<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">Hi guys,<div><br></div><div>I’m running into some difficulties with the eglglessink sink from gst-plugins-bad 1.2.3, and having a tough time understanding the error/debug messages I’m seeing, and thus figuring out the best way forward. I’d love some guidance, if anyone’s got some experience deciphering this output.</div><div><br></div><div>I’ve built debs for GStreamer 1.2.3 for Raspbian (from the experimental/sid Debian branches), in an attempt to have everything up to date and working with Python. I was using the (Python-less) 1.0 packages from <a href="http://vontaene.de">vontaene.de</a> which was working reasonably well with the following pipelines, run on two different Raspberry Pis:</div><div><br></div><div>TX: raspivid -n -w 1280 -h 720 -b 1000000 -fps 30 -vf -hf -t 0 -pf high -o - | gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay ! udpsink host=192.168.1.134 port=9000<br><br>RX: gst-launch-1.0 -v udpsrc port=9000 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! h264parse ! omxh264dec caps='video/x-raw, width=1280, height=720, framerate=30/1' ! queue max-size-time=100 ! eglglessink sync=false<br><br></div><div>(The new build new also works with TX using omxh264enc, happily, with "gst-launch-1.0 v4l2src !

I did notice the caps info at the right side of that graph image only seemed to mention RGBA, BGRA and ARGB image formats, and not the I420 format mentioned in the debug output, but I’ve no idea what to do with that info, or if it’s actually relevant.</div><div style="margin: 0px;"><br></div><div style="margin: 0px;">Many thanks in advance,</div><div style="margin: 0px;"><br></div><div style="margin: 0px;">Best,</div><div style="margin: 0px;">Michael</div><div style="margin: 0px; font-size: 10px; font-family: Monaco;"><span style="font-family: Helvetica; font-size: 12px;"><br></span></div></body></html>
