image overlay on video stream in playbin2 from 0.10

[KAO George -EXT]

I am using the windows release 0.10 from SDK. I have successfully prototyped it using decodebin2, videomixer, and imagefreeze using gst-launch but I would like to have the functionality of image overlay on the video stream within the pipeline handled with playbin2. Would that be possible?

Sure, you could set a bin to "video-sink" properpy and compose what you
want on top of the video output.

I am able to build a pipeline with playbin using textoverlay but not able to
display a logo on top of the video. My pipeline is "gst-launch-1.0.exe
playbin uri=rtsp://161.85.89.220:8554/test video-sink='textoverlay
font-desc=Sans,36 text=Hello ! autovideosink' "
How do I modify it to overlay a logo on the image ?

Thanks,
Shyam

There is also a "video-filter" property on playbin, which I would
recommend for this use case.

Is the overlay a static image in png or jpeg format (or tiff/bmp or
somesuch)? In that case, gdkpixbufoverlay should do the trick (location
property).

Cheers

There is multiple options, but I'll suggest using gdkpixbufoverlay.

Thanks,

I am unable to use gdkpixbufoverlay.
The below command gives warning saying "erroneous pipeline: no element
"gdkpixbufoverlay" "

 gst-launch-1.0.exe playbin uri=rtsp://161.85.89.220:8554/test
video-sink='textoverlay font-desc=Sans,36 text=Hello ! autovideosink'
!gdkpixbufoverlay location=c:/users/ing03879/desktop/info.png

Also, the below command doesnt give any error. But the video doesnt have the
logo overlayed..

gst-launch-1.0.exe playbin uri=rtsp://161.85.89.220:8554/test
video-sink='textoverlay font-desc=Sans,36 text=Hello ! autovideosink
!gdkpixbufoverlay location=c:/users/ing03879/desktop/info.png'

Thanks,
Shyam

Sure:

gst-launch-1.0 playbin uri=rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov \
                       video-filter="gdkpixbufoverlay location=my_logo.png"

Follow this link [0] for more configuration of the overlay. It can
position the overlay, and also scale it.
