[gst-devel] GStreamer queue issue

[신승배]

Hi,

Try pipeline below, (added explicit demuxer pad)

gst-launch filesrc location=test.mpg ! mpegdemux name=demuxer
demuxer.video_00 !
queue ! mpeg2dec ! ffmpegcolorspace ! ximagesink demuxer.audio_00 ! queue !
mad !
audioconvert ! audioresample ! alsasink
