<div dir="ltr">You can set the variable GST_DEBUG=<plugin debug name>:N,<plugin #2 debug name>:M,... where N,M are from 0 to 6 or 7 (higher gives more verbose debugging). The variable can be set before running the program (export GST_DEBUG=... on Linux) and can be set dynamically from your app. Check the doc for GST_INFO for more info. A short cut might be to start with GST_DEBG=*:3 to get started and see the names that you are interested in, then enhance the variable for targeted tracing. Some elements can be very verbose. <div class="gmail_extra"> <div class="gmail_quote">On Mon, Oct 12, 2015 at 10:58 AM, symeon.mattes <<a href="mailto:symeon.mattes@gmail.com" target="_blank">symeon.mattes@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, I'm trying to play in iOS a specific file by using something very simple through the filesrc plugin. gst-launch-1.0 filesrc location=song.ogg ! decodebin ! audioconvert ! audioresample ! autoaudiosink However I can't hear from the loudspeaker anything. I have tried different versions such as gst-launch-1.0 filesrc location=song.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! autoaudiosink but with no success. I have tried just to play a simple sinus signal and it worked gst-launch-1.0 audiotestsrc freq=500 ! audioconvert ! audioresample ! autoaudiosink So it seemed either the location of the file is not correct, or there is something wrong with the decoding. Is there any way I could debug it objective-c?
