vr renderer: Select a video renderer to use (rpi, gstreamer, or dummy)

a (hdmi|analog|off): Set audio output device As a side effect, playback will be choppy and audio-video sync will be noticably off. Low-latency mode reduces latency by effectively rendering audio and video frames as soon as they are received, ignoring the associated timestamps. f (horiz|vert|both): Specify image flipping. r (90|180|270): Specify image rotation in multiples of 90 degrees. b (on|auto|off): Show black background always, only during active connection, or never. n name: Specify the network name of the AirPlay server. Start the rpiplay executable and an AirPlay mirror target device will appear in the network.Īt the moment, these options are implemented:

ilclient and Broadcom's OpenMAX stack as present in /opt/vc in Raspbian.įor downloading the code, use these commands:.

libavahi-compat-libdnssd-dev (for the bonjour registration).

The following packages are required for building on Raspbian: RPiPlay might not be suitable for remote video playback, as it lacks a dedicated component for that: It seems like AirPlay on an AppleTV effectively runs a web server on the device and sends the URL to the AppleTV, thus avoiding the re-encoding of the video.įor rough details, refer to the (mostly obsolete) inofficial AirPlay specification.

Make sure no other demanding tasks are running (this is particularly important for audio on the Pi Zero)īy using OpenSSL for AES decryption, I was able to speed up the decryption of video packets from up to 0.2 seconds to up to 0.007 seconds for large packets (On the Pi Zero).

Make sure you don't use the -d debug log flag.

Make sure the DUMP flags are not active.

Compile with -O3 (cmake -DCMAKE_CXX_FLAGS='-O3' -DCMAKE_C_FLAGS='-O3'.

The Pi has no hardware acceleration for audio (AirPlay mirroring uses AAC), so the FDK-AAC decoder is used for that.īoth audio and video work fine on a Raspberry Pi 3B+ and a Raspberry Pi Zero, though playback is a bit smoother on the 3B+. The GPU is used for decoding the h264 video stream. Recent macOS versions also seem to be compatible.

Screen mirroring and audio works for iOS 9 or newer. The goal is to make it run smoothly even on a Raspberry Pi Zero. An open-source implementation of an AirPlay mirroring server for the Raspberry Pi.
