Is it possible to have two sources in one pipeline?
 
|
Hi,
I want to develop a plugin which uses two video files on input (raw yuv for now) But after few hours of googling and trying different options from gst-launch I cannot figure out how to read input from two files. My plugin has two sinks and one source. I want to use two filesrc as an input and one filesink as an output. Can somebody show the example of usage for gst-launch in that case, please? ------------------------------------------------------------------------------ Come build with us!

You should give the gstreamer manual a good thorough reading.
http://gstreamer.org/data/doc/gstreamer/head/manual/html/chapter-gstreamer.html What you seek to do is the principle reason for which gstreamer was written!

Thank you.
At least you wanted to help. I was asking for gst-launch command specific usage, which I coudn't find in the manuals (plugin writer's and gstreamer manual) and many other pages. I am answering my-self: gst-launch -v encoder name=s264 ! filesink location=./Out filesrc location=./Grasshopper/texture/Grasshopper_Right.yuv ! s264.sink_right filesrc location=./Grasshopper/texture/Grasshopper_Left.yuv ! s264.sink_left encoder has two sinks and to address them I need to name the encoder using 'name'. I was trying to use its name taken from gst-inspect with the index (encoder0.sink_left and encoder0.sink_right) but it wasn't working. After the encoder's name I use sinks names. So the comand line is a little bit different comparing to the simple ones given in the gst-launch manual.

A patch to the man page (gstreamer/tools/gst-launch.1.in) adding an example that demonstrates how to connect to specific pads by name would be much appreciated.

Hi,
I downloaded gstreamer-0.10.25. Should I change the manpage and post diff file here? If yes which file should I change? 2009/11/1 Tim-Philipp Müller <[hidden email]> On Sun, 2009-11-01 at 21:27 +0200, Michael Joachimiak wrote: -- Your Sincerely Michael Joachimiak ------------------------------------------------------------------------------ Come build with us!

Please file a bug in bugzilla (see http://gstreamer.freedesktop.org/bugs/) and attach the diff there, to make sure it doesn't get lost or forgotten about. > If yes which file should I change? tools/gst-launch.1.in Cheers -Tim ------------------------------------------------------------------------------ Come build with us!
