Hi, This message was originally posted on the Nabble mailing lists, but I can now provide more information. To re-cap I have flac files that I can playback using playbin2 uri=file:/// , but when I try to stream these files using playbin2 uri=http:// I get the following error: ERROR: from element /GstPlayBin2:playbin20/<div id=":6n">GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source: Internal data flow error. Additional debug info: gstbasesrc.c(2507): gst_base_src_loop (): /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source: streaming task paused, reason error (-5) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... This is using Ubuntu 10.04, with lighttpd as the web server. On the same machine I have a load of other flac files that all stream perfectly. I was asked to increase the debug level and provide all of the output, I have included the area that I think is important and attached the file. One of the offending flac files is also attached. Although the issue is evident on my Ubuntu machine, I really want this to work on an arm embedded system. If I need to report this as a bug please tell me how I should do that. Also where can I upload the flac file to? Thanks, Stuart </div>
