you could try taking a look at queue2 element. It allows you to set a minimum amount of data to buffer before playing. <div class="gmail_quote">On Fri, Jul 11, 2008 at 4:03 AM, Ting Wang <<a href="mailto:wangting@gmail.com">wangting@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, Ling I made a mistake, the video clip I was testing is too short to fill the qtdemux input buffer. After reading the log in neonhttpsrc I found that neonhttpsrc was constantly feeding data into qtdemux. With a long video stream, I can see that the pipeline is working while downing the file. Thank you anyway :) Best regards Felix <div class="gmail_quote">On Fri, Jul 11, 2008 at 2:53 PM, Shi Ling-w20230 <<a href="mailto:lingshi@motorola.com" target="_blank">lingshi@motorola.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div link="blue" vlink="#606420" lang="ZH-CN"> <div> Which format did you play?

I am using "neonhttpsrc" as file source. During the playback, I found out that the demux and decode process will not start until the file has been fully downloaded. What I want is that the demux and decode process should start as soon as possible and not until getting the whole file. Is there any feature which can support this or did I miss some configuration about Gstreamer? Thank you for your attention and hope you can give me some advice :) Best regards Felix </div></div></div></div></div> </div> </blockquote></div> ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
