react-native-txc-player

React Native Fabric view that wraps Tencent Cloud LiteAV Player Premium (TXLiteAVSDK_Player_Premium) for iOS and Android. It renders the underlying TXVodPlayer directly (no bundled SuperPlayer UI) and provides a minimal API for supplying a source, listening to playback events, and issuing commands from JS.

The player automatically releases its native resources when the React component unmounts to avoid GC pressure on Android.

Installation

yarn add react-native-txc-player
# or
npm install react-native-txc-player

iOS

cd ios && pod install

The iOS target links the TXLiteAVSDK_Player_Premium CocoaPod and requires that you set a licence before playback (see Licence below).

Android

No manual steps are required. The library depends on com.tencent.liteav:LiteAVSDK_Player_Premium:latest.release, which uses LiteAV's automatic AAR loader. Make sure your Gradle repositories include either Tencent's public mirror or the official LiteAV artifact host (https://liteavsdk-1252463788.cos.ap-guangzhou.myqcloud.com/release) so the loader can fetch the Premium package.

Licence

Before mounting the player, initialise the LiteAV SDK licence exactly once in your app lifecycle:

import { setTXCLicense } from 'react-native-txc-player';

setTXCLicense('https://your-license-url', 'your-license-key');

Usage

1. Initialise the LiteAV licence

Call setTXCLicense once when your application starts. The SDK requires a licence URL/key pair before any playback can begin.

import { setTXCLicense } from 'react-native-txc-player';

setTXCLicense('https://your-license-url', 'your-license-key');

2. Render a player view

The snippet below shows how to wire up a basic player with tap-to-pause, progress updates, and a couple of imperative commands.

import { useCallback, useMemo, useRef, useState } from 'react';
import { Alert, Pressable, StyleSheet, Text, View } from 'react-native';
import {
  Commands,
  TxcPlayerView,
  type ChangeEvent,
  type ProgressEvent,
  type TxcPlayerViewRef,
} from 'react-native-txc-player';

const SOURCE = {
  appId: 'your-app-id',
  fileId: 'your-file-id',
  psign: 'your-psign',
};

type PlayerStatus = 'buffering' | 'playing' | 'paused' | 'ended' | 'error';

export default function PlayerCard() {
  const playerRef = useRef<TxcPlayerViewRef>(null);
  const [status, setStatus] = useState<PlayerStatus>('buffering');
  const [paused, setPaused] = useState(false);
  const [position, setPosition] = useState(0);
  const [duration, setDuration] = useState(0);
  const [message, setMessage] = useState<string | null>(null);

  const formattedProgress = useMemo(() => {
    const total = duration > 0 ? duration.toFixed(1) : '??';
    return `${position.toFixed(1)}s / ${total}s`;
  }, [duration, position]);

  const handlePlayerEvent = useCallback((event: { nativeEvent: ChangeEvent }) => {
    const evt = event.nativeEvent;
    setMessage(evt.message ?? null);

    if (typeof evt.duration === 'number') {
      setDuration(evt.duration);
    }

    switch (evt.type) {
      case 'begin':
      case 'firstFrame':
      case 'loadingEnd':
        setStatus(paused ? 'paused' : 'playing');
        break;
      case 'end':
        setStatus('ended');
        setPaused(true);
        break;
      case 'error':
        setStatus('error');
        setPaused(true);
        Alert.alert('Playback error', `code=${evt.code}, message=${evt.message}`);
        break;
      default:
        break;
    }
  }, [paused]);

  const handleProgress = useCallback((event: { nativeEvent: ProgressEvent }) => {
    if (typeof event.nativeEvent.position === 'number') {
      setPosition(event.nativeEvent.position);
    }
  }, []);

  const togglePlayback = useCallback(() => {
    setPaused((current) => {
      const next = !current;
      setStatus(next ? 'paused' : 'playing');
      return next;
    });
  }, []);

  const restart = useCallback(() => {
    if (playerRef.current) {
      Commands.seek(playerRef.current, 0);
    }
  }, []);

  return (
    <View style={styles.container}>
      <Pressable style={styles.player} onPress={togglePlayback}>
        <TxcPlayerView
          ref={playerRef}
          paused={paused}
          source={SOURCE}
          onPlayerEvent={handlePlayerEvent}
          onProgress={handleProgress}
          style={StyleSheet.absoluteFill}
        />
      </Pressable>

      <Text style={styles.metaText}>{`Status: ${status}`}</Text>
      <Text style={styles.metaText}>{`Progress: ${formattedProgress}`}</Text>
      {message && <Text style={styles.metaText}>{`Message: ${message}`}</Text>}

      <Pressable onPress={restart} style={styles.button}>
        <Text style={styles.buttonLabel}>Seek to 0s</Text>
      </Pressable>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    gap: 12,
    padding: 16,
    borderRadius: 12,
    backgroundColor: '#101010',
  },
  player: {
    aspectRatio: 16 / 9,
    borderRadius: 10,
    overflow: 'hidden',
    backgroundColor: '#000',
  },
  metaText: {
    color: '#fff',
  },
  button: {
    alignSelf: 'flex-start',
    paddingHorizontal: 12,
    paddingVertical: 8,
    borderRadius: 6,
    backgroundColor: 'rgba(255,255,255,0.15)',
  },
  buttonLabel: {
    color: '#fff',
    fontWeight: '600',
  },
});

Props

| Prop | Type | Description | | --- | --- | --- | | paused | boolean (default false) | When true the player is paused; set to false to play/resume. | | source | { url?: string; appId?: string; fileId?: string; psign?: string } | Either pass a direct URL or a VOD fileId with the corresponding appId/psign. | | playbackRate | number | Playback speed multiplier (default 1). Applies equally on iOS/Android via TXVodPlayer.setRate. | | onPlayerEvent | (event) => void | Receives events such as begin, firstFrame, progress, end, loadingEnd, error. The payload also contains code/message when available. | | onProgress | (event) => void | Fires with { position } updates for the current playback position (in seconds). |

Commands

import { Commands } from 'react-native-txc-player';

Commands.pause(ref);
Commands.resume(ref);
Commands.reset(ref); // stops and resets the underlying native player
Commands.seek(ref, 42); // jump to 42 seconds (best-effort)
Commands.destroy(ref); // releases the native player instance and clears its source

预下载（Pre-download）

通过 LiteAV 的 TXVodPreloadManager 可以把即将播放的视频数据提前缓存到本地，降低首帧等待。库内提供跨平台的辅助方法，参考 官方文档。

import {
  startPreDownload,
  stopPreDownload,
  addPreDownloadListener,
  type PreDownloadEvent,
} from 'react-native-txc-player';

// 1. 启动预下载（支持 URL 或 fileId）
const taskId = await startPreDownload({
  url: 'https://example.com/video.m3u8',
  // 或者:
  // appId: '123456789',
  // fileId: '528589080xxxxxxx',
  // psign: 'xxx', // 可选
  preloadSizeMB: 10,
  preferredResolution: 1920 * 1080,
});

// 2. 监听进度（start / complete / error）
const sub = addPreDownloadListener((event: PreDownloadEvent) => {
  console.log('pre-download', event);
});

// 3. 取消任务
stopPreDownload(taskId);

// 4. 组件卸载时清理监听
sub.remove();

Auto-destroy helpers

For list or carousel UIs where you want to automatically release the previously playing instance when a new cell becomes active, use the useTxcPlayerAutoDestroy hook. It destroys the native player when the component unmounts and (by default) ensures only one player stays active at a time.

import { useRef, useMemo } from 'react';
import {
  TxcPlayerView,
  type TxcPlayerViewRef,
  useTxcPlayerAutoDestroy,
} from 'react-native-txc-player';

function FeedPlayer({ itemId, activeId, source }: Props) {
  const ref = useRef<TxcPlayerViewRef>(null);
  const isActive = useMemo(() => activeId === itemId, [activeId, itemId]);

  useTxcPlayerAutoDestroy(ref, { active: isActive, destroyOnDeactivate: true, exclusive: true });

  return (
    <TxcPlayerView
      ref={ref}
      paused={!isActive}
      source={source}
    />
  );
}

Events

Event payload example:

{
  "type": "error",
  "code": -2301,
  "message": "Network disconnected"
}

type values currently emitted: begin, firstFrame, loadingEnd, end, error, and progress.

• progress is delivered roughly every 250 ms with the current position, full duration, and buffered amount (buffered) in seconds. Use it to drive custom progress UIs without polling native state.

Android resource management

The Android view registers as a LifecycleEventListener and automatically stops playback, destroys the TXCloudVideoView, and releases the TXVodPlayer when the React view unmounts or the host Activity is destroyed. This mirrors the recommendations in Tencent's documentation to prevent leaked native surfaces and GC pressure.

Example

The repository ships with an example app (located in the example workspace) that demonstrates licence initialisation and tap-to-pause/resume behaviour.

yarn install
yarn example ios   # or `yarn example android`
