Image Overlay

Hi,

I have to write a C/C++ application that streams videos to an icecast server.
For this application we need to add an image in one corner of the video like
flumotion does. I found gstreamer have text and time overlay but no image
overlay. Does someone know how to do that ?

Regards.

Re: Image Overlay

By hardware imposing, like Sensoray Model 516/616/2246 does, would be a good
way to do the image overlay.

Phil Pellouchoud

can't record audio fast enough...

Hi,

I am trying to write a source plugin on windows and I've gotten to the
point where I can "inspect" the plugin and
Add it to a pipe using:
gst-launch-0.10.exe hdr location=test.hdr ! autoaudiosink

Initially, it just sits there and spews out random data; which sounds
like white noise. After a short burst of noise later, it comes up with
this message.

WARNING: from element /pipeline0/hdrsrc0: Can't record audio fast enough
gst_hdr_read() - length 1764
Additional debug info:
E:\devel-release\src_releases\gst-plugins-base\gst-libs\gst\audio\gstbas
eaudiosrc.c(668): (function) (): /pipeline0/hdrs
rc0:
dropped 7497 samples

I'm trying to figure out what that means in the context of what I'm
trying to do.

I am not quite sure what the gstaudiosrc_class->delay is for -- I am the
"source" of the data (from a file), so I can go pretty fast. I always
return zero for that.

Anyway, any ideas on why I'm getting this? I'm afraid I'm missing some
fundamental concept

-phil

You could use Boxtream (http://boxtream.unice.fr) which does just this,
and more.

The last time I checked though, there was no way to remove an
image overlay during encoding, because of a limitation in GStreamer
(was last year, so maybe the problem is fixed)

There is videomixer. You would need something like

gst-launch \
filesrc location=<videofile> ! decodebin2 ! videomixer name=m ! xvimagesink \
filesrc location=image.jpeg ! jpegdec ! freeze ! m.

In reply to this post by Edgard Lima

Hi,

I had a look to gstgdkpixbufoverlay and I made some modifications. What is the
good way to publish the modifications ?

On bugzilla I read that this element should be in gst-plugins-bad instead of
-good. Should I prepare diff files and sources from CVS or from the last stable
release ?
