Hi,
I am using EZ-SDK with DM8168. My requirement is to add some Image(logo) or date on the video.I think OSD is supported with EZSDK but i can't find any demo example so that i can refer how it can be done. Since I am new to this filed any suggestions/links on how to approach the requiremnt would be appreciated .

Thanks

    HI,

    OSD is supported in EZSDK.

    Refer here: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/p/203305/772455

    You could also use gstreamer with element textoverlay to adds text strings on top of a video buffer.

    Hi Vivek,

    Thanks for the reply, I referred to the link which you have provided but didn't find any steps or method for OSD Usage. I am using gstreamer for capture and display. My requirement is to add text as well as logo on to my captured video. Adding text could be done using textoverlay element but i could not find any method to add image (logo) on to the video. Please suggest me a way to achieve my requirement.

    Thanks,

    P. Sourabh

    Hello,

    You could try:


    gst-launch -e filesrc location=1.png ! pngdec ! imagefreeze ! ffmpegcolorspace ! queue ! videomixer name=mix ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink sync=true videotestsrc ! 'video/x-raw-yuv,width=XX,height=XX' ! mix.

    Best Regards,
