hi,i think you should try with fluendo mpegts demuxer.you can download it from fluendo site free of cost.cheers!digitaldsp --- On Tue 09/25, sangita pithadia < sangitapithadia at gmail.com > wrote:From: sangita pithadia [mailto: sangitapithadia at gmail.com]To: gstreamer-devel at lists.sourceforge.netDate: Tue, 25 Sep 2007 12:18:19 +0000Subject: [gst-devel] gstreamer problemHi,I m trying to play MPEG TS using gstreamer pipeline. 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
