PLAY -> PAUSE -> PLAY hickup?
Locked
 
|
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® Parallel Studio Eval Try the new software tools for yourself.

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. 2010/3/14 Georg Sauthoff <[hidden email]> Hi, ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.

I reported the same problem on 12 Jan and reg added that he too has observed this problem. I am also on Ubuntu 9.10 with 0.10.25 and reg is on Gentoo. -- Jeffrey Barish ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.

Hi,
It looks like similar case with https://bugzilla.gnome.org/show_bug.cgi?id=607842 which I reported. The patch was applied to version 0.10.26 by Wilm Taymans. You can test with version after 0.10.25 or separate patch. Thank you. 2010/3/16 Georg Sauthoff <[hidden email]>
