Source: [https://docs.qualcomm.com/doc/80-88500-3/topic/28_Multimedia_use_cases.html](https://docs.qualcomm.com/doc/80-88500-3/topic/28_Multimedia_use_cases.html)

The different multimedia use cases supported on the QRB5165 device comprise single-stream and
      multi-stream playback, multiple-stream concurrency recordings, camera static and dynamic
      parameters, and overlay settings for video.

Create `/data/output` directory using `command:adb shell mkdir -p
        /data/output`.

This section provides information on executing common playback use cases from       `gst-launch`. The `qtic2vdec` GStreamer video decoder plug-in is     used for hardware-accelerated video decoding.
