Six, Commonly Asked Questions FAQ

We have collected the most frequently encountered issues by users when using JustStream and provided detailed answers.

Q1: JustStream cannot find my TV or Chromecast?

A: First, ensure that your Mac and the target device are connected to the same Wi-Fi network. Next, check your Mac’s firewall settings to make sure they are not blocking JustStream’s network access. Finally, try restarting the router and the target device; sometimes a simple network reset can solve the problem.

Q2: During screen sharing, the picture is lagging or out of sync with the audio?

A: This is usually related to the network environment. Try adjusting the output quality to “HD (720p)” to reduce bandwidth usage. Also, close other applications on your Mac that are using network resources, such as online videos or large download tasks. If using a wireless network, try to be closer to the router.

Q3: Why can’t I play certain MKV format videos?

A: Although JustStream supports a wide range of formats, some specially encoded MKV files may require real-time transcoding. Ensure that your Mac’s performance is sufficient, especially for older models with Intel chips. You can try selecting the “real-time transcoding” option in the software settings.

Q4: Subtitle files display garbled text or cannot be loaded?

A: Ensure that the subtitle files (.srt, .ass) are in the same folder as the video file and have the same file names. If still garbled, try saving the subtitle file as UTF-8 encoding using a text editor. In the subtitle settings of JustStream, you can also adjust the font and encoding type.

Q5: Screen mirroring function cannot capture mouse click effects?

A: In the JustStream screen mirroring settings, make sure the “Mouse Cursor and Click Capture” feature is enabled. This feature may be disabled by default and needs to be manually activated to see mouse operation trails on the TV.

Q6: JustStream does not work properly on macOS Sequoia?

A: Version 2.10 has made compatibility improvements for macOS Sequoia. If still encountering issues, check “System Settings” -> “Privacy & Security” -> “Local Network,” ensuring that JustStream’s switch is turned on. This is a necessary permission for the new system.

Q7: How to create and manage playlists?

A: In the JustStream main interface, click on the “Playlists” tab. You can add local files or folders using the “+” button. Drag files to reorder them. After creating, choose the playlist and click “Play” to achieve continuous playback.
