I am trying to fiddle with the playback rate but haven't been able to make the video go slower or faster. Anyone know how to do this?
Tried:
1. gst_element_seek();
2.
/* Create the seek event */
if (playRate > 0) {
seek_event =
gst_event_new_seek(playRate, GST_FORMAT_TIME,
(GstSeekFlags)(GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_ACCURATE), GST_SEEK_TYPE_SET,
gPosition, GST_SEEK_TYPE_END, 0);
}
else {
seek_event =
gst_event_new_seek(playRate, GST_FORMAT_TIME,
(GstSeekFlags)(GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_ACCURATE), GST_SEEK_TYPE_SET, 0,
GST_SEEK_TYPE_SET, gPosition);
}
if (video_sink == NULL) {
/* If we have not done so, obtain the sink through which we will send the seek events */
g_object_get(G_OBJECT(gespipeline), "video-sink", &video_sink, NULL);
}
if (audio_sink == NULL) {
/* If we have not done so, obtain the sink through which we will send the seek events */
g_object_get(G_OBJECT(gespipeline), "audio-sink", &audio_sink, NULL);
if(audio_sink != NULL)
{
gboolean mute = (playRate > 1.0)?TRUE:FALSE;
g_object_set(G_OBJECT(audio_sink), "mute",mute, NULL);
}
}
/* Send the event */
// tried the gespipeline and the gst_element(gespipeline) that has the main pipe.
GstElement* pipeline = (GST_ELEMENT(gespipeline)) / gespipeline;
gst_element_send_event(pipeline, seek_event);
