[gst-devel] Contructing gstreamer pipeline with smpte and xvimagesink

[Edward Hervey]

Hi,

   The problem is smpte is creating output buffers which are too big.

   Thanks for reporting the issue, this is now fixed in gst-plugins-good cvs :

        * gst/smpte/gstsmpte.c: (gst_smpte_collected):
        Allocate buffers of the right size.
        The proper size of a I420 buffer in bytes is:

            width * height * 3
            ------------------
                    2
