This was just a test to confirm my suspicions.<br> <br> The fundamental problem here is that uridecodebin tries to calculate a buffer size based on the bitrate, but does this only once. Also, I guess the initial buffer size here of 352827 bytes might be a tad too low as well. And keep in mind that downstream's behavior also influences the buffering progress. If you see buffering percentage reverting back to somewhere around 0-5% sometimes, then this is because downstream just consumed data and emptied the queue. In some extreme cases, this can lead to pipelines that reach the PLAYING state, only for their queue2 element to suddenly get emptied again, dropping back to PAUSED state.<br> <br> I posted a proof-of-concept patch here: <a class="moz-txt-link-freetext" href="https://bugzilla.gnome.org/show_bug.cgi?id=762125"> https://bugzilla.gnome.org/show_bug.cgi?id=762125</a> though it is somewhat outdated now (I have ideas for better solutions for the documented problems).<br> <br> <div class="moz-cite-prefix">On 2016-09-04 20:13, Jonathan Miles wrote:<br> </div> <blockquote cite="mid:VI1PR0501MB235009FDEDA4F80B81AE78B9FAE70@VI1PR0501MB2350.eurprd05.prod.outlook.com" type="cite"> <style type="text/css" style="display:none;"></style> <div id="divtagdefaultwrapper" style="font-size:12pt;color:#000000;background-color:#FFFFFF;font-family:Calibri,Arial,Helvetica,sans-serif;"> <p>That stops the rebuffering, and souphttpsrc is getting a change to refill the buffer before queue2 is drained.</p> <p><br> </p> <p>Once the pipeline is into its stride:</p> <p><br> </p> <div>0:03:09.196031856 12635 0x284d50 INFO queue2 gstqueue2.c:2447:gst_queue2_locked_dequeue:<queue2-0> cur_level.bytes=3892256</div> <div>0:03:09.198157856 12635 0x3f58c0 INFO queue2 gstqueue2.c:2328:gst_queue2_locked_enqueue:<queue2-0> cur_level.bytes=4840136</div> <div>0:03:09.244743939 12635 0x3f58c0 DEBUG souphttpsrc gstsouphttpsrc.c:1640:gst_soup_http_src_read_buffer:<source> Read 977352 bytes from http input</div> <div>0:03:09.246352481 12635 0x3f58c0 DEBUG souphttpsrc gstsouphttpsrc.c:1744:gst_soup_http_src_create:<source> Returning 0 ok</div> <br> <p>Isn't 4MB a bit over the top <span style="font-size: 12pt;">for a 16/44.1 FLAC file?</span></p> </div> <hr style="display:inline-block;width:98%" tabindex="-1"> <div id="divRplyFwdMsg" dir="ltr"><font style="font-size:11pt" color="#000000" face="Calibri, sans-serif"><b>From:</b> gstreamer-devel <a class="moz-txt-link-rfc2396E" href="mailto:gstreamer-devel-bounces@lists.freedesktop.org"> <gstreamer-devel-bounces@lists.freedesktop.org></a> on behalf of Carlos Rafael Giani <a class="moz-txt-link-rfc2396E" href="mailto:dv@pseudoterminal.org"><dv@pseudoterminal.org></a><br> <b>Sent:</b> 03 September 2016 16:17:43<br> <b>To:</b> <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org"> gstreamer-devel@lists.freedesktop.org</a><br> <b>Subject:</b> Re: Audio dropouts that disappear when queue2 logging is enabled</font> <div> </div> </div> <div>How is the pipeline behavior with this?

I've had this problem with FLAC before. The two most common reasons for this (which I've observed) were: (1) queue2 figured out a size that is too low because it looked at the incoming data rate, which just happened to be low at this moment (2) uridecodebin got a bogus bitrate from the FLAC parser that is way too low (can happen with FLACs that start with silence), so it calculates a small size based on that.<br> <br> <div class="moz-cite-prefix">On 2016-09-02 17:05, Jonathan Miles wrote:<br> </div> <blockquote cite="mid:VI1PR0501MB235052587BA3C6568C43EC59FAE50@VI1PR0501MB2350.eurprd05.prod.outlook.com" type="cite"> <style type="text/css" style="display:none;"></style> <div id="divtagdefaultwrapper" style="font-size:12pt;color:#000000;background-color:#FFFFFF;font-family:Calibri,Arial,Helvetica,sans-serif;"> <div>Here's the info from the identity element:</div> <div><br> </div> <div>/GstPipeline:pipeline0/GstIdentity:identity0: last-message = chain ******* (identity0:sink) (18432 bytes, dts: none, pts: 0:00:51.408979591, duration: 0:00:00.104489796, offset: -1, offset_end: -1, flags: 00000000 ) 0xb4180df8</div> <div>/GstPipeline:pipeline0/GstIdentity:identity0: last-message = chain ******* (identity0:sink) (18432 bytes, dts: none, pts: 0:00:51.513469387, duration: 0:00:00.104489796, offset: -1, offset_end: -1, flags: 00000000 ) 0xb4f2ec10</div> <div>Buffering, setting pipeline to PAUSED ...</div> <div>Done buffering, setting pipeline to PLAYING ...</div> <div>/GstPipeline:pipeline0/GstIdentity:identity0: last-message = chain ******* (identity0:sink) (18432 bytes, dts: none, pts: 0:00:51.617959183, duration: 0:00:00.104489796, offset: -1, offset_end: -1, flags: 00000000 ) 0xb4f12200</div> <div>/GstPipeline:pipeline0/GstIdentity:identity0: last-message = chain ******* (identity0:sink) (18432 bytes, dts: none, pts: 0:00:51.722448979, duration: 0:00:00.104489796, offset: -1, offset_end: -1, flags: 00000000 ) 0xb4f2e990</div> <div>/GstPipeline:pipeline0/GstIdentity:identity0: last-message = chain ******* (identity0:sink) (18432 bytes, dts: none, pts: 0:00:51.826938775, duration: 0:00:00.104489796, offset: -1, offset_end: -1, flags: 00000000 ) 0xb43d18f0</div> <br> </div> <hr style="display:inline-block;width:98%" tabindex="-1"> <div id="divRplyFwdMsg" dir="ltr"><font style="font-size:11pt" color="#000000" face="Calibri, sans-serif"><b>From:</b> gstreamer-devel <a moz-do-not-send="true" class="moz-txt-link-rfc2396E" href="mailto:gstreamer-devel-bounces@lists.freedesktop.org"> <gstreamer-devel-bounces@lists.freedesktop.org></a> on behalf of Carlos Rafael Giani <a moz-do-not-send="true" class="moz-txt-link-rfc2396E" href="mailto:dv@pseudoterminal.org"> <dv@pseudoterminal.org></a><br> <b>Sent:</b> 02 September 2016 15:55:25<br> <b>To:</b> <a moz-do-not-send="true" class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org"> gstreamer-devel@lists.freedesktop.org</a><br> <b>Subject:</b> Re: Audio dropouts that disappear when queue2 logging is enabled</font> <div> </div> </div> <div> <p>It is possible that downstream consumes the entire buffered data in one go.
