hi all:
I wrote my gst app which used realvideodec
element like this( ignored some non-significant code):
main()
{
........
pthread_creat(&my_thread, null,
create_pipe_func, null);
while(1)
{
c =
getchar();
if(c = 'b')
{
sleep(10);
}
}
}
create_pipe_func()
{
loop = g_main_loop_new(null,
false);
pipeline = _create_pipeline();//make
all element and link them, set pad-added callback for delayed link to
realvideodec sink pad
gst_element_set_state(pipeline,
GST_STATE_PLAYING);
g_mainn_loop_run(loop);
}
my pipeline is like this:
filesrc --> rmdemux -->
realvideodec --> fakesink
my problem is:
I use the app to play rv4 file, and stream thread blocked on
close_library().
gst log like this(sorry, I can not copy and paste for some
reason, so i type some significant logs):
------------------------------------------------------------------------------------------------
gstelement.c:2496:gst_element_set_state_func:<realvideodec0> final:
set state from NULL to READY
gstrealvideodec.c:456:open_library:<realvideodec0>
Attempting to open shared library for real video version 2
....
gstrealvideodec.c:557:close_library:<realvideodec0>
closing library module
gstrealvideodec.c:456:open_library:<realvideodec0>
Attempting to open shared library for real video version 3
....
gstrealvideodec.c:557:close_library:<realvideodec0>
closing library module
------------------------------------------------------------------------------------------------
no more things logged. I added some print to glib source code
and found that dlclose() blocked.
if i input 'b' now , stream tread unblocked
and went on correctly.
If my code like :
main()
{
........
create_pipe_func();
}
create_pipe_func()
{
loop = g_main_loop_new(null,
false);
pipeline = _create_pipeline();//make
all element and link them, set pad-added callback for delayed link to
realvideodec sink pad
gst_element_set_state(pipeline,
GST_STATE_PLAYING);
g_mainn_loop_run(loop);
}
every thing is ok.
why?
