For example, I would have (if I translate to command line):</DIV> <DIV>gst-launch filesrc location=myfile.avi ! decodebin ! ffmpegcolorspace ! directdrawsink and at some time I want to switch to videotestsrc ! ffmpegcolorspace ! directdrawsink (and vice-versa)</DIV> <DIV>That is, I either get my frames from the (filesrc+decodebin) or the (videotestsrc) elements.</DIV> <DIV>Is there a way to keep 2 such 'subpipelines' created, while only one is currently linked to the sink? </DIV> <DIV>- If I create and add all the elements to the main pipeline but only link one branch, I get ofcourse a 'nonlinked' error for the other branch. </DIV> <DIV>- If I create all, but only add the branch I use (with gst_bin_add_many), then remove the branch (with gst_bin_remove_many) and add the new one it works. But if I want to revert again, then the elements that got removed in the first place cannot be added again.</DIV> <DIV>Is there a way to keep a bunch of elements such that I can add/remove them from the pipeline anytime I want (without having to recreate them) ?</DIV> <DIV> </DIV> <DIV>Best Regards,</DIV> <DIV>Al</DIV></div><br> </body></html>
