</div>Use videoparse for raw files.<br>
<br></blockquote><div><br>Great tip, I wish I'd known about that element before. Here's the working launch line:<br><br> gst-launch -v filesrc location=akiyo_qcif.yuv ! videoparse width=176 height=144 ! xvimagesink<br>
<br>You can also set the format property as needed (for other colorspaces).<br>-Tristan<br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
