The duration in ClutterMedia is currently expressed in integer multiples
of a second. This does not offer enough granularity for media playback
that has fractionary durations -- 2.3 seconds; 1 minute, 23.4 seconds;
1 hour, 23 minutes, 4.5 seconds; etc.
The duration value should be expressed in seconds with a sub-second
granularity; for this reason, a double should be used insted of an
unsigned integer.
The semantics haven't changed: the :duration property still exposes
seconds.
ClutterMedia was a rough cut at a simple media API; it needs some
re-evaluation before 1.0 in order to keep it simple to use, and
simple to implement.
- ClutterMedia:position
The position property accessors collide with the corresponding
ClutterActor methods, which make it impossible to bind them in
high-level languages:
video_texture.set_position()
video_texture.get_position()
In order to resolve the collision, we have to go through the
GObject properties API:
video_texture.set('position', value)
value = video_texture.get('position')
A :position in seconds is also a GStreamer-ism, and should rather
be converted to a :progress property, with a normalized value
between 0 and 1. the current position in seconds would then simply
be progress*duration. For non-seekable streams, 0.0 would always
be returned. This makes it easier to use the progress inside
animations, Timelines or ClutterPath instances.
- ClutterMedia:volume should be renamed to :audio-volume and normalized
as well, instead of being a floating point value between 0 and 100.
- ClutterMedia:buffer-percent should just be :buffer-fill and normalized
between 0.0 and 1.0
* clutter/clutter-media.c: Document ClutterMedia signals;
replace the implementation of clutter_media_set_filename() with
something a wee bit more robust (and portable) than a sprintf().
* clutter/clutter-media.c: (clutter_media_base_init):
Remove #if 0! signal - assume causing issues with binding generation.
(#407)
* clutter/cogl/gl/cogl.c:
Check GL_TEXTURE_RECTANGLE_ARB and GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB
are defined in gl.h (#404)
