Forum Post: OSD issue ON DM8127?

Hello,there.

We are developing our product on dm8127 with v3.8RDK.

Now I'm facing a problem ,OSD problem.

We need to display date,channel,osd text on screen.I prepare these data and called SWOSD_setBmpWinPrm ...... finally called  SWOSD_blendFrames。

I already have drawed 16*8 or 32*16 text on screen(1080P),it worked well.BUT,if i drawed 64*32  with same text(almost 80 or 90 chars I guess), the routine SWOSD_blendFrames returned fail.reduce to 60 chars and it will be OK.

I don't know the reason why it failed,the failed means what?

PLEASE HELP,THANKS.
