GUI Video embedding and stream marking

Hi everybody,

First of all, let me say I'm a completely newbie in the Gstreamer framework. I've just read the Application Development Manual to get a big picture of it. However, I have some doubts regarding what can I really do and how to achieve it.

I want to develop a GUI-based IPTV client application which plays RTSP, UDP and local files in an embedded video frame. Due to additional services, I need to include playlist management and multimedia-synchronized data (such as, let's say, Mercedes-Benz advertisements when watching a specific scene in a James Bond movie). So here are my questions:

- How can I embed Gstreamer's video output into my GUI-based C/C++ application?
- I've read that decodebin has playlist support. How can I give it a try? (any help command?)
- Can I use Gstreamer framework to "mark" media streams and interpret them when receiving in the client side? I.e. having a video file and add metadata information in any specific time such as "get Mercedes-Benz ad" in 00:38:34 time instant. Then, while playing, extract this data and handle it properly in my application.

Maybe my questions can be stupid or simple, I have no experience in video embedding in C/C++ languages and, as each framework may have its own modus operandi, here I am asking for some help.

Thank you all so much for your time,
Javi

Re: GUI Video embedding and stream marking

Any idea about this?

By the way, can PiTiVi help with stream marking like explained below?

Thanks,
Javi

Depend on the gui toolkit you use. Look at gst_x_overlay_set_xwindow_id()
gst-plugins-base/tests/icles has some example for c and gtk+

You'll need to find a video container format that has such capabilities, I don't
know of any. You could mis-use subtitles maybe. I mean have command in the
subtitles which you don't show, but reinterprete and execute.
