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@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 Output messages : ============ Setting pipeline to PAUSED ...
