[gst-devel] GStreamer-CRITICAL **: gst_bin_add: assertion `GST_IS_ELEMENT (element)' failed

[Guilherme]

    Just for reference, I know that I have to specify a buffer size in 
case of non-live audio streamer, but my audio comes from a live src 
(alsasrc).
   
    For video the size would be calculated as:

          size = width * height * bpp;
          GST_BUFFER_SIZE (buffer) = size
          GST_BUFFER_MALLOCDATA (buffer) = g_malloc(size);        

    And for a live src???

Tks!
