FAQ

Which browser gives the best experience for this WebRTC/RTSP player?

We recommend Chrome or Microsoft Edge (Chromium-based) to ensure all features work correctly.

Can local file playback history be remembered?

Due to browser security restrictions, playback history for local files (Blob) cannot be preserved after refreshing the page.

How to quickly add subtitles or chapters?

Simply select subtitle files (.srt/.vtt/.json) or chapter files from your folder and drag them into the player area for automatic loading.

How to use subtitle search and jump to results?

Click the "Subtitle" button on the player control bar, select "Subtitle Search", enter keywords, and all matching lines with timestamps will appear below. Click any result to instantly jump to that position.

How to extract the audio of specific subtitle segments from a video?

First use 'Subtitle Search' to locate the target content, click the 📍 locate button in the results to jump to the full list, then use the 'Segment Selection' feature to mark the target range (or consecutively click the loop buttons of two subtitles to form a cross-line segment), and finally click the 'Record' button to export only that segment's audio.

Can HLS embedded subtitles be searched and translated?

The challenge with HLS embedded subtitles is that they are scattered across individual ts segments — browsers cannot fetch them as a whole natively. ZWPlayer uses a proprietary ts-segment pre-download technology to fetch and parse upcoming segments in the background, assembling the embedded subtitles into a complete indexed structure, which then supports full-text search and API translation just like external subtitles.

How do I share the current video? Does sharing leak my privacy?

Click the Share button in the main control bar or in the History/Favorites list — a QR code and a full link will appear. Anyone can play the video by opening the link (or scanning the code with their phone). The QR code is generated entirely in your browser; the video URL is never uploaded to any server. Note that local files (Blob) cannot be shared, and the video URL in the share link is in plain text — anyone who gets the link can play it.

What does the "Segment Selection" feature do?

This feature is designed for online videos.

After selecting a segment, the player will loop that part.
Click the "Record" button to save only that segment.

How to record or extract audio only in the browser?

Click the "Record" button and choose "Audio Only". You can also preset "Extract Audio Only" in Settings → Recording Settings for future recordings.

Audio volume is maxed out but still too quiet — what to do?

Go to Settings → Audio Enhancement and enable Volume Boost — up to 4× amplification available using HTML5 Web Audio API.

How to view keyboard shortcuts?

Right-click on the player area and select "Shortcut Guide" to view the full list of hotkeys.

What are the quick playback and positioning operations?

1) Click "Speed" to select playback speed; 2) Tap left/right arrow to seek 5s; 3) Long press right arrow for fast forward; 4) Shift+2 for 2x speed; 5) Press 0 to go to beginning.
