I got the valid pipeline now. Following is the pipeline which serves my purpose. gst-launch -v \ videomixer name=mix sink_1::xpos=500 sink_1::ypos=760 sink_1::alpha=0.9 sink_1::zorder=3 sink_2::xpos=400 sink_2::ypos=100 sink_2::zorder=2 background=3 \ ! xvimagesink sync=true \ filesrc location=Sample.png \ ! pngdec ! queue ! ffmpegcolorspace \ ! imagefreeze ! mix. \ filesrc location=Sample.mp4 \ ! qtdemux ! queue \ ! legacyh264parse ! queue ! ffdec_h264 \ ! ffmpegcolorspace \ ! mix. Let me know if anyone sees any improvement in this.

As I wanted to see my image file should freeze on screen while video is getting played back with its normal speed. With this pipe line I'm not able to see my image though pipeline does not give any error. Can any one has suggestion to try?

I'm using below pipeline. If I run either image or video individual with videomixer its running fine. But when I combine this, same gives segmentation fault (Corrupt stack). gst-launch -v \ videomixer name=mix \ ! xvimagesink sync=false \ filesrc location=Sample.mp4 \ ! qtdemux \ ! legacyh264parse ! ffdec_h264 \ ! mix. \ filesrc location=Sample.png \ ! pngdec ! ffmpegcolorspace \ ! imagefreeze ! mix.
