Hi Johan,<br>
<br>
In GStreamer 0.10.x format type should be GST_TYPE_FOURCC, not<br>
G_TYPE_STRING and the value just "UYVY".<br>
<br>
I guess you're reading documentation for GStreamer 1.0 where the format<br>
type is indeed G_TYPE_STRING and the value should be "UYVY". The FOURCC<br>
type has been refactored in GStreamer 1.0.<br>
<br>
BTW, my personal advise is to use gst_parse_launch() wherever you can<br>
which will save you time and effort as it allows you to specify<br>
pipepline description as you do on the command line. IMHO this is<br>
simpler and less error prone. You can still refer to individual elements<br>
by their name property. Construct the pipeline on a bit-by-bit basis<br>
only when it's absolutely necessary.<br>
<br>
