osxvideosink: how to get the window id?
 
|
Hi,
as i understand the latest osxvideosink now supports the xoverlay interface and i can set the output window via gst_x_overlay_set_xwindow_id(). My app (based on wxwidgets) is running fine on windows and linux, but on osx i dont know how to get the window id to redirect the video to my own window. Is there any example how to do this on osx? Thank you, Thomas |

The message needs to be handled synchronously by the application.

Hm, atm i do the following
Windows: HWND window = (HWND)MainFrame->EmbeddedVideoWindow->GetHandle(); Linux: Window window = GDK_WINDOW_XWINDOW(GTK_PIZZA(MainFrame->EmbeddedVideoWindow->m_wxwindow)->bin_window); Is there no similar simple thing under OSX for wxMac? Thomas |

Does this mean that it won't work for osxvideosink now? Will I have to construct the pipeline manually and link the pads, etc Really? Ouch. :( Thanks Antoine > thanks in advance. > regards. > _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hah, I also get a bus error, I assumed it was because osxvideosink needed a window or something. Anyone?

What is this "nsview" fix? I have a gtk.DrawingArea as self.movie_window in my app to embed the videos from gstreamer (i use playbin...) here's my on_sync_message function (with pygtk 2.24) def on_sync_message(self, bus, message): if message.structure is None: return win_id = None message_name = message.structure.get_name() if message_name == "prepare-xwindow-id": if sys.platform == "win32": win_id = self.movie_window.window.handle elif sys.platform == "darwin": print self.window.window.nsview win_id = self.movie_window.window.nsview else: win_id = self.movie_window.window.xid gtk.gdk.threads_enter() self.sink.set_xwindow_id(win_id) gtk.gdk.threads_leave() the nsview now return the window id correctly BUT i can t play any videos... it was working when i builded gtk, gstreamer.... with x11 but now i rebuilded it all with +no_x11 +quartz and now i just have bus_error osx crash report : http://pylonshq.com/pasties/a0d90ebdc8ae993120b6b50dcb075a24 if someone have an idear or know where i can report it... thanks > >> don t know for wxwidget...But now i have a bus error when >> trying to play a video with osxvideosink... i posted 1 week ago on this >> list but my post is still pending ... > Hah, I also get a bus error, I assumed it was because osxvideosink > needed a window or something. > > Anyone? > > Thanks > Antoine > > >> >> good luck... >> >> thanks >> >> Antoine Martin a écrit : >>> On 06/23/2010 06:01 PM, Farkas Levente wrote: >>> >>>> On 06/23/2010 12:27 PM, Philippe Normand wrote: >>>> >>>>> On Sun, 2010-06-13 at 07:30 -0700, Thomas Loewe wrote: >>>>> >>>>>> Hi, >>>>>> >>>>>> as i understand the latest osxvideosink now supports the xoverlay >>>>>> interface >>>>>> and i can set the output window via gst_x_overlay_set_xwindow_id(). >>>>>> >>>>>> My app (based on wxwidgets) is running fine on windows and linux, >>>>>> but on osx >>>>>> i dont know how to get the window id to redirect the video to my >>>>>> own window. >>>>>> >>>>>> Is there any example how to do this on osx? >>>>>> >>>>>> Thank you, >>>>>> Thomas >>>>>> >>>>> The osxvideosink sends a pointer to a NSView to the application via a >>>>> message containing a have-ns-view structure, small snippet: >>>>> >>>>> if (gst_structure_has_name(message->structure, "have-ns-view")) { >>>>> videoWindow =(NSView*) >>>>> g_value_get_pointer(gst_structure_get_value(message->structure, >>>>> "nsview")); >>>>> >>>>> Then you can map the NSView to a NSWindow and show it.
