-f {H|V|I} implements “videoflip” image transforms: H = horizontal flip (right-left flip, or mirror image); V = vertical flip ; I = 180 degree rotation or inversion (which is the combination of H with V).
-r {R|L} 90 degree Right (clockwise) or Left (counter-clockwise) rotations; these are carried out after any -f transforms.
-vd decoder chooses the GStreamer pipeline’s h264 decoder, instead of letting decodebin pick it for you. Software decoding is done by avdec_h264; various hardware decoders include: vaapi264dec, nvdec, nvh264dec, v4l2h264dec (these require that the appropriate hardware is available). Using quotes “…” allows some parameters to be included with the decoder name.
--vc converter chooses the GStreamer pipeline’s videoconverter, instead of letting videoconvert choose what to do. When using video4linux hardware decoding by a GPU, v4l2convert will also use the GPU for video conversion. Using quotes “…” allows some parameters to be included with the converter name.

When using video4linux hardware decoding by a GPU,-vc v4l2convert will also use the GPU for video conversion. Using quotes “…” allows some parameters to be included with the converter name.
-vs videosink chooses the GStreamer videosink, instead of letting autovideosink pick it for you. Some videosink choices are: ximagesink, xvimagesink, vaapisink (for intel graphics), gtksink, glimagesink, waylandsink, osximagesink (for macOS), or fpsdisplaysink (which shows the streaming framerate in fps). Using quotes “…” allows some parameters to be included with the videosink name. For example, fullscreen mode is supported by the vaapisink plugin, and is obtained using -vs "vaapisink fullscreen=true"; this also works with waylandsink. The syntax of such options is specific to a given plugin, and some choices of videosink might not work on your system.
-vs 0 suppresses display of streamed video, but plays streamed audio. (The client’s screen is still mirrored at a reduced rate of 1 frame per second, but is not rendered or displayed.) This feature (which streams audio in AAC audio format) is now probably unneeded, as UxPlay can now stream superior-quality Apple Lossless audio without video in Airplay non-mirror mode.
-avdec forces use of software h264 decoding using Gstreamer element avdec_h264 (libav h264 decoder). This option should prevent autovideosink choosing a hardware-accelerated videosink plugin such as vaapisink.
