I am having an issue with one of my pipelines on Windows. I attached an SVG file which shows my pipeline at the point in time when it gets stuck. The issue occurs when I try to move my pipeline from READY to PAUSED. I do this by calling gst_element_set_state(gstPipeline, GST_STATE_PAUSED), and after that call is made, I see all elements within the pipeline transition to PAUSED except the <b>GstFileSink which remains stuck in READY</b>.<o:p></o:p></p> </div> <div> <p class="MsoNormal"><o:p> </o:p></p> </div> <div> <p class="MsoNormal">Also:<o:p></o:p></p> </div> <div> <ul type="disc"> <li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1"> The issue does not repro on Linux (only Windows).<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1"> I use the same basic code to render many other kinds of jobs and I never have a problem with the GstFileSink.
