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.
