    <p>For my project, I am trying to use a gumstix overo, with gstreamer and the TI plugin for making use of the DSP in order to stream video via RTP. I found these two tutorials and have even been able to follow them successfully:</p> <p><a href="http://jumpnowtek.com/index.php?option=com_content&amp;view=article&amp;id=81:gumstix-dsp-gstreamer&amp;catid=35:gumstix&amp;Itemid=67" rel="nofollow">http://jumpnowtek.com/index.php?option=com_content&amp;view=article&amp;id=81:gumstix-dsp-gstreamer&amp;catid=35:gumstix&amp;Itemid=67</a></p> <p>^^In this one I am able to compile an embedded linux os, with gstreamer and the GstTIPlugIn Element. after doing so, I am able to stream the videotestsource to a remote PC successfully.</p> <p>However that tutorial is meant for a caspa video cam, I am using the Logitech Pro C920 used in this tutorial:</p> <p><a href="http://www.oz9aec.net/index.php/gstreamer/473-using-the-logitech-c920-webcam-with-gstreamer" rel="nofollow">http://www.oz9aec.net/index.php/gstreamer/473-using-the-logitech-c920-webcam-with-gstreamer</a></p> <p>^^In this one we make use of a C920 camera in H264 mode. since the V4l2 drivers do not support this, we use a c script to capture from the camera frame by frame and stream it to standard out. From here we tell Gstreamer to capture from a file source, in this case standard in (/dev/fd/0). Again I am able to complete this successfully and stream from the C920 camera, however without using the TIplugin for making use of DSP.</p> <p>Now on to the problem:</p> <h1>./capture -c 10000 -o | gst-launch -v -e filesrc location=/dev/fd/0 ! h264parse ! rtph264pay ! udpsink host=192.168.1.100 port=4000</h1> <p>^^This command will run the capture program, and gstreamer will grab and stream the video using the h264parse pipeline to encode (I believe?)</p> <p>when I replace h264parse with the TIplugin from the first tutorial like this:</p> <p>./capture -c 10000 -o | gst-launch -v -e filesrc location=/proc/self/fd/0 ! TIVidenc1 codecName=h264enc engineName=codecServer ! rtph264pay ! udpsink host=192.168.1.100 port=4000</p> <p>I get this error:</p> <p>Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstTIVidenc1:tividenc10: failed to create video encoder: h264enc</p> <p>Additional debug info: gsttividenc1.c(1584): gst_tividenc1_codec_start (): /GstPipeline:pipeline0/GstTIVidenc1:tividenc10 ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ...</p> <p>I also tried keeping both elements in and then the error says it cannot link h264parse0 to tividenc10</p> <p>Has anyone had any experience with the GstTIPlugin and know what I'm doing wrong? thanks</p>
