Pipeline to simulate playbin stalling

[Subodh Chiwate]

Hi,
I am using IMX6 Quad board with yocto based linux and gstreamer-1.2.3.
My setup uses HDMI monitor for both Audio and video playback.

As an experiment I am trying to simulate playbin using separate Audio and video elementary streams as input.
But the pipeline gets into a stalled state, neither crashes nor proceeds with any errors.
Also the alsasink demands a audioconvert with ac3/aac decoders (libav) in 1.0.
But I want to have the audio too decoded on HDMI monitor.
( I did notice the updated capabilities of alsasink to handle ac3 in 1.0. But I am afraid, I could not figure out a way to benefit from them.)
A similar pipeline works for me using gst-0.10 and playsink ( as streamsynchronizer is not available explicitly there).

Please suggest if there is a better way to accomplish what I am trying to do with gst-1.0.

root at imx6qsabresd:~# gst-launch-1.0 -v filesrc location="/mnt/Media/gst-files/audio.m4a" ! ac3parse ! avdec_ac3 ! audioconvert ! streamsynchronizer name="ss" ss.sink_1  ss.src1 ! alsasink   filesrc location="/mnt/Media/gst-files/video.m4v" ! h264parse ! queue ! vpudec frame-drop=false ! input-selector ! ss. ss. ! imxv4l2sink
