Hello Damien,
first of all sorry about having caused some uneccessary work by not respecting
the coding
convetions, I think I got confused between varios projects.. Yes, you are
right, Xlib calls are
not threadsafe and thus have to be protected by XLockDisplay and XUnlockdisplay
in a MT
application. I did not notice that until about a week ago because all
applications that I was
looking at to get some XVideo knowledge are singlethreaded - and decent
documentation about XVideo
is very sparse... However I have located a possible issue: in case of using
Xlib calls in an MT
app, a XInitThreads() has to be executed before the first Xlib call, i.e. in
this case before
gtk_init(). In case the respective Xlib does not support MT XInitThreads return
0 and in this case
I simply do an exit(1), however to be 100% correct this should just be used as
an indication to
directly fall back to gdk output - however I have no idea how likely that is
and how to pass on
this information to videooutput_ekiga... I have attached a patch containing the
difference between
the last patch I sent you (please check that you have been using xvideo3.patch,
in case you are
based on one of the earlier patch I can make you another diff). In this patch I
tried to filter
out the changes in the corresponding files due to the update of the original
ekiga SVN. This patch
fixes the following issues:
- Xlib calls should be threadsafe now
- fixed HAS_XV warning
- fixed compiler warings
- FS menu entry now depends on SDL, XV and XV fallback
- 0x0 frame size fix if remote image was not available
- solves issue of flickering PiP
- PiP in window mode similar to PiP in encrusted mode
- solves moving windows when going to FS and returning
- additional XSync possibly against a third black XV window in the background
Concerning the rework on GDK, please tell me if I can be of any help - in my
opinion the following
functions should be in videooutput_gdk.cpp instead of main.cpp (perhaps we can
kick out all the
ifdef HAS_SDL and leave only the if defined HAS_XV || defined HAS_SDL):
void gm_main_window_update_video (GtkWidget *main_window,...
gboolean gm_mw_init_fullscreen_video_window (gpointer data)
gboolean gm_mw_poll_fullscreen_video_window (GtkWidget *main_window)
gboolean gm_mw_destroy_fullscreen_video_window (gpointer data)
In case with the reworked xv support you are still getting crashes I would like
to have a look at
a backtrace if possible...
Thanks in advance,
Matthias
