[vlc-devel] udp network timeout

[Dermot McGahon]

Hello,

I'm trying to implement a timeout for udp streams. If data hasn't
been received for a couple of seconds, tear down instead of
displaying the last received frame.

The var_Set( p_this, "key-pressed", p_val ) below isn't tearing
down the stream.

Is there a another approach or how could this one be made to work?
