We are doing this testing on ARM platform. We have disabled ffmpegcolorspace and videoscale inside playbin code. so that our video pipeline should look similar to the one which I have mentioned in customized pipeline.</div> <div> </div> <div>gst-launch filesrc location=/media/sdmmc0p1/Comebacks.avi ! avidemux name=demux { demux.audio_00 ! queue ! omx_mp3dec ! alsasink } { demux.video_00 ! queue ! omx_h264dec ! xvimagesink } </div> <div> </div> <div> </div> <div>One more behaviour I have observed while debugging with PowerTrace hardware that playbin creates 12 threads for the following command while similar specific pipeline creates 10 thread. What are these extra 2 threads created by playbin? Is there any clue on the same?</div> <div> </div> <div>1) with playbin (12 threads)<br> <br>gst-launch playbin uri=file:///media/sdmmc0p1/Comebacks.avi<br> <br>2) with gst-launch specific pipeline (10 threads)<br> <br>gst-launch filesrc location=/media/sdmmc0p1/Comebacks.avi ! avidemux name=demux { demux.audio_00 ! queue ! omx_mp3dec ! alsasink } { demux.video_00 ! queue ! omx_h264dec ! xvimagesink } </div> <div><br>Regards,</div> <div>Manish</div> <div> </div> <div><br> </div> <div class="gmail_quote">2008/11/14 Zhao, Halley <span dir="ltr"><<a href="mailto:halley.zhao@intel.com">halley.zhao@intel.com</a>></span><br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div lang="ZH-CN" vlink="purple" link="blue"> <div> <p style="MARGIN-LEFT: 18pt; TEXT-INDENT: -18pt"><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial"><span>1.<font face="Times New Roman" size="1"><span style="FONT: 7pt 'Times New Roman'">       </span></font></span></span></font><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial">playbin will always link ffmpegcolorspace and videoscale into the pipeline, it will impact the performance compare to customized pipeline.</span></font></p> <p style="MARGIN-LEFT: 18pt; TEXT-INDENT: -18pt"><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial"><span>2.<font face="Times New Roman" size="1"><span style="FONT: 7pt 'Times New Roman'">       </span></font></span></span></font><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial">man gst-launch-0.10 you will see the option "—gst-debug=STRING", next  "gst-launch-0.10 –gst-debug-help" you will see the category</span></font></p> <p><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial">for example: </span></font></p> <p><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial">gst-launch-0.10 --gst-debug=GST_AUTOPLUG:5,xvimagesimk:5,GST_DATAFLOW:5,playbin:5 --gst-debug-no-color playbin uri=file:///home/ume/work/test.m2v </span></font></p> <p><font face="Arial" color="navy" size="1"><span lang="EN-US" style="FONT-SIZE: 9pt; COLOR: navy; FONT-FAMILY: Arial"> </span></font></p> <div style="BORDER-RIGHT: medium none; PADDING-RIGHT: 0cm; BORDER-TOP: medium none; PADDING-LEFT: 4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: blue 1.5pt solid; PADDING-TOP: 0cm; BORDER-BOTTOM: medium none"> <div> <div style="TEXT-ALIGN: center" align="center"><font face="Times New Roman" size="3"><span lang="EN-US" style="FONT-SIZE: 12pt"> <hr align="center" width="100%" size="2"> </span></font></div> <p><b><font face="Tahoma" size="2"><span lang="EN-US" style="FONT-WEIGHT: bold; FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">From:</span></font></b><font face="Tahoma" size="2"><span lang="EN-US" style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma"> Manish Sharma [mailto:<a href="mailto:manishsharma13@gmail.com" target="_blank">manishsharma13@gmail.com</a>] <br> <b><span style="FONT-WEIGHT: bold">Sent:</span></b> 2008</span></font><font face="宋体" size="2"><span style="FONT-SIZE: 10pt">年</span></font><font face="Tahoma" size="2"><span lang="EN-US" style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">11</span></font><font face="宋体" size="2"><span style="FONT-SIZE: 10pt">月</span></font><font face="Tahoma" size="2"><span lang="EN-US" style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">13</span></font><font face="宋体" size="2"><span style="FONT-SIZE: 10pt">日</span></font><font face="Tahoma" size="2"><span lang="EN-US" style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma"> 16:57<br> <b><span style="FONT-WEIGHT: bold">To:</span></b> <a href="mailto:gstreamer-devel@lists.sourceforge.net" target="_blank">gstreamer-devel@lists.sourceforge.net</a><br><b><span style="FONT-WEIGHT: bold">Subject:</span></b> [gst-devel] Performance with gst-launch pipeline and playbin</span></font><span lang="EN-US"></span></p> </div> <div> <div></div> <div class="Wj3C7c"> <p><font face="Times New Roman" size="3"><span lang="EN-US" style="FONT-SIZE: 12pt"> </span></font></p> <div> <p><font face="Times New Roman" size="3"><span lang="EN-US" style="FONT-SIZE: 12pt">Hi All,</span></font></p></div> <div> <p><font face="Times New Roman" size="3"><span lang="EN-US" style="FONT-SIZE: 12pt"> </span></font></p></div> <div> <p><font face="Times New Roman" size="3"><span lang="EN-US" style="FONT-SIZE: 12pt">While using the playbin for playback I am observing more CPU usage as compared to gstreamer customized pipeline.</span></font></p></div> <div> <p><font face="Times New Roman" size="3"><span lang="EN-US" style="FONT-SIZE: 12pt">I know that playbin adds some preroll queue before audio video sink.
