<div dir="ltr">You need to turn on logging to find where it is stopping. In Linux, export GST_DEBUG=*:3 or something like that, maybe even 4 or 5. The higher numbers give much more logging. </div><div class="gmail_extra"> <div class="gmail_quote">On Thu, Mar 6, 2014 at 7:36 AM, krupa <<a href="mailto:krupa.gopal@gmail.com" target="_blank">krupa.gopal@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi, I'm trying to SEEK in my plugin which is pull based(a parser). Right now I have implemented just the 'loop' function and 'src_event' function. I have an application calling seek as below. gst_element_seek (pipeline, 1.0, GST_FORMAT_TIME,GST_SEEK_FLAG_FLUSH, GST_SEEK_TYPE_SET, time_nanoseconds, GST_SEEK_TYPE_NONE,GST_CLOCK_TIME_NONE) *time_nanoseconds will be current playing time + 1ns In the seek switch of the src_event I have implemented the seek as follows. 1) gst_pad_push_event (myplugin->sinkpad, gst_event_new_flush_start ()); 2) gst_pad_push_event (myplugin->srcpad, gst_event_new_flush_start ()); 3) GST_PAD_STREAM_LOCK (myplugin->sinkpad); 4) Call library function to do the seek. 5) gst_pad_push_event (myplugin->sinkpad, gst_event_new_flush_stop ()); 6) gst_pad_push_event (myplugin->srcpad, gst_event_new_flush_stop ()); 7) GST_PAD_STREAM_UNLOCK (myplugin->sinkpad); After the seek event comes, my pipeline freezes. From what I understand GST_PAD_STREAM_LOCK (myplugin->sinkpad) is not able to get a lock. Statements after this statement aren't getting executed. Even if I remove it, the pipeline freezes. I wanted to know what GST_PAD_STREAM_LOCK does and also how to implement seeking in a plugin driving the pipeline and what happens when seek is called.
