platform

My usecase is like that 

CaptureLink  --- SWOSDLink --- Displaylink

But when  swosd created, Print the following information：

StreamID is 0
[m3vpss ] staticPrm.isInterlaced = 0
[m3vpss ] staticPrm.videoLineOffset[0] = 2208
[m3vpss ] staticPrm.videoLineOffset[1] = 2208
[m3vpss ] [SWOSD] SWOSD_imxCreate for stream 0
[m3vpss ] SWOSD Open failed for stream#0 !!!!!!!
[m3vpss ] 44953: Assertion @ Line: 217 in links_m3vpss/swosd/swosdLink_tsk.c: SWOSD_imxCreate(strId, isTiled[strId] ,lineOffsets[strId] ) ==0 : failed !!!
