[gst-devel] Short gap in audio when unpausing

[Ben "The Big" Demboski]

Hi all.

I am playing around with gstreamer-0.10, and am noticing a gap in audio
playback immediately after un-pausing. In order to remove as much of my code
as possible from the picture, I applied the following patch to gst-launch.c
and reproduced it there:

326a327,328
> static gboolean user_pause = FALSE;
> 
332a335
>       user_pause = FALSE;
336,337c339,341
<       g_print ("Caught SIGUSR2 - Stop request.\n");
<       gst_element_set_state (pipeline, GST_STATE_NULL);
---
>       g_print ("Caught SIGUSR2 - Pause request.\n");
>       user_pause = TRUE;
>       gst_element_set_state (pipeline, GST_STATE_PAUSED);
457c461,462
<         if (!(old == GST_STATE_PLAYING && new == GST_STATE_PAUSED &&
---
>         if (user_pause ||
>             !(old == GST_STATE_PLAYING && new == GST_STATE_PAUSED &&

Running

gst-launch filesrc location=<my ogg-vorbis file> ! oggdemux ! vorbisdec !
audioconvert ! alsasink

or

gst-launch filesrc location=~/fromWin/Tribute.mp3 ! mad ! alsasink

produces the following behavior: 

--playback begins as expected
--after sending process SIGUSR2, playback pauses as expected
--after sending process SIGUSR1, playback resumes, I hear about .1 seconds
of audio, .1 seconds of silence, then audio continues as expected

Has anybody seen this, or does anybody have any idea what's going wrong?
Thanks.
