[gst-devel] using xoverlay

Hi!
Can someone please help me in getting xoverlay to work.
I am able to play video in the default window, but I can't get the xoverlay
window to work.
I came acorss some example codes that suggested passing the videosink
to gst_bus_set_sync_handler instead of pipeline. Even that didn't work.
I'm following the example code below (as given in gstxoverlay ref manual).
I don't have much idea about UI programming.
static GstBusSyncReply
create_window (GstBus * bus, GstMessage * message, GstPipeline * pipeline)
{
// ignore anything but 'prepare-xwindow-id' element messages
if (GST_MESSAGE_TYPE (message) != GST_MESSAGE_ELEMENT)
return GST_BUS_PASS;
if (!gst_structure_has_name (message->structure, "prepare-xwindow-id"))
return GST_BUS_PASS;
win = XCreateSimpleWindow (disp, root, 0, 0, 320, 240, 0, 0, 0);
XSetWindowBackgroundPixmap (disp, win, None);
XMapRaised (disp, win);
XSync (disp, FALSE);
gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (GST_MESSAGE_SRC (message)),
win);
gst_message_unref (message);
return GST_BUS_DROP;
}
...
int
main (int argc, char **argv)
{
...
bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));
gst_bus_set_sync_handler (bus, (GstBusSyncHandler) create_window, pipeline);
...
}
Regards,
Vinod

Hi,
Use the gst_x_overlay_set_xwindow_id() method on your video sink.

Hi,
Is it currently possible to mux simultaneous live video sources (and
one audio) into one container ? In theory, both matroska and mp4
(among others) could do it, but i have really no idea if this is
possible using gstreamer/gst-ffmpeg.
Any hints would be appreciated, like videotestsrc gst-launch pipeline
samples (if this is doable).
Cheers
Florent

Hi!
I am trying to use the gst_x_overlay_set_xwindow_id function as given in the
example code at
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-lib
s/html/gst-plugins-base-libs-gstxoverlay.html#GstXOverlay
But, my code doesn't reach till the point where is actually calls
gst_x_overlay_set_xwindow_id () since the 'prepare-xwindow-id' message is
never received from the bus.
Now, should I be posting 'prepare-xwindow-id' message myself?
Regards,
Vinod

Hi all,
I'm trying to modify gthumb to allow it to read video metadata using
gstreamer. It works, but I seem to be missing something - exiftool can
extract more metadata than gstreamer - like the original recording date.
Is that to be expected?
For instance, an AVI from my Canon PowerShot SD800IS gives the following
in exiftool:
[mjc at flay trunk]$ exiftool -s -G1 MVI_1082.AVI
[ExifTool] ExifToolVersion : 7.00
[File] FileName : MVI_1082.AVI
... snip ...
[RIFF] FrameRate : 30
[RIFF] MaxDataRate : 2024 kB/s
[RIFF] FrameCount : 1103
[RIFF] StreamCount : 2
[RIFF] StreamType : Audio
[RIFF] Codec :
[RIFF] Quality : 10000
[RIFF] SampleSize : 1 byte
[RIFF] Encoding : Microsoft PCM
[RIFF] NumChannels : 1
[RIFF] SampleRate : 11024
[RIFF] AvgBytesPerSec : 11024
[RIFF] BitsPerSample : 8
[RIFF] DateTimeOriginal : 2007:11:23 20:46:30
[RIFF] Software : CanonMVI06
... snip ...
but the gstreamer debug output only shows:
Tags: taglist, video-codec=(string)"Motion\ JPEG";
Tags: taglist, audio-codec=(string)"Uncompressed\ 8-bit\ PCM\ audio";
Tags: taglist, encoder=(string)CanonMVI06;
I would really like to extract the metadata date! (Beware that Exiftool
renames all the tags using its own scheme...)
The source code for my metadata reader is here
http://svn.gnome.org/viewvc/gthumb/trunk/libgthumb/gth-gstreamer-utils.c?view
=markup
Any help would be appreciated!
- Mike

Please file a bug/feature request in bugzilla and make a sample file
available then.

It's because of the fact that this mapping of DTS is from an MPEG-2

Yes, any muxer that can accept 2 streams (1 audio, 1 video) can also
usually do more of each and still be happy.
You just need to request more pads of each type... video_0, video_1, and
send them data.
