HI Felipe, If I use following pipe line it will work fine. "gst-launch-0.10 filesrc location=/media/mmcblk0p1/Movie.mp4 ! mpeg4parser ! mpeg4dec ! ffmpegcolorspace ! fbdevsink" Here mpeg4parser and mpeg4dec are my Plugins which I made. Capability of both are as followed. MPEG4PARSER :: ============ SINK template: 'sink' Availability: Always Capabilities: video/picus-mpeg4parser width: [ 1, 2147483647 ] height: [ 1, 2147483647 ] framerate: [ 0/1, 2147483647/1 ] mpegversion: 4 systemstream: false SRC template: 'src' Availability: Always Capabilities: video/picus-mpeg4dec MPEG4DEC :: ========= Pad Templates: SINK template: 'sink' Availability: Always Capabilities: video/picus-mpeg4dec width: [ 1, 2147483647 ] height: [ 1, 2147483647 ] framerate: [ 0/1, 2147483647/1 ] SRC template: 'src' Availability: Always Capabilities: video/x-raw-yuv Src pad of mpeg4dec will be connected with ffmpegcolorspace and later will be connected with fbdevsink and complete pipeline will be settled. But instead fbdevsink if I use omapfbsink I can not create pipeline and getting following error. -Tejas. -----Original Message----- From: Felipe Contreras [mailto:felipe.contreras at gmail.com] Sent: Wednesday, February 17, 2010 4:19 PM To: Tejas Cc: gstreamer-embedded at lists.sourceforge.net Subject: Re: Need Help In Totem Media Player On Fri, Feb 12, 2010 at 7:46 AM, Tejas <tejas at picus.in> wrote: > I have built omapfbsink plugin from openembedded and taken it o my my library path and then I have created following pipe line. > > " gst-launch-0.10 filesrc location=/media/mmcblk0p1/Movie.mp4 ! mpeg4parser ! mpeg4dec ! ffmpegcolorspace ! omapfbsink " I'm not sure 'mpeg4parser' is the right element, probably you want qtdemux. > It gives following error. > > "ERROR: Pipeline doesn't want to pause." > > Here mpeg4dec gives output in the form of I420. > > Where is the problem ? You can try to run with this: export GST_DEBUG=2 To find out warnings and errors. -- Felipe Contreras
