Hello,<br>
<br>
I am trying to read raw video data from a file and then encode it using theora encoder. I would like to use standard test videos such as these:<br>
<a href="http://media.xiph.org/video/derf/" target="_blank">http://media.xiph.org/video/derf/</a> (uncompressed YUV4MPEG, says it is the format accepted by the Theora encoder tools)<br>
<a href="http://trace.eas.asu.edu/yuv/" target="_blank">http://trace.eas.asu.edu/yuv/</a><br>
<br>
I have tried with a pipeline like this: filesrc | ffmpegcolorspace | theoraenc | oggmux | filesink and the videos from the links above but I am getting the Error: not negotiated.<br>
<br></blockquote><div><br>Try:<br>filesrc ! decodebin | ffmpegcolorspace | theoraenc | oggmux | filesink<br><br>decodebin is an element to "Autoplug and decode to raw media"<br><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;">
Everything works if I substitute the file source with the test source videotestsrc or a webcam v4l2src but this does not allow me to use standard test videos.<br>
Is something missing in my pipeline or am I using the wrong format?<br>
Any suggestions will be appreciated.<br>
<br>
Thank you in advance,<br>
Katarina<br>
