You can stream audio and video from your Mac to Chromecast and AirPlay devices, as well as to DLNA-enabled Smart TVs.

How to stream files:

1. Launch the application.

2. Click the application icon on the Menu bar to open the popover.

3. Add the file (s) to the playlist: click on the + button in the lower right corner of the popover. Select the files and/or folders with the files you want to stream to the device.

4. Select the device to which you want to stream files.

Note:

1. By default, the first available device is selected.

2. If there is no device in the list that you want to stream to, make sure that the device is turned on and connected to the same Wi-Fi network as your Mac, update the device list using the Refresh device list menu option. If the problem persists, see the Streaming FAQ.

5. Start the file streaming by double-clicking on it in the playlist or selecting the file and clicking the Start Streaming button.

Note: You can also start streaming by selecting Start Streaming from the context menu that opens by clicking on the ... (More) button on the corresponding row.

During file streaming, you can control playback:

1) pause / resume playback;

2) move to another position using the progress bar;

3) change the volume on the device (if the device supports it);

4) switch to other subtitles, add subtitles;

5) switch to another audio track, add an external audio track;

6) change the appearance of the subtitles (only on Chromecast devices) (see Preferences > Chromecast).

At the end of the file streaming, the next file from the playlist will automatically start streaming.

To end streaming, click the Stop Streaming button.

How to switch to other subtitles?

Click the ... (Other settings) button on the playback control block and select subtitles from the Subtitles context menu.

Note: JustStream automatically loads external subtitle files and audio tracks from the folder with the video file. But in the Mac App Store versions of JustStream subtitles and external audio tracks may not be loaded automatically because the app has restricted access to the file system. In the General tab in JustStream Preferences choose the root folder where most of your video files are saved. It helps JustStream get access to all files of this folder and automatically load external subtitle files and audio tracks (if any) during playback.

To add other subtitles, select the menu item Subtitles > Add from File...

JustStream uses 3 methods to stream subtitles:

1. External subtitles are stored in separate files and are streamed directly to the receiving device. It’s the most effective way to cast subtitles for a video since it does not require any processing from JustStream.

Note: Unfortunately, some devices don’t support external subtitles, e.g. Sony Bravia TVs.

2. Embedded subtitles are stored inside the video file/video container as streams. The same way video and audio streams are stored inside video files. If the file is 100% compatible with the receiving device, JustStream sends it as-is to the device.

Tip: Devices usually list all the embedded subtitles on the screen, so you can choose the proper ones by using the device’s remote control. You can also choose the preferred subtitle language.

Note: Support for displaying embedded subtitles depends on device model. The most popular video container with embedded subtitle support is Matroska (MKV). WD, Samsung, and Panasonic devices display embedded subtitles in MKV video files.

Some devices don’t support embedded subtitles. E.g. Chromecast devices can display only subtitles out-of-the-box delivered as a text file. JustStream has to extract such text-based subtitles from the video file before streaming.

Note: It may take a long time for large files or files on remote drives.

3. Burning subtitles are drawn (or superimposed) over the video frames in the video.

JustStream burns image-based subtitles (DVD VOBSUBs, Bluray PGS) into the video during on-the-fly transcoding. In order to do the same with text subtitles, you need to turn on the option “Burn subtitles into video” that’s found in Preferences > Subtitles. This can be used in situations where the receiving device doesn’t support both external and embedded subtitles.

How to switch to another audio track?

Click the ... (Other settings) button on the playback control unit and select an audio track from the Audio Track context menu.

To add an external audio track, select the menu item Audio Track > Use External Audio...

Tip: Some Smart TVs support internal audio tracks and you can switch to the desired audio track in the playback settings directly on the device.

Note: Switching to another audio track in JustStream will trigger the playback restart with on-the-fly transcoding of the media.
