Client cann't send keep-alive if using TLS.

[Rodrigo Pimenta Carvalho]

Hi.

When my rtsp server (test-video.c example) is not with TLS, everything is ok
and the client can receive a video stream for a long time without problems.

On the other hand, if the same rtsp server is with TLS, the same client
receives the video stream, but only for 1 minute. After 60 seconds it rises
an error and the video is interrupted.

The command for the client is:
gst-launch-1.0 -v -m --gst-debug-level=3 rtspsrc
location="rtsps://user:password@192.168.0.80:8554/test"
tls-validation-flags=generic-error  ! rtph264depay ! h264parse ! imxvpudec !
videoconvert ! autovideosink

End the erro log is:

Setting pipeline to READY ...

What should I do in this case??
What is wrong with the client (or maybe with the server)?

P.S.: the server was built with gstreamer 1.8.1. But the client is being
executed in a machine with gstreamer 1.4.1.



Any hint will be very hepful!

Best regards.
