This is the pipeline which i have used to playback the file. It works fine.gst-launch -v filesrc location=/root/GStremerDir/gstreamer-0.10.13/ed24p_00.ts ! ffdemux_mpegts ! ffdec_mpeg2video ! queue ! videoscale ! ffmpegcolorspace ! xvimagesink Same thing i tried to do using the code but it doesnt play.my code is like..#include#define SOURCE "filesrc"#define VSINK "xvimagesink"#define ASINK "alsasink"#include #include //#include #include #include const gchar * location = "file:///root/GStremerDir/ed24p_00.ts";static
