VLC for Fire TV

Amazon Fire TV stick 2016 with VLC

Stream wireless audio/video to TV from computer!
Plays virtually any valid file format!
Excellent quality video, audio, sync, even subtitles!

Several good network video streaming solutions are available (see Wireless HDTV Video) with the primary purpose of delivering content from the Internet, but streaming of local content (cell phone video, camera video, and other files) tends to be more difficult, often involving server software (e.g., Plex) on a computer, a problem for less technical users.

What tends to work better for most people is a TV-centric (client-centric) solution rather than a server-centric solution, where the TV is used to select and play content files. That's now possible with the advent of VLC Media Player for Amazon Fire TV and stick. VLC is an excellent free and open source app that can handle virtually any valid file format.

Installing VLC can be a bit tricky since VLC for Fire is not yet listed in the Amazon Appstore on the new 2016 Amazon Fire TV stick, which means you have to sideload VLC for Android (on which Fire TV is based):
  1. Download the latest ARMv7 of VLC for Android here.
    (Look for small APK package link below Play and Fire buttons.)
  2. Follow the instructions in How to Sideload Fire TV Apps.
    (If you have an Android phone, that method is probably the easiest.)
The second part of the process is to enable file sharing on a Windows and/or Mac computer, and share folders in which you will place files for streaming by VLC on your Fire TV.
To play files from your Fire TV:
  1. Start the VLC app.
  2. Select Browsing.
  3. Select Local Network.
  4. Select source network device (computer, network storage).
  5. Navigate to the audio or video file you want to play.
If you need help, try VLC for Android and Chrome OS Forum.

Tip: Fire TV is a great way to "cut the cord" (cable) with the excellent Sony PlayStation Vue service.

Wireless HDTV Video (update)

Microsoft Wireless Display Adapter
See Wireless HDTV Video (original)

The ability to beam video to a HDTV screen without wires has been promised for quite some time, but the product methods on offer (DLNA, Miracast, Wi-Fi Direct) have proved to be disappointing, complex and/or problematic. This update adds an additional option.

Microsoft Wireless Display Adapter

Promising easy setup and compatibility with both Android (4.2.1 and later) and Windows (8.1 and later), Microsoft Wireless Display Adapter comes close to hitting the mark. Setup is indeed easy (though not entirely free of problems, since more than one connect attempt may be needed), and audio sync and video quality are quite good (significantly better than Chromecast), but motion tends to be a bit jerky (1080p video tested over a short distance from Windows 8.1 with Intel i7 processor, Intel HD Graphics 5500, and Intel 802.11ac adapter), clearly not as good as HDMI cable connection. (Frames are probably being dropped to maintain streaming.)

Google Chromecast
Google Chromecast

With mighty Google behind it, inexpensive Chromecast would seem a sure winner. But right out of the box it can be problematic because it insists on network capabilities (access to Google Public DNS servers) that make it incompatible with some wireless routers. (See Chromecast Router Compatibility) Past that point things can look good at first blush, as when casting the screen of an Android mobile, or streaming YouTube video. But push it a bit harder and warts appear. Local video (from Android mobile or Chrome browser) is limited to 720p and relatively low bit rate by default, with poor quality, and even when pushed to its limits, quality is still only mediocre at best. So if you care about video quality, Chromecast is really just another Internet streaming option.

DLNA

Many "smart" HDTV sets claim DLNA Player support, which should make it possible to beam video to them over a network connection (wired or wireless), and the ubiquitous Windows Media Player includes DLNA Server support. (See Media Streaming with Windows 7) But try to make it work and you're very likely to run into compatibility problems, since many HDTV sets are very fussy about what video formats they will (and will not) play, and Windows Media Player does not support transcoding between formats. (While there DLNA servers that can transcode on the fly, they can be difficult to set up, and the resulting quality is often mediocre. Your best bet is to use Handbrake to transcode to MPEG-4 in advance.) But even when it works, video quality is noticeably inferior to a wired HDMI connection.

Bottom line: Beaming of HDTV video without wires remains a work in progress.
  • For best quality use a wired HDMI connection.
  • If you must have wireless, Microsoft Wireless Display Adapter is the best bet.

HDTV Antenna

ClearStream 2V
With increased online HD quality video streaming from the likes of Amazon, Netflix, Hulu, and YouTube, and with cable TV bills climbing ever higher, it's becoming more attractive and practical to cut the cable, especially if you can get free digital TV signals (HD quality) over the air.

You have the legal right to install your own antenna for over the air reception, and you can check to see what channels you may be able to receive at TV Fool.

Some of the best antenna options for relatively short range reception, as tested in San Francisco (TV Fool report).

Antennas Direct ClearStream 2V

Easy to assemble. High quality construction. Solidly pulled in all green and yellow stations reported by TVFool, both VHF Hi and UHF.

If you need or want the best in this range class, this is the antenna to buy.

If you need longer range reception, Antennas Direct also has more powerful options, as well as a good indoor option, Micron R, which may be available at a bargain price refurbished.

RCA ANT751

RCA ANT751
Relatively easy to assemble, except a bolt was missing, purchased replacement from local hardware store. Also purchased cable zip ties to secure coax to mast and boom. One element was loose enough to wobble freely due to poor riveting, had to insert shims to stabilize.

Pulled in all green stations reported by TVFool, both VHF Hi and UHF, but not solid on yellow.

Good value.

Summary

ClearStream 2V definitely more sensitive than ANT751, in addition to better construction quality, clear on yellow UHF channels that break up on ANT751, also picked up a very weak (unwatchable) VHF station not found by ANT751.

However, ANT751 may be sufficiently good for many purposes (if yellow stations are not of interest), and is much less expensive ($50 vs $100).
