(this is more for those who may be traveling down the path i am than for informing you specifically) <ul> <li>Got libmpeg2 code, built it;  BTW: libmpeg2 must be built in Multithreaded mode if you are using VisualStudio 2005 - otherwise linking the lib with mpeg2dec will give a link error on libcd.lib. </li> <li>then (after much searching) found mpeg2dec in the ext folder under gst-plugins-ugly.  Built that as Win32 DLL and</li> <li> copied it to GST_PLUGIN_PATH folder; </li> <li>removed the registry file and ran inspect to verify that mpeg2dec was available.</li> </ul> Then i tried the playbin using: <blockquote><tt>gst-launch-0.10.exe playbin uri=<a class="moz-txt-link-rfc2396E" href="file:///c:/dvds/Aeon_Flux.mpg">"file:///c:/dvds/Aeon_Flux.mpg"</a></tt> </blockquote> This worked.   However the CPU Usage oscillated between 40% to 60%+.  One of my reasons for looking at gstreamer was to cut down the cpu utilization on software decoding.  Any hints on how to do this??  The machine is a Intel Dual Core 2CPU, 2.00GHz, with 2GB RAM. BTW: Aeon_Flux.mpg is Mpeg-2 ts with MP2 audio -- its not h.264 or other formats; its the trailer to Aeon Flux the movie. Thinking that it maybe due to queues/buffers, i tried the following pipelines and none work. BTW: i did copy the old pipelines with the { and tried to embelish them... as I reported, a) they were on the man pages -- which did not mention specific 0.10 or 0.8 version) and b) 'cause Julien recommended it, c) 'cause all/any pipeline examples on devel have them. Pipelines that don't work: <blockquote><tt>C:\downloads\gstreamer>gst-launch-0.10.exe filesrc location="c:/dvds/Aeon_flux.mpg" ! flutsdemux name="d" .video_00 !mpe</tt><tt>gvideoparse ! mpeg2dec! ffmpegcolorspace ! directdrawsink ! d.audio_00 !queue ! mp3parse ! dshowadec_mpeg1 ! autoaudiosi</tt><tt>nk</tt> <tt>** (gst-launch-0.10:5212): WARNING **: error while parsing</tt> <tt>WARNING: erroneous pipeline: link without source element</tt> </blockquote> Guess the problem with the above pipeline is that i was trying to link directdrawsink to d.audio_00, sooo..... (removed the ! 'tween directdrawsink and d.audio_00) <blockquote><tt>C:\downloads\gstreamer>gst-launch-0.10.exe filesrc location="c:/dvds/Aeon_flux.mpg" ! flutsdemux name="d" .video_00 !mpe</tt><tt>gvideoparse ! mpeg2dec! ffmpegcolorspace ! directdrawsink  d.audio_00 !queue ! mp3parse ! dshowadec_mpeg1 ! autoaudiosin</tt><tt>k</tt> <tt>Setting pipeline to PAUSED ...</tt> <tt>Pipeline is PREROLLING ...</tt> <tt>^C</tt> <tt>C:\downloads\gstreamer>gst-launch-0.10.exe filesrc location="c:/dvds/Aeon_flux.mpg" ! flutsdemux name="d" .video_00 ! qu</tt><tt>eue ! mpegvideoparse ! mpeg2dec! ffmpegcolorspace ! directdrawsink  d.audio_00 !queue ! mp3parse ! dshowadec_mpeg1 ! aut</tt><tt>oaudiosink</tt> <tt>Setting pipeline to PAUSED ...</tt> <tt>Pipeline is PREROLLING ...</tt> <tt>^C </tt></blockquote> That helped with the error, but it did not render either audio or video. <blockquote><tt>C:\downloads\gstreamer>gst-launch-0.10.exe filesrc location="c:/dvds/Aeon_flux.mpg" ! flutsdemux name="d" .video_00 ! qu</tt><tt>eue ! mpegvideoparse ! mpeg2dec! ffmpegcolorspace ! directdrawsink</tt> <tt>Setting pipeline to PAUSED ...</tt> <tt>Pipeline is PREROLLING ...</tt> <tt>^C </tt></blockquote> your email reply says to use single quotes instead of double quotes... so altered to that... but " seems to be what works in Win32. <blockquote><tt>C:\downloads\gstreamer>gst-launch-0.10.exe filesrc location="c:/dvds/Aeon_flux.mpg" ! flutsdemux name='d' .video_00 ! qu</tt><tt>eue ! mpegvideoparse ! mpeg2dec! ffmpegcolorspace ! directdrawsink  d.audio_00 !queue ! mp3parse ! dshowadec_mpeg1 ! aut</tt><tt>oaudiosink</tt> <tt>WARNING: erroneous pipeline: No element named "d" - omitting link</tt> </blockquote> Well... trying with just video... and nada! <blockquote><tt>C:\downloads\gstreamer>gst-launch-0.10.exe filesrc location="c:/dvds/Aeon_flux.mpg" ! flutsdemux name="d" .video_00 ! qu</tt><tt>eue ! mpegvideoparse ! mpeg2dec! ffmpegcolorspace ! directdrawsink</tt> <tt>Setting pipeline to PAUSED ...</tt> <tt>Pipeline is PREROLLING ...</tt> <tt>^C</tt> </blockquote> This pipeline specification on command line, the lack of correct documentation of 10.x etc. makes adoption of gstreamer quite challenging!  I'm glad for the devel assistance and at times feel that basics are missing... its not that i want "hand-holding", not understanding the impl begs for much trial and error, lost time and perhaps PITA q's on devel to those who are in "the Know". Unless I'm able to get the CPU usage down drastically, i can't see myself using gstreamer... since i want a win32 solution, maybe i'll go with directx.  will see... hoping that there are some silver bullet answers ;-) kindest regards, s- Wim Taymans wrote: <blockquote cite="mid:1203673254.7179.41.camel@metal" type="cite"> <pre wrap="">On Thu, 2008-02-21 at 17:42 -0700, Sheshadri Mantha wrote: </pre> <blockquote type="cite"> <pre wrap="">OK here is what I've tried. * Using simply playbin as: gst-launch-0.10.exe playbin uri=<a class="moz-txt-link-rfc2396E" href="file:///c:/dvds/Aeon_Flux.mpg">"file:///c:/dvds/Aeon_Flux.mpg"</a>.
