"reason not-negotiated" with eglglessink (gst-plugins-bad 1.2.3/09 Feb 2014)

[Michael Tyson]

Hi guys,

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.

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 vontaene.de which was working reasonably well with the following pipelines, run on two different Raspberry Pis:

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

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

(The new build new also works with TX using omxh264enc, happily, with "gst-launch-1.0 v4l2src ! 'video/x-raw, width=1280, height=720, framerate=30/1' ! queue ! videoconvert ! omxh264enc target-bitrate=1048576 control-rate=1 ! rtph264pay !  udpsink host=192.168.1.134 port=9000”)

With the new build, however, on the RX side I’m receiving the error "ERROR: from element /GstPipeline:pipeline0/GstOMXH264Dec-omxh264dec:omxh264dec-omxh264dec0: Internal data stream error. / stream stopped, reason not-negotiated”. If I use a different sink (fakesink or fbdevsink), it appears to work - although fbdevsink runs incredibly poorly.

Here’s the full verbose output, with the caps info: 

http://f.cl.ly/items/2z1R1i1a161m2Q0Q453L/Setting%20pipeline%20to%20PAUSED%20Pip.txt

And some PNGs of the dot graphs derived from using GST_DEBUG_DUMP_DOT_DIR: 

READY_PAUSED: http://cl.ly/image/1i2D0P2o3w2t
ERROR: http://cl.ly/image/250s2z2H0J3p

Can anyone suggest where I should be looking next? 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.

Many thanks in advance,

Best,
Michael
