gstreamer shmsrc and shmsink with h264 data

[anjo]

i am trying to share an h264 encoded data from gstreamer to another two processes(both are based on gstreamer).After some research only way i found is to use the shm plugin. this is what i am trying to do

gstreamer--->h264 encoder--->shmsink
shmrc--->process1
shmrc--->process2
i was able to get raw data from videotestsrc and webcam working. But for h264 encoded data it doesn't. this is my test pipeline

gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480,format=YUY2 !
x264enc ! shmsink     socket-path=/tmp/foo     sync=true     wait-for-
connection=false     shm-size=10000000

gst-launch-1.0 shmsrc socket-path=/tmp/foo ! avdec_h264 ! video/x-
raw,width=640,height=480,framerate=25/1,format=YUY2 !   autovideosink
 but this dosn't work and the shmsrc pipeline always closes.
have anyone tried shm plugins with h264 encoded data, please help. Any examples would be fine

Hello Anjo,

Below pipelines is working for me.

gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480 !  x264enc key-int-max=30 ! shmsink socket-path=/tmp/foo sync=true   wait-for-connection=false

gst-launch-1.0 shmsrc socket-path=/tmp/foo ! capssetter caps=video/x-h264 ! h264parse ! avdec_h264  !  videoconvert ! videoscale ! autovideosink

Following are the errors in your pipeline.
encoder pipeline: x264enc doesn't supports YUY2.

Decode pipeline: avdec_h264 doesn't know the incoming stream type, force it to h264 by adding caps setter. add h264parse to get framed data to decoder.
