GStreamer uses OpenMax-IL to control the VCU2 software.

See GStreamer Pipelines for more examples using gst-launch-1.0.

The following table shows the video/x-raw formats as used on a gst-launch-1.0 command line, and the related FourCC codes to properly describe pixel format. Note the GStreamer convention is to use lower case letters and - instead of _. However GStreamer element videotestsrc seems to use upper case and _ instead (so P010_10LE instead of p010-10le) while rawvideoparse does the opposite.

Element videotestsrc supports these formats in software. Use gst-inspect-1.0 videotestsrc to list them. If garbled characters are shown, add the --no-colors option or set GST_INSPECT_NO_COLORS to any value. An example:

gst-launch-1.0 videotestsrc num-buffers=2 ! "video/x-raw,width=1920,height=1080,format=P010_10LE" ! filesink location=out.yuv

Table 1 shows the properties that are supported by the omxh264enc (AVC) and/or omxh265enc (HEVC) GStreamer elements. Use gst-inspect-1.0 omxh264enc or gst-inspect-1.0 omxh265enc to list them. An example:

gst-launch-1.0 filesrc location=in.yuv ! rawvideoparse format=p212-12le width=1280 height=720 framerate=30/1 ! omxh265enc target-bitrate=6000 ! filesink location=out.265

See GStreamer Pipelines for more examples using gst-launch-1.0.

The following table shows the GStreamer and V4L2 related formats that are supported. For example, when a V4L2 capture component is connected to an encoder input, V4L2 formats need to match. The FourCC codes may differ between this two.
