Every answer in full.
Muxivo plays the video files other players struggle with — MKV, AVI, TS and more — and sends them to your TV over AirPlay with picture as well as sound. It runs on the Mac, from the App Store. iPhone and iPad versions are coming soon, and an app that runs on the Apple TV itself is in development — see the roadmap.

This is the problem Muxivo was built to solve, so if you are seeing it in Muxivo, something is wrong — tell us. If you are seeing it in another app, it is expected: players that draw video frames themselves cannot hand video to AirPlay, only audio.
Give it a few seconds — device discovery is not instant, and Muxivo shows "searching for devices" until one is found. If it stays empty:
Some televisions accept a narrower range of video than they advertise — unusual resolutions, high frame rates, or very high bitrates. When one refuses a stream it does not announce it: Muxivo shows the TV as connected and the picture never arrives. Waiting will not change it. Stop the cast and start it again, and if the same film fails twice, try a different one — that tells you whether the problem is the television or that particular file.
It helps enormously to tell us the make and model of the TV along with the file's format, since receiver behaviour varies a lot between brands.
Not yet — iPhone and iPad versions are coming soon. Until then Muxivo is a Mac app.
From the Mac it works the way you'd expect: the video is converted on the Mac and the television fetches it from there. Both need to be on the same Wi-Fi network.
Try resetting the paired devices in your TV's AirPlay settings, then connect again. Televisions remember Macs by an identity that can go stale — for instance after you migrate to a new computer.
Muxivo plays MKV, MP4, MOV, AVI, TS/M2TS and VOB. If a file in one of those formats won't open, please send us the exact name and, if you know it, the video and audio formats inside — that is usually enough to identify the problem.
Some soundtracks cannot be decoded without licensed decoders that are not available to third-party apps — Dolby TrueHD and the lossless layer of DTS-HD Master Audio are the common cases. Where the file includes a second, ordinary soundtrack, Muxivo switches to it automatically and tells you it has done so in the Audio menu. Where it doesn't, there is unfortunately nothing we can do.
Text subtitles appear in the Subtitles menu — both SRT files sitting beside the video and text tracks stored inside it. They are drawn with the words and their position on screen; the colours, fonts and effects that heavily styled subtitles carry are not drawn today.
Subtitles that are pictures rather than text have to be drawn into the video itself, so choosing one starts a conversion rather than appearing instantly. That works for Blu-ray subtitle tracks in an MKV. Other picture subtitles are listed in the menu and will not appear — that one is ours to fix.
Muxivo indexes a file before playing it, and a very large file — 30 GB and up — can take a few seconds. Most files start in about a second. A film that isn't an ordinary widescreen shape — scope-ratio cinema, or older standard-definition material — takes a couple of seconds longer.
The more of this you can include, the faster it gets fixed:
Running Muxivo from Terminal with MUXIVO_DEBUG=1 prints what the player decided and why. Copying that in is the single most useful thing you can send.
