Hi,<div> </div><div> The problem is that we may need to scale our applications to support thousands of subscribers simultaneously. i.e, 1000s of subscribers will try to download different video files and feed to the gstreamer framework for decoding/parsing of these files. So if I need the same kind of pipeline that will just decode one video format and do something for all these video files, then do I need to create separate pipelines for all these files. </div> <div><br></div><div> Our scenario is that we may need to support decoding/parsing of these thousands of files (Or even more) simultaneously and if we need to create one pipeline per file, we'll end up creating a huge number of threads (one per pipeline) which will not be feasible. Please let me know whether this kind of scenario can be supported using gstreamer and if yes, plz suggest me the best way to achieve this.</div> <div> <br clear="all"><i><b><font color="#3366FF">Thanks & Regards</font></b><font color="#66CCCC"><b>,</b></font><b><br></b><font color="#3366FF"><b>Shibin</b></font></i><br> <br><br><div class="gmail_quote">On Tue, Nov 16, 2010 at 6:02 PM, Marco Ballesio <span dir="ltr"><<a href="mailto:gibrovacco@gmail.com">gibrovacco@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi,<br><br><div class="gmail_quote"><div class="im">On Tue, Nov 16, 2010 at 1:53 PM, shibin k <span dir="ltr"><<a href="mailto:shibin00@gmail.com" target="_blank">shibin00@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204, 204, 204);padding-left:1ex"> Hi,<div><br></div><div> Thanks for the reply. I understood that with mutiple pipelines, we can achieve multiple video sessions. But if I've hundreds of subscribers trying to download and decode/parse same or multiple video files simultaneously, we will end up creating lot of pipelines and in effect lot of threads right? This will effect the performance, isn't it? Please let me know whether gstreamer framework is scalable to achieve the scenario I've mentioned here and whether the performance will be hit during such scenario? </div> </blockquote></div><div><br>there are many excellent GStreamer - based apps scaling very well up to hundreds of threads. <br><br>One for all:<br><br><a href="http://www.buzztard.org/index.php/Main_Page" target="_blank">http://www.buzztard.org/index.php/Main_Page</a><br> <br>Afaik limits are given on how well are the custom elements in your pipeline written and on your system capacity.
