Is there any plugin named "videoparser " ? Or is it a plugin written by you ? There is h264parse also which can be used here. <div> <div class="gmail_quote">On Sun, May 1, 2011 at 1:05 AM, Faisal Mehmood <<a href="mailto:faysal.99@gmail.com">faysal.99@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi experts, As I am new to gstreamer, so some very basic level quireies are here. At the moment I want to make a small application whose input is a YUV I420 stream from a local disk. Application then encode it to h.264 and then write back to local file system. For this I have installed gst-plugins-ugly for x264enc which is successfully installed in my system, my application can make all the elements successfully. But I am receiving the following error while I launch my application. /***/ pipeline: filesrc location=akiyo_qcif.yuv blocksize=38016 ! videoparser width=176 height=144 framerate=(fraction)15/1 format=(fourcc)I420 ! x264enc ! filesink location=test.264 Now playing: akiyo_qcif.yuv Running... Error: Internal data flow error. Returned, stopping playback Deleting pipeline /***/ please find the attached file for code reference.
