* SECTION:gstvideoencoder
|
|
* @title: GstVideoEncoder
|
|
* @short_description: Base class for video encoders
|
|
*
|
|
* This base class is for video encoders turning raw video into
|
|
* encoded video data.
|
|
*
|
|
* GstVideoEncoder and subclass should cooperate as follows.
|
|
*
|
|
* ## Configuration
|
|
*
|
|
* * Initially, GstVideoEncoder calls @start when the encoder element
|
|
* is activated, which allows subclass to perform any global setup.
|
|
* * GstVideoEncoder calls @set_format to inform subclass of the format
|
|
* of input video data that it is about to receive. Subclass should
|
|
* setup for encoding and configure base class as appropriate
|
|
* (e.g. latency). While unlikely, it might be called more than once,
|
|
* if changing input parameters require reconfiguration. Baseclass
|
|
* will ensure that processing of current configuration is finished.
|
|
* * GstVideoEncoder calls @stop at end of all processing.
|
|
*
|
|
* ## Data processing
|
|
*
|
|
* * Base class collects input data and metadata into a frame and hands
|
|
* this to subclass' @handle_frame.
|
|
*
|
|
* * If codec processing results in encoded data, subclass should call
|
|
* @gst_video_encoder_finish_frame to have encoded data pushed
|
|
* downstream.
|
|
*
|
|
* * If implemented, baseclass calls subclass @pre_push just prior to
|
|
* pushing to allow subclasses to modify some metadata on the buffer.
|
|
* If it returns GST_FLOW_OK, the buffer is pushed downstream.
|
|
*
|
|
* * GstVideoEncoderClass will handle both srcpad and sinkpad events.
|
|
* Sink events will be passed to subclass if @event callback has been
|
|
* provided.
|
|
*
|
|
* ## Shutdown phase
|
|
*
|
|
* * GstVideoEncoder class calls @stop to inform the subclass that data
|
|
* parsing will be stopped.
|
|
*
|
|
* Subclass is responsible for providing pad template caps for
|
|
* source and sink pads. The pads need to be named "sink" and "src". It should
|
|
* also be able to provide fixed src pad caps in @getcaps by the time it calls
|
|
* @gst_video_encoder_finish_frame.
|
|
*
|
|
* Things that subclass need to take care of:
|
|
*
|
|
* * Provide pad templates
|
|
* * Provide source pad caps before pushing the first buffer
|
|
* * Accept data in @handle_frame and provide encoded results to
|
|
* @gst_video_encoder_finish_frame.
|
|
*
|
|
*
|
|
* The #GstVideoEncoder:qos property will enable the Quality-of-Service
|
|
* features of the encoder which gather statistics about the real-time
|
|
* performance of the downstream elements. If enabled, subclasses can
|
|
* use gst_video_encoder_get_max_encode_time() to check if input frames
|
|
* are already late and drop them right away to give a chance to the
|
|
* pipeline to catch up.
