It seems that we have a format problem between AMR-NB output (GST_FORMAT_BYTES) and ALSA input (GST_FORMAT_TIME). GStreamer returns following warning : (<unknown>:24318): GStreamer-CRITICAL **: gst_segment_clip: assertion `segment->format == format' failed <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> Decode seems correct when calling gst_pad_push function, but ALSA never receives data. Thanks a lot for your help </body> </html>
