Decoding Axis G726-24 audio

[mingqian Han]

Hi,    I am facing an issue when decoding g.726 stream from an Axis encoder. The audio is mono at 8K sample rate, g.726 24kbps encoded, rtsp/rtp streaming.    The test pipeline :     gst-launch-1.0.exe -v rtspsrc location=rtsp://10.51.252.189/axis-media/media.amp ! rtpg726depay ! avdec_g726 ! audioconvert ! audioresample ! volume volume=0.1 ! autoaudiosink
     The pipeline works but all is noise.
     If I set Axis audio codec to be g.726, 32kbps, the pipeline works and music can be heard with some noise.
     In both cases, the Axis IE plugin (AMC) works well, no noise at all.
     I am using gstreamer-1.0.2, good-1.0.2, gst-libav-1.0.2, with modifications in gst_ffmpeg_caps_with_codec_id, (bits_per_coded_sample), to make the pipeline work.
     Could anyone help me?     Thanks!
