Lauri Lehtinen	c86d662b23	basecamerabinsrc: Handle errors from preview pipeline ... Implements a message handling function to preview pipeline bus. If GST_MESSAGE_ERROR is seen, considers preview pipeline unable to do its job and posts an error message to application. Sets pipeline element to NULL so that subsequent calls to post_preview and set_caps functions just returns without pushing anything to the disposed preview pipeline. Leaves further actions to the application.	2011-05-16 18:08:39 -03:00
Lauri Lehtinen	802028081c	basecamerabinsrc: Protection for previewpipeline when setting new preview caps ... Implements a state indicating flag to preview pipeline, so that new caps are not set if the pipeline is processing a preview. The caps are set as pending and applied when the next preview post is called. In this case a wait was implemented in the post_preview function, so that new preview image buffer will wait until the other previews have been posted to the application and the new caps can be used safely.	2011-05-16 18:08:39 -03:00
