This useless high-res + processing for 9 preview images in parallel brings my 2nd gen + core i5 @ 3.1 GHz to its knees, resulting in a non fluid preview panel. + + Also after clicking through all effect preview pages, so that all effect + preview textures are connected, cheese will use 1 GB of *resident* RAM + with the example 1280x800 capture resolution. + + This patch improves this by downscaling the images from the video-source + to 640xXXX where XXX is determined by the original resolution + aspect-ratio. + + After this patch the effects preview framerate is much smoother, and the + latency is noticably less. As a bonus the maximal resident size of + Cheese in this example is reduced to 350 MB. + - Do not block the main valve while recording + Otherwise frames intended for the recording are dropped. + - Only add videoconvert elements where necessary + The "no effect" effect is our default value, and thus worth optimizing a + bit. Clearly in the "no effect" effect case adding a videoconvert + element both before and after the element is not needed. + + Note we also don't add the videoconvert elements when creating the + initial pipeline, so this also keeps the way the pipeline looks + initially and when "no-effect" is selected consistent. + + When starting Cheese with "no-effect" selected, this shaves off another + 130 ms of the initial pipeline creation time. + - Drop unused preview_caps variable + - Simplify returned GstCaps + In cheese_camera_device_get_caps_for_format, simplify the returned caps. + This results in much simpler caps, which as main advantage that they are + way easier to read when trawling to debug logs. + - Fix cheese_camera_device_get_best_format memleak + cheese_camera_device_get_best_format() calls + cheese_camera_device_get_format_list(), which returns a sorted copy of + the format lists, then takes the first element of that list, and + returns a copy of that element. While never freeing the list copy. + + This patch fixes this leak by simply making the priv->formats list + sorted so that cheese_camera_device_get_best_format can use it directly + without the need to make (and then later free) a copy. + - Fix cheese_camera_device_filter_caps warning + - Remove unused GstCameraBinFlags enum + - Fix video-source memleak when switching cameras + - Improve error handling in CheeseCamera + Simplify error cleanup in cheese_camera_set_camera_source(). Do not call + g_error_free() on a possible NULL error in + cheese_camera_element_from_effect(). + - Fix no-video-after-switching-resolution problem + There is a bug in wrappercamerabinsrc which causes it to lose its + video-source setting after the pipeline has started, so on a + stop/re-start, as when changing resolution, its video-source has become + NULL, and there is no longer video. + + This patch works around this by moving the setting of the video-source + property to cheese_camera_play(), so that it gets (re)set each time + before starting the pipeline. + + I've also written a patch fixing the underlying cause, but since the + workaround is simple, and has no adverse effects when the underlying + issue is fixed, it seems a good idea to have this workaround in Cheese, + see here for the gst-plugins-bad fix: + + https://bugzilla.gnome.org/show_bug.cgi?id=701915 + - Remove extranous csp_post_balance element + camerabin2 already has a videoconvert element both before and after its + video-source-filter element, so ending the video-source-filter bin with + a videoconvert element puts 2 videoconvert elements behind each other, + which is not really useful. + - Add a capsfilter to the video-source bin + This serves 2 purposes. Firstly, it forces GStreamer to actually run the + video source at the configured resolution, rather then say run it at + 1600x1200 @ 5 fps and downscale that to 800x600 (still at 5 fps), as + GStreamer opts to do with my Logitech Webcam Pro 9000, when left to its + own auto negotiate code. Secondly, by greatly reducing the amount of + advertised caps (this cam supports lots of different resolutions at many + different framerates per resolution), it avoids a caps intersect + "explosion", reducing the pipeline caps negotiation. + - Remove nautilus-sendto sharing support + As nautilus-sendto can now only share by email, the sharing can be + handled by a photo management application, or directy by the email + client. + - Avoid assert when taking avatar photos too quickly + If the take photo button was pressed while a photo was being taken, an + assert would be triggered by the failed call to + cheese_camera_take_photo_pixbuf(). Avoid this by setting the take photo + button insensitive while a photo is being taken, and setting it + sensitive after the photo has been taken.
