Hi all,

I upgraded gstreamer from 1.2 to 1.4 and the following pipeline does not
stream cause all frames are dropped. Based on the bus messages the issue is
related with qos.

gst-launch-1.0 -evm v4l2src num-buffers=-1 do-timestamp=true !
 image/jpeg,width=640,height=480,framerate=30/1  ! jpegparse  ! omxmjpegdec
 \
! videoconvert ! omxh264enc target-bitrate=2000000 control-rate=variable  !
h264parse ! video/x-h264,profile=high,framerate=30/1\
! flvmux streamable=true ! queue max-size-buffers=0 max-size-time=0
max-size-bytes=0 ! rtmpsink location='rtmp://<<ip>>:1935/live2myStream
live=1'

As far I know negative jitter is good hint and based on the proportion is
operation twice of the required speed.

I attached the log file with all the bus message.

Hope someone can help.

Thanks in advance,
Joao.
