Hi, <div class="gmail_quote">On Wed, Nov 3, 2010 at 8:24 PM, HaroldJRoth <<a href="mailto:dlafferty@gmail.com">dlafferty@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> I'm working with a custom plugin that extends GstBaseSink. I add this and a queue to my pipeline. E.g. gst_bin_add(GST_BIN(mGstPipeline), mVideoQueue); gst_bin_add(GST_BIN(mGstPipeline), mVideoSnoop); gst_element_link(mVideoQueue, mVideoSnoop); I link this queue/GstBaseSink pair to a decodebin2 manually when a video pad appears. E.g. mDecoderOutput = gst_element_factory_make("decodebin2", "decoder"); g_signal_connect(mDecoderOutput, "new-decoded-pad", G_CALLBACK(cb_newpad), this); The difficulty I find is that my GstBaseSink causes the pipeline to pause. It doesn't grab the buffers and so the queue fills up. This pauses the stream both upstream and downstream. What I'm wondering is whether this is a) Because I'm using an appsrc, but I'm not setting the timestamp properly. </blockquote><div> likely basesink is dropping the buffers. What if you sent your sink's property "sync" to false? </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> E.g.

(Don't know what the code would look like) </blockquote><div> I'm not a great expert about dynamic pipelines, but afaik you should add all the elements when the pipeline is in NULL (or PAUSED) state, then trigger the state changes to PLAYING. At least in my experience, violations may bring you to unpredictable results (and extra-hackish-code to write for manually dealing with state changes).
