When I play a rtsp stream on vlc, when try to press "back" button, I will get the error as below:

Seems like a bug.

Seems like a bug.

Do you how to report the bug? : )

I think I can give more details about it. When we try to stop the play, then we will have to wait almost 1 minutes until it really stop. In the process, I only see

It doesn't happen when I play avi files.

I have created ticket 7269.

In file live555.cpp:
static void Close( vlc_object_t *p_this )
{
demux_t *p_demux = (demux_t*)p_this;
demux_sys_t *p_sys = p_demux->p_sys;

msg_Dbg( p_demux, "kc test: come to live555 Close" );

if( p_sys->p_timeout )
{
//kc test
msg_Dbg( p_demux, "kc test: come to vlc_cancel" );
vlc_cancel( p_sys->p_timeout->handle );
msg_Dbg( p_demux, "kc test: come to vlc_join" );
vlc_join( p_sys->p_timeout->handle, NULL);
//kc test
free( p_sys->p_timeout );
}
msg_Dbg( p_demux, "kc test: come to if( p_sys->rtsp && p_sys->ms )" );

if( p_sys->rtsp && p_sys->ms ) p_sys->rtsp->sendTeardownCommand( *p_sys->ms, NULL );

I find it spends a lot of time on running vlc_join( p_sys->p_timeout->handle, NULL);
it seems the thread can't be killed. But after about 1 minutes, it will be killed.

It means the other thread is not done...
