Wrote my first plugin but I keep getting 'gst_segment_clip' error

[danielkun]

Hello,

I wrote a Gstreamer plugin that converts network byte order to little
endian to be able to play LPCM files.

The plugin works fine except for the error message below that appears
once after execution.
Does anyone know what is causing this?

(test_plugin:7275): GStreamer-CRITICAL **: gst_segment_clip: assertion
'segment->format == format' failed

I pasted the code at the end.

Thank you,
Daniel

static GstFlowReturn
gst_endianconvert_chain (GstPad * pad, GstBuffer * buf)
{
  guint32 size;
  guint8 *data;
  Gstendianconvert *filter;

  size = GST_BUFFER_SIZE (buf);
  data = GST_BUFFER_DATA (buf);

  unsigned char c2;
  int i;

  for (i = 0; i < size; i += 2) {
    c2 = data[i + 1];
    data[i + 1] = data[i];
    data[i] = c2;
  }

  filter = GST_ENDIANCONVERT (GST_OBJECT_PARENT (pad));

  return gst_pad_push (filter->srcpad, buf);
}

audioconvert can do that, you don't need to write a new plugin.

There's other code somewhere that you didn't include; the bug is there.
You need to send a proper new segment event before you start sending
data.
