<html><head><style type="text/css"></style></head><body><div style="font-family:'times new roman', 'new york', times, serif;font-size:12pt"><div>Hi,</div><div>thanks a lot to all people, this works fine! </div><div>Now my only concern left is to be able to reset the timestamps (start again at 0) when changing the file. Currently when I apply this solution, timestamps continue to increase (for example 0 to 2 seconds in first file, then 2 to 4 seconds in the second file when I change it). </div><div>I've tried to put a homemade plugin that offsets the timestamps back to 0 when I change the file (changing my branch to tee0. ! queue ! offsetplugin ! ffenc ! mpgtsmux ! filesink). But it seems it doen't work well: even doing that, dumping the timestamps of the second file starts at 2 seconds (with this example).</div><div>Regards,</div><div>Al</div><div style="font-family:times new roman, new york, times, serif;font-size:12pt"><br><div style="font-family:arial, helvetica, sans-serif;font-size:13px"><font size="2" face="Tahoma"><hr size="1"><b><span style="font-weight: bold;">De :</span></b> Edward Hervey <bilboed@gmail.com><br><b><span style="font-weight: bold;">À :</span></b> Discussion of the development of GStreamer <gstreamer-devel@lists.sourceforge.net><br><b><span style="font-weight: bold;">Envoyé le :</span></b> Jeu 17 juin 2010, 8h 36min 15s<br><b><span style="font-weight: bold;">Objet :</span></b> Re: [gst-devel] Changing file location during recording<br></font><br>On Wed, 2010-06-16 at 16:27 +0000, Albert Costa wrote:<br>> Hi,<br>> I have a pipeline that can be reducted to:<br>> <br>> <br>> gst-launch dshowvideosrc ! tee ! queue ! ffmpegcolorspace !<br>> ffenc_mpeg2video ! mpegtsmux ! filesink tee0. ! queue !<br>> ffmpegcolorspace ! directdrawsink<br>> <br>> <br>> All this is created/handled in a c application where I can start and<br>> stop the pipeline.

To ensure no data is flowing, use the gst_pad_set_blocked_async()<br>method on the pad feeding data to your filesink.<br><br> * Grab the mpegtsmux source pad and<br>gst_pad_set_blocked_async(sourcepad, TRUE, my_blocked_callback,<br>filesink);<br> * In your my_blocked_callback:<br> ** WHEN blocked is TRUE:<br> *** set filesink to NULL,<br> *** change the location property of filesink,<br> *** set filesink to PLAYING,<br> *** and finally call gst_pad_set_blocked_async(sourcepad, FALSE,<br>my_blocked_callback, NULL);<br><br>  Edward<br><br>P.S.
