I turned on the log and it prints out : 0:00:00.062400000 [333m 4904 [00m 005429D0 [32;01mINFO [00m [00;01;37;41m GST_ELEMENT_FACTORY gstelementfactory.c:484:gst_element_factory_make: [00m no su ch element factory "filesrc"! I think it's not the problem of path, because the dlls of gstreamer is in PATH and I put it in the command line parameters to make sure: --gst-debug-level=3 --gst-plugin-path="C:/Program Files/FOSS/bin" Any suggestions? </blockquote><div> </div><div>Are you calling gst_init?</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> -- look to the things around you,the immediate world around you, if you are alive,it will mean something to you ——Paul Strand ------------------------------------------------------------------------------ Come build with us!
