I have used "gst-launch filesrc location=0801.mpa ! decodebin ! audioconvert ! alsasink" and "gst-launch filesrc location=0800.mpv ! queue ! mpeg2dec ! ffmpegcolorspace ! xvimagesink" to successfully play the individual files, but when I combine them with gst-launch -m filesrc location=file.ts ! flutsdemux name=d  d.audio_0801 ! queue ! decodebin ! audioconvert ! alsasink  d.video_0800 ! queue ! mpeg2dec ! xvimagesink a window is opened and the first frame displayed, but neither does the video continue, nor is there any audio.  I can kill the X window, and there are the messages at the end of the post. Any ideas where I should begin debugging this?  Is there a clock/sync problem, perhaps? Thanks. Setting pipeline to PAUSED ... Pipeline is PREROLLING ...
