<html> <head> <style> .hmmessage P { margin:0px; padding:0px } body.hmmessage { font-size: 10pt; font-family:Verdana } </style> </head> <body class='hmmessage'> Hi Sudarshan, by the way, the receiver continues to run even when the sender is stopped. Is there a way that i can tell to udpsrc to stop receiving if there is no data on the port? Actually, when i see the file there is no empty part. I mean it contains only the data sent from the sender side and not an empty frame as I had expected. Since I want to use in a program later, i want to stop the recorder when the sender finishes sending the video. I hope there could be a way to do that. Thank you.
