*
* ### Supported Events
* Event | Purpose
* ----------------------------- | :----------------------------:
* #V4L2_EVENT_RESOLUTION_CHANGE | Resolution of the stream has changed.
*
* ### Handling Resolution Change Events
* When the decoder generates a \c V4L2_EVENT_RESOLUTION_CHANGE event, the
* application calls \c STREAMOFF on the capture plane to tell the decoder to
* deallocate the current buffers by calling REQBUF with count zero, get
* the new capture plane format, and then proceed with setting up the buffers
* for the capture plane.
*
* In case of decoder, the buffer format might differ from the display resolution.
* The application must use \c VIDIOC_G_CROP to get the display resolution.
*
* ### EOS Handling
* The following sequence must be followed for sending EOS and recieving EOS
* from the decoder.
* -# Send EOS to decoder by queueing on the output plane a buffer with
* bytesused = 0 for the 0th plane (`v4l2_buffer.m.planes[0].bytesused = 0`).
* -# Dequeues buffers on the output plane until it gets a buffer with bytesused = 0
* for the 0th plane (`v4l2_buffer.m.planes[0].bytesused == 0`)
* -# Dequeues buffers on the capture plane until it gets a buffer with bytesused = 0
* for the 0th plane.
*
* ### Decoder Input Frame Metadata
* Decoder supports reporting stream header parsing error info as input frame metadata.
* See \c V4L2_CID_MPEG_VIDEO_ERROR_REPORTING, \c V4L2_CID_MPEG_VIDEODEC_INPUT_METADATA
* and \c v4l2_ctrl_video_metadata for more information.
*
* ### Decoder Output Frame Metadata
* Decoder supports reporting frame related metadata, including error reports and
* DPB info. See \c V4L2_CID_MPEG_VIDEO_ERROR_REPORTING, \c V4L2_CID_MPEG_VIDEODEC_METADATA
* and \c v4l2_ctrl_video_metadata for more information.

* ### Setting Framerate
* The camera framerate can be set with \c VIDIOC_S_PARM IOCTL by setting the numerator
* and denominator in `v4l2_streamparm.parm.output.timeperframe`.
* Selection of camera mode can override this setting. If the camera mode is to be
* selected along with the specified framerate, then camera mode must be selected before
* setting the framerate.
*
* ### Camera Capture Metadata
* The camera can be queried to report frame related metadata. See \c V4L2_CID_ARGUS_METADATA
* for more information.
*
* ### EOS Handling
* Camera outputs all the queued empty buffers with data and TIME_OUT if no more empty buffers
* are queued. If error is encountered, am empty buffer is queued to the output with
* V4L2_BUF_FLAG_LAST flag.
