Imira

Imira mirrors the phone screen and audio to a Miracast sink - a TV or an HDMI dongle - over Wi-Fi Direct. No app on the TV, no cables, no network: the phone talks to the sink directly. As far as I know this is the first working Wi-Fi Display source for Sailfish OS. It's still very experimental.

FOR SMOOTH CASTING: MIND YOUR WI-FI
The phone has one radio. If it is connected to your Wi-Fi network on a different channel than the cast, it has to hop back and forth - heard as dropouts, seen as a stuttering or black picture.
- Best: no Wi-Fi connection while casting (Wi-Fi on, but not connected). The cast has the radio to itself.
- Fine: a 2.4 GHz network (this is what i'm using).
- Avoid: 5 GHz networks while casting, or disconnect.

WHAT IS STABLE, WHAT IS NOT
- Mirroring your screen and audio to a TV/dongle works on the tested hardware.
- The convergence direction (the TV as a separate desktop with its own apps) is early and experimental.
- Tested on the Xperia 10 III (Sailfish OS 5.0.0.62) and the Jolla Phone 2026 (Sailfish OS 5.2.0.17), against a Microsoft Wireless Display Adapter V2 and an LG webOS TV. Other phones and receivers (projectors, Samsung TVs, ...) are new territory.
- Your receiver does not work? About -> Diagnostics: switch on the detailed log, try a cast, create a report. It is anonymized, saved in Documents and can be copied straight into the forum or an issue.
- Known rough edge: playing a video in the Gallery WHILE casting can crash the Gallery's playback (hardware encoder and decoder share the video core).

PLEASE READ - WHAT THE PACKAGE INSTALLS SYSTEM-WIDE
Miracast on Sailfish is not possible with the stock system, so this package is invasive by necessity:
- a root systemd service (imira.service) for Wi-Fi Direct, the WFD/RTSP handshake, screen capture and H.264/RTP streaming. It is NOT started at boot: the app starts it when opened (a polkit rule allows exactly this one unit), and it stops by itself when the app is closed;
- a bundled, P2P-capable wpa_supplicant under /usr/libexec/imira/ (the stock one has Wi-Fi Direct compiled out) - used only while scanning or casting;
- a PulseAudio policy file so the daemon can capture the audio without touching the microphone;
- the app runs without the Sailfish sandbox, because it exchanges control/status files with the service.
Nothing leaves your network - the phone streams directly to the receiver. Removing the app removes all of it.

STATUS AND RESPONSIBLE USE
Work in progress, shared as is, no warranty (GPLv3). This touches Wi-Fi and system audio deeply and runs a root service; install it because you want to experiment with Miracast on Sailfish, not because you need a polished tool. Feedback with your phone and receiver model is welcome - ideally with a diagnostics report.
