[gst-devel] issue with appsrc and audioresample

[na]

Hello Katcipis,

Thanks for your kind reply.

I changed the caps on the appsrc buffer and caps filter to:

 GstCaps *rescaps;
  rescaps = gst_caps_new_simple("audio/x-raw-int", "rate", G_TYPE_INT,
48000, "channels" ,G_TYPE_INT, (gint)1, "endianness",G_TYPE_INT,(gint)1234,
"width", G_TYPE_INT, (gint)8, "depth", G_TYPE_INT, (gint)8, "signed",
G_TYPE_BOOLEAN, TRUE, NULL);
  g_object_set(capsfilt_res,"caps",rescaps,NULL);

  GstCaps *caps;
  caps = gst_caps_new_simple("audio/x-raw-int", "rate", G_TYPE_INT, 8000,
"channels" ,G_TYPE_INT, (gint)1, "endianness",G_TYPE_INT,(gint)1234,
"width", G_TYPE_INT, (gint)8, "depth", G_TYPE_INT, (gint)8, "signed",
G_TYPE_BOOLEAN, TRUE, NULL);
 gst_buffer_set_caps(app_buffer_src,caps);

However, the result is the same "not negotiated" error.  I have attached the
relevant debug output. If you do have any other ideas, please do let me
know.  Thanks

Best regards,

Nadeem
