Original commit message from CVS: 2004-01-23 Julien MOUTTE <julien@moutte.net> * gst-libs/gst/play/gstplay.c: (gst_play_pipeline_setup), (gst_play_set_location), (gst_play_seek_to_time), (gst_play_set_audio_sink), (gst_play_set_visualization), (gst_play_connect_visualization), (gst_play_get_sink_element): Reworked the pipeline from scratch. Visualization is back and switch went out as i realized it was not possible to use the way i wanted. * sys/ximage/ximagesink.c: (gst_ximagesink_imagepool_clear), (gst_ximagesink_change_state), (gst_ximagesink_dispose): Move xcontext clearing in state change from READY to NULL. So that one can clean the X ressources keeping the element. * sys/xvimage/xvimagesink.c: (gst_xvimagesink_xcontext_get), (gst_xvimagesink_imagepool_clear), (gst_xvimagesink_change_state), (gst_xvimagesink_colorbalance_set_value), (gst_xvimagesink_colorbalance_get_value), (gst_xvimagesink_set_property), (gst_xvimagesink_dispose), (gst_xvimagesink_init): Same xcontext cleaning than ximagesink in state change from READY to NULL and fixed some stupid bugs in colorbalance get/set values. Also added the following feature : when nobody tries to set some values to the colorbalance levels before the xcontext is grabbed, then when creating channels list from Xv attributes we set the internal values to the Xv defaults. This way we handle buggy Xv drivers that set default hue values far from the middle of the range (Thanks to Jon Trowbridge for pointing that issue). * sys/xvimage/xvimagesink.h: Adding a cb_changed boolean to know if colorbalance levels have been set before xcontext is grabbed.
