Six, Common Issues FAQ

We have compiled the most common issues encountered by users and provided specific solutions.

6.1 When casting, I can’t find my TV or device?

Please ensure that both your Mac and the target device are connected to the same Wi-Fi network. If your router has AP isolation enabled, temporarily disable it. Also, check if Miracast or DLNA features are enabled on your TV.

6.2 When playing videos, the picture is lagging or out of sync?

This is usually due to network bandwidth. Adjust the output quality to 720p, or close other applications that are using bandwidth. If you are using 5GHz Wi-Fi, stability will be better.

6.3 How do I load external subtitle files?

When playing a video, click the JustStream icon in the menu bar and select the “Subtitles” option. You can manually load subtitle files in .srt or .ass formats. Ensure that the subtitle file name matches the video file name to automatically load it.

6.4 Why does JustStream prompt for microphone permissions?

This is because the “System Audio Capture” feature for screen mirroring is enabled. Go to System Preferences > Security & Privacy > Privacy > Microphone and check JustStream to allow it.

6.5 Why does JustStream not have sound when casting to an Apple TV?

Check JustStream’s audio output settings. In the menu bar, ensure that “System Audio” is selected rather than “No Audio”. Also, confirm that the Apple TV’s volume is not muted.

6.6 Why can’t I play MKV format videos?

JustStream supports real-time transcoding, theoretically allowing playback of almost all formats. If playback fails, try dragging the video into the playlist, which will trigger transcoding automatically. If this still doesn’t work, the file encoding might be too special. Consider using tools like HandBrake to convert the file beforehand.

6.7 How can I reduce CPU usage?

Check if the “Real-time Transcoding” feature is enabled. If the target device supports the original format, you can disable transcoding in settings to reduce CPU load. Keeping the software up to date also optimizes performance.

6.8 How do I create and manage playlists?

Click the “+” button on the main interface to add files or folders to the playlist. You can drag and reorder items, or right-click to delete files. Playlists support loop and random play modes.

6.9 Does the activation version support updates?

This activation version has disabled the automatic update feature. Please do not click “Check for Updates” to avoid overwriting the activation file. For new features, please stay tuned for updates on our website.

Eight, Tips and Real-World Cases

Practice makes perfect. Below are a few real-life scenarios to help you maximize the value of JustStream.

8.1 Tip: Create a Home Theater Experience

Weekends are for family movie nights, but your laptop screen is too small. JustStream to the rescue! Open JustStream, select “Play Video File,” and drag in a downloaded 4K movie. The software will automatically transcode and mirror the video to your smart TV in the living room. With playlist functionality, you can play three movies in a row without any manual intervention.

8.2 Tip: A Business Presentation Tool

Presenting PPT to clients in a meeting room requires carrying adapters and HDMI cables. JustStream’s “Screen Mirroring” feature allows you to wirelessly project your Mac screen to a meeting TV. Enable “Cursor Control” to make your mouse movements visible, enhancing the professionalism of your presentation. According to Gartner, wireless mirroring can reduce meeting preparation time by 30%.

8.3 Tip: Online Education Scenario

During online teaching, teachers need to share their screen for presentations and demonstrations. JustStream’s “Screen Mirroring” feature allows you to project your Mac screen to a projector connected to a Chromecast. Use the “Pause/Resume” feature to pause the video when explaining key points, allowing students to take screenshots.

8.4 Tip: Game Streaming

Game enthusiasts want to project their Mac game screens onto a large TV. In JustStream settings, choose “Full HD” output and disable “Real-time Transcoding” to reduce latency. In a 5GHz Wi-Fi environment, latency can be controlled at around 50ms, which is sufficient for non-competitive games.

8.5 Tip: Audio Streaming

In the studio or kitchen, you want to play music from your Mac on a speaker system. Set JustStream to “Audio Only” mode, create an MP3 playlist, and wirelessly transmit it to a DLNA-compatible speaker. This is more stable and less intrusive than Bluetooth, and doesn’t occupy your phone’s channel.
