Hi Luis,


Thanks for the review.

I am using a simple pipeline to test the same

gst-launch-1.0 filesrc location=../media/icon.png ! pngdec ! videoconvert !
ximagesink


And the value 12 is because of below

    if (!gst_byte_reader_get_uint32_be (&reader, &length))
      goto need_more_data;
    if (!gst_byte_reader_get_uint32_le (&reader, &code))
      goto need_more_data;
    if (!gst_byte_reader_skip (&reader, length + 4))
      goto need_more_data;

4 for uint32_be, 4 for uint32_le and length + 4 for skip

so total of length + 12
