Hi Sean,<div><br></div><div>Yes, what I was trying is to resample the decoded mp3 data to the fixed (22KHZ S16LE) formate, </div><div><br></div><div>no matter what is the input rate using <span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; color: rgb(80, 0, 80); ">a C application.</span></div>
<div><br></div><div>Thanks for your response.</div><div><br></div><div>Here is the piece of the code for the same but it does not work with audioresample with the caps filter '<font class="Apple-style-span" color="#FF0000">resmux</font>'.

<p>Hi,</p>
<p>I don't entirely understand your question. Are you trying to convert a pipeline into an equivalent C application? Doing so is just based on understanding of C and the gstreamer C API... it is certainly possible, insofar as your pipeline is valid.</p>
<p>That said, look at gst_parse_* functions for a way to enter a pipeline spec in the gst-launch syntax and get either a GstBin or a GstPipeline out of it.</p>
