Which architecture do you find this issue? X86 platform or arm platform. I have found a similar issue on arm platform, and it is caused by a wrong return value of snd_pcm_delay() in the playing->pause state change. This causes a bigger base time when the pipeline changes from pause to playing. <div class="gmail_quote">2010/3/14 Georg Sauthoff <<a href="mailto:g_sauthoff@web.de">g_sauthoff@web.de</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi, while using the gstreamer API I noticed some playback-hickups if a paused pipeline is resumed: set_state(pipeline, GST_STATE_PLAYING); // listen some time set_state(pipeline, GST_STATE_PAUSED); // let the event loop wait some seconds set_state(pipeline, GST_STATE_PLAYING); => after the last state transition to GST_STATE_PLAYING playback starts again, but with a hickup. Like this: SHORT_MUSIC SHORT_SILENCE MUSIC I tested the same mp3-file with mplayer, where play/pause transitions work as expected without hickups. I am using this pipeline playbin2 uri="file://foo.mp3" audio-sink="alsasink device=plughw:0,0" which is created via gst-launch(). Do I have to do some extra setup to get resume-from-pause without hickups? Best regards Georg PS: Using gstreamer 0.10.25 as packaged with Ubuntu 9.10. ------------------------------------------------------------------------------ Download Intel&#174; Parallel Studio Eval Try the new software tools for yourself.
