Hello,

You can see the section 7.3.1.6.3 of the Linux Users guide. There you can find an example of how to perform multiple videos overlay.

Hi Diego Adrian Cuevas,

       I have already tried this command

gst-launch-1.0 playbin uri=file://$FILE1

video-sink="overlaysink overlay-width=512 overlay-height=384"

playbin uri=file://$FILE2 flags=0x41

video-sink="overlaysink overlay-left=512 overlay-width=512 overlay-height=384" 

so i got this error

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstGioSrc:source: Could not open resource for reading.
Additional debug info:
../../../git/gst/gio/gstgiosrc.c(335): gst_gio_src_get_stream (): /GstPlayBin:playbin0/GstURIDecodeBin:uridecodebin0/GstGioSrc:source:
Could not open location file://FILE1 for reading: Operation not supported
Setting pipeline to NULL ...

how to give the uri path for a video in terminal and can we give our video names or else filename should be FILE1.

In which file can we store the videos like(mount,dev).

Hello, 

To give a path to the playbin video source, you can use it as below:

$ gst-launch-1.0 playbin uri=file:///<the path where is located your video>

For example:

$ gst-launch-1.0 playbin uri=file:///home/root/video_test.mp4

Hope this can help you.

Best regards,

Diego.
