Thank you so much Vrinda. I was following the same steps that you gave. And I was getting the warning
stowrs: Unrecognized option: --bearer
Try `stowrs --help' for more information.
I was using dcm4che-5.16.3. So I upgraded to dcm4che-5.21.0 and I was able to send the video file successfully. Once again thank you for your time.
