Description Nikolin Dmitriy 2015-09-15 08:01:55 UTC
sender raspberry pipeline: raspivid -t 0 -w 960 -h 540 -fps 30 -b 1500000 -pf baseline -o - | gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay config-interval=2 pt=96 mtu=1380 ! udpsink host= port=6000

receiver iphone pipeline : udpsrc port=6000 ! application/x-rtp, payload=96 ! rtph264depay ! h264parse ! vtdec ! glimagesink

With vtdec. No more broken colors or latency but have new bug. Avery 1-2 maybe 3 seconds get 1ms freeze. Test on iPhone 4s, iPhone 5 and iPad Retina. changes of frame size or bitrate does not help. 40-50% CPU usage. 
If use decodebin - 90-100% CPU usage but no freezes. 


GST_LEVEL_DEBUG iphone can't start stream. black screen and infinity log.

Hi Nikolin.

  Does this issue still happen with current gstreamer ? There have been quite a few fixes over the past 3 years.
