<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'>Hello I have a question regarding the use of "gst_element_link_filtered" in my pipeline. My app display harmonics of the sound either from the mic, or from a sound file. If microphone is the source, pipeline looks like this : alsasrc, equalizer, equalizer2, equalizer3, audioconvert1, BP_BRfilter, audioconvert2, spectrum, flacenc, autoaudiosink If an audio file is the source, I use a playbin whose sink is a pipeline like this : audioconvert1, equalizer, equalizer2, equalizer3, audioconvert1, audiochebband, audioconvert2, spectrum, flacenc, autoaudiosink I have seen in the example that spectrum should be linked that way : caps = gst_caps_new_simple ("audio/x-raw", "rate", G_TYPE_INT, AUDIOFREQ, NULL); (or "audio/x-raw-int" in gst-0.10) if (!gst_element_link (src, audioconvert) || !gst_element_link_filtered (audioconvert, spectrum, caps) || !gst_element_link (spectrum, sink)) { fprintf (stderr, "can't link elements\n"); exit (1); } gst_caps_unref (caps); But in my case, "gst_element_link_many" works. 'gst_element_link_filtered" seems unnecessary. Where should I put it to be correct? After each Audioconvert element? In the example of equalizer, a single capsfilter element is created and put between src and equalizer-spectrum-sink. Actually, if I put it or not, it works exactly the same. But since I have a problem of high ratio backgroung noise/sound after porting from gst-0.10 to gst-1.0, I want to see if I can improve something here. Thank you Victor </div></body> </html>
