question about fakesrc

[acolubri]

In all the examples I've found about pushing user-defined buffers
through fakesrc, for example:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-data-spoof.html
the bpp and depth are always both set to 16. Is this a limitation of
fakesrc? I have tried sending 32
bits buffers with rgba data, but without success.

Does anyone have more examples/code samples involving fakesrc?

Many thanks.
Andres

I guess you need to include a caps filter in between your src and
sink.  Since fakesrc and fakesink could handle any caps, I used audio
ones.

gst-launch fakesrc sizetype=2 num-buffers=5 ! audio/x-raw-int,
width=32, depth= 32 ! fakesink

check on your caps for your actual sink and just change them to
something more accurate.

I hope this helps.

Daniel.

Thanks for the answer!

However, I did some testings setting the caps to the desired value
(bpp=32, depth=24 in my case), but my application hangs... I guess I'll
keep playing around with this.

I've also read that there is a new element called GstAppSrc that makes
this type of operations (injecting buffers into the pipeline) much
easier. Do you have any code example with this element?
