Hi all,<div><br></div><div>I'm attempting to write a simple pipeline to use osxvideosrc to display a captured video using ximagesink,</div><div><br></div><div>My pipeline is</div><div><br></div><div>osxvideosrc ! ffmpegcolorspace ! ximagesink</div> <div><br></div><div>Here's the log I'm getting</div><div><br></div><div><div>Setting pipeline to PAUSED ...</div><div>/GstPipeline:pipeline0/GstOSXVideoSrc:osxvideosrc0.GstPad:src: caps = video/x-raw-yuv, format=(fourcc)UYVY, width=(int)640, height=(int)480, framerate=(fraction)30/1, pixel-aspect-ratio=(fraction)1/1</div> <div>Pipeline is live and does not need PREROLL ...</div><div>Setting pipeline to PLAYING ...</div><div>New clock: GstSystemClock</div><div>ERROR: from element /GstPipeline:pipeline0/GstOSXVideoSrc:osxvideosrc0: Internal data flow error.</div> <div>Additional debug info:</div><div>gstbasesrc.c(2334): gst_base_src_loop (): /GstPipeline:pipeline0/GstOSXVideoSrc:osxvideosrc0:</div><div>streaming task paused, reason not-negotiated (-4)</div><div>Execution ended after 184031000 ns.</div> <div>Setting pipeline to PAUSED ...</div><div>Setting pipeline to READY ...</div><div>/GstPipeline:pipeline0/GstOSXVideoSrc:osxvideosrc0.GstPad:src: caps = NULL</div><div>Setting pipeline to NULL ...</div><div>Freeing pipeline ...</div> <div><br></div><div>Clearly the caps negotiation aren't matching. However, I tried using different caps after the ffmpegcolorspace element but still not getting a successful negotiation. </div><div><br></div><div>Has anyone tried something similar? Can someone show me a working pipeline? Much appreciated.</div> <div><br></div><div>William</div><br>-- <br><br>William Lee @ Breeze Capsule<br>Email: william at <a href="http://breezecapsule.com">breezecapsule.com</a><br>Mobile: +44 7984 368 182<br> </div>
