<p class="MsoNormal">Hi all…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve been playing with the 722 decoder because I’m looking at a telephony app. I create a g722 audio file with the following pipeline:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">gst-launch-1.0 alsasrc device=hw:0,0 ! audio/x-raw, rate=48000, channels=2, width=16, depth=16 ! audioresample ! audioconvert ! audio/x-raw, format=S16LE, channels=1, rate=16000 ! avenc_g722 ! filesink location=./testing.g722<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">my issue come down to decoding this input file. I pared down the decoding to the following pipeline:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">gst-launch-1.0 filesrc location=./testing.g722 ! audio/G722 ! avdec_g722 ! fakesink<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">and still get an error<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal data stream error.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There is some additional information that gstbasesrc.c (3055) streaming stopped, reason error (-5)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Running in higher debug levels I get more information that in gstaudiodecoder.c (2199) indicates that it is an unsupported format. The code seems to fail when checking if we should change from a byte to time format (gstaudiodecoder.c:2184)
that either the context.d_estimate_rate is false, or the format couldn’t be converted from a bytes format to a time format.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Where do I look now for the cause of this error? I would think that a file created with the avenc_g722 would be able to be decoded with the avdec_g722. Am I missing something fundamental?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My version of gstreamer, gstreamer-libav, gstreamer-plugins-base are all 1.14.4<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance,<o:p></o:p></p>
