omxh264enc and stream-format=(string)avc

Tue Apr 21 14:22:27 PDT 2015

Hi all,

@Keith, I only made your suggestion working when I added the decodbin but
the decode side has lot of issues.

Any suggestion?

GST_DEBUG=2 gst-launch-1.0 --gst-debug=flvmux:7,rtmpsink:7,omxh264enc:7
v4l2src ! decodebin name=demux ! queue ! videorate ! videoscale method=0 !
video/x-raw, framerate=30/1, width=320, height=240 ! videoconvert !
clockoverlay ! omxh264enc inline-header=true periodicty-idr=1 ! h264parse !
video/x-h264,profile=high,framerate=30/1,target-bitrate=130000 ! flvmux
streamable=true ! queue ! rtmpsink location='rtmp://
192.168.1.4:1935/live/myStream' demux. ! queue ! progressreport

Thanks in advance,
JM.
