Gstreamer supports remote acquisition and UDP transmission of cameras. It is locally displayed and saved as the AVI file sender.

After two weeks of efforts, gstreamer has finally completed remote camera acquisition, UDP transmission, local display and storage as AVI files, and now I will share with you the C language program. Thank you for your comments.

This program has the problem of short recording time but long playback length saved as a file. I hope you can learn how to solve it. Thank you !!!!
