GStreamer Applications

GStreamer is a library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.

GStreamer is released under the LGPL. This section explains how to create and run the GStreamer applications on Wayland Window System. The applications can take advantage of codec, filter technology, and hardware processing of RZ Family MPUs by using Renesas GStreamer elements: omxh264dec, omxh265dec, omxh264enc, omxh265enc, vspmfilter, waylandsink.

Note:

• omxh265dec and omxh265enc are only for supported MPUs;
• The MPUs that support these elements are RZ/V2N, RZ/V2H, RZ/G3E MPUs.

Before you proceed to Application Samples section, please make sure to check Hello World README.

Application Samples

The following table shows multimedia applications in supported MPUs ranging from playing, recording, scaling, streaming audio/video, to displaying multiple videos on multiple monitors.

Application Name	Description
Audio Play	Play an MP3 audio file.
Video Play	Play an H.264 or H.265 video file.
Audio Encode	Encode audio data from F32LE raw format to Ogg/Vorbis format.
Video Encode	Encode video data from NV12 raw format to H.264 format.
Audio Record	Record raw data from USB microphone, then store it in Ogg container.
Video Record	Display and record raw video from USB/MIPI camera, then store it in MP4 container.
Audio Video Record	Record raw data from microphone and MIPI camera or USB webcam at the same time, then store them in MKV container.
Receive Streaming Video	Receive and display streaming video.
Send Streaming Video	Send streaming video.
Video Scale	Scale down an H.264 video, then store it in MP4 container.
Audio Player	A simple text-based MP3 audio player.
Video Player	A simple text-based MP4 video player.
Audio Video Play	Play H.264 video and MP3 audio file independently.
File Play	Play an MP4 file.
Multiple Displays 1	Display 1 H.264 or H.265 video simultaneously on HDMI monitor.
Multiple Displays 2	Display 2 H.264 or H.265 videos simultaneously on HDMI monitor.
Overlapped Display	Display 3 overlapping H.264 videos.

Note:

H.265 in the Application Samples is only for MPUs that support omxh265dec and omxh265enc.
