<DIV>I am new to gstreamer.My board filesystem(angstrom-distribution) is supplied by board provider. there is not libgstvideo4linux2.so under /usr/lib/gstreamer-0.10/, I copied one from other build filesystem.</DIV>
<DIV>when I run</DIV>
<DIV><A href="mailto:root@taodemo" target="_blank" _listener="656">root@taodemo</A>:~# gst-launch -e v4l2src location=file.mov<BR>ERROR: pipeline could not be constructed: no element "v4l2src".<BR><A href="mailto:root@taodemo" target="_blank" _listener="657">root@taodemo</A>:~# gst-inspect v4l2src<BR>No such element or plugin 'v4l2src'</DIV>
<DIV> </DIV>
<DIV>my question is:</DIV>
<DIV>1: If I must do some configuration before to use v4l2src?</DIV>
<DIV>2. How can I build gstream and it's plugin on my own?</DIV>
<DIV>3. I am not sure what must i do to capture video data from RCA composite and compress to mp4:</DIV>
<DIV> I am using a board similar to DM37x Evaluation Board(dm3730 on it)</DIV>
<DIV> If I understand right, the video data is from RCA Composite to tvp5146, and to ISP module in cpu</DIV>
<DIV> My task is read data from RCA Composite, and encode it to mp4. How can i do it?</DIV></DIV></div><br><br><span title="neteasefooter"><span id="netease_mail_footer"></span></span>
