Guillaume Desmottes f5855d50ad videometa: add support for downstream parameters to ROI meta ... The current GstVideoRegionOfInterestMeta API allows elements to detect and name ROI but doesn't tell anything about how this information is meant to be consumed by downstream elements. Typically, encoders may want to tweak their encoding settings for a given ROI to increase or decrease their quality. Each encoder has its own set of settings so that's not something that can be standardized. This patch adds encoder-specific parameters to the meta which can be used to configure the encoding of a specific ROI. A typical use case would be: source ! roi-detector ! encoder with a buffer probe on the encoder sink pad set by the application. Thanks to the probe the application will be able to tell to the encoder how this specific region should be encoded. Users could also develop their specific roi detectors meant to be used with a specific encoder and directly putting the encoder parameters when detecting the ROI. https://bugzilla.gnome.org/show_bug.cgi?id=793338		2018-02-21 12:30:10 -05:00
