● Dimming: computer screen can be dimmed while playing (e.g. a movie in a dark room)
● Time shift: if needed, video and audio can be offset +/- 1000 ms in 25 ms steps

Audio driver
● Dedicated audio driver that allows to capture & transmit audio regardless of what source is playing
● Due to App Store rules (no app can have attached any driver in the store), the driver needs to be installed manually from:

(*) - The app needs a Mac model 2011 or higher.

WEB VIDEO STREAMER . (the mode requires High Sierra or Mojave)
● Emulates iOS web browser and streams videos on TV using TV built-in DLNA technology
● No other equipment necessary - only Mac, Wi-Fi & TV
● Compared to screen mirroring apps, no need to install any audio driver
● Solid >30MB A/V buffer ensures stream stability
● Significantly saves battery as the app re-streams video without H.264 re-encoding
● You can work on Mac and stream video on the background simultaneously

Supported media types
● Videos that can be played in iOS Safari (w/exception of FairPlay)
● Audio podcasts (w/exception of audio live streams)

Supported containers
● MP4
● HLS:
-- combined audio/video streams
-- separated audio/video streams
-- video only streams
-- fMp4 streams
-- live streams for all of the above-listed combinations
-- streams encrypted with AES-128 & AES-sample for all of the above-listed combinations
● MP3

Non-supported Types
● FairPlay (Apple proprietary tech enforcing DRM)
● (Live) audio-only HLS streams & MP3 live streams (no DLNA support)
● Subtitles (no DLNA support)
● Videos whose authors explicitly forbade (in html code) to play from their web pages via AirPlay

Web browser
● macOS built-in Safari engine ensures up-to-date security patches regardless of this app updates
● User-agent exception editor for domains you won't play video from (for easier browsing)
● Video quality exception editor for e.g. slow-loading webs
● Local-video manager: mute & auto-stopping when streaming

● Provides two modes: MP4 & Direct
-- MPEG streaming mode (mp4, mov) with locally seekable preview;
-- Direct streaming mode plays all TV-supported formats (typically AVI, 3GPP, DIVX,FLV,MKV,..)

● Samsung: All 2013+ models
● LG:
-- Web video streamer & file streamer: All 2012+ models
-- Mirroring: 2012-2016 LG models
(LG introduced in 2017 models a proprietary streaming mgr that is not suitable for short-lag transmissions; mirror will work but lag will be longer).

● The app is free for sessions up to 3 minutes; unlimited transfers as a one-off in-app purchase.

● Due to DLNA TV buffer, there is typically 1-3 sec lag between what is shown on monitor and TV , i.e. the app is not primarily intended for real-time activities such as gaming.
● By default, you can cast your screen video (useful e.g. for showing photos, giving presentations, browsing web, etc). If you want to transfer also audio together with video, you will need to install audio driver (instructions provided in the app, link above).
● You can't mirror DRM protected content.


Version 3.0.3

+ fix for local video preview

Kommt wohl auf den TV an

Das Programm selbst hat sich problemlos zu einem LG älteren Baujahrs verbunden und wenn man auf Play drückt, sah man den Screen. Leider ist es mir aber nicht gelungen die fps-Rate so weit zu drücken, das man hätte Sky Tennis oder Fußball hätte schauen können. Ich gehe aber davon aus, das das am TV liegt. Zudem war das WLAN für SkyGo so lala. Ansonsten mag ich die Idee und deren Umsetzung des Programms.

Super App!

Läuft am LG TV einwandfrei, 4K-Inhalte lassen sich problemlos übertragen. Die App ist schlicht aufgebaut, dafür aber sehr übersichtlich und damit einfach zu bedienen! Übringens funktioniert die App auch bestens mit der XBOX ONE.

Ich habe bislang Beamer benutzt um über Apple TV HD-Inhalte zu streamen. Mit Smartcast funktioniert das auch ohne Apple TV. Die App ist nicht schön und hat nicht viele Optionen (oder ich habe sie nicht gefunden (z.B. für Untertitel usw.) aber sie funktioniert.
