[英]React native camera not recording video
我想使用 react native video 實現視頻錄制功能,但是開始錄制功能沒有給出任何響應,我什至安慰它是否被調用了,實際上不是,我無法弄清楚我做錯了什么。
下面是我寫的確切代碼
import React from 'react';
import {
View,
Text,
TouchableOpacity,
StyleSheet,
ActivityIndicator,
} from 'react-native';
import {RNCamera} from 'react-native-camera';
export default class Shoot extends React.Component {
constructor(props) {
super(props);
this.state = {
recording: false,
processing: true,
};
}
async startRecording() {
this.setState({recording: true});
// default to mp4 for android as codec is not set
const {uri, codec = 'mp4'} = await this.camera.recordAsync();
}
stopRecording = () => {
this.camera.stopRecording();
};
render() {
const {recording, processing} = this.state;
let button = (
<TouchableOpacity
onPress={this.startRecording.bind(this)}
style={styles.capture}>
{console.log('aaa')}
<Text style={{fontSize: 14}}> RECORD </Text>
</TouchableOpacity>
);
if (recording) {
button = (
<TouchableOpacity
onPress={this.stopRecording.bind(this)}
style={styles.capture}>
<Text style={{fontSize: 14}}> STOP </Text>
</TouchableOpacity>
);
}
if (processing) {
button = (
<View style={styles.capture}>
<ActivityIndicator animating size={18} />
</View>
);
}
return (
<View style={styles.container}>
<RNCamera
ref={(ref) => {
this.camera = ref;
}}
style={styles.preview}
type={RNCamera.Constants.Type.back}
flashMode={RNCamera.Constants.FlashMode.on}
permissionDialogTitle={'Permission to use camera'}
permissionDialogMessage={
'We need your permission to use your camera phone'
}
/>
<View style={{flex: 0, flexDirection: 'row', justifyContent: 'center'}}>
{button}
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'column',
backgroundColor: 'black',
},
preview: {
flex: 1,
justifyContent: 'flex-end',
alignItems: 'center',
},
capture: {
flex: 0,
backgroundColor: '#e75480',
borderRadius: 40,
width: 80,
height: 80,
paddingHorizontal: 20,
alignSelf: 'center',
margin: 20,
},
});
所以在這里,按鈕可觸摸性 onpress 即 startRecording 根本沒有被調用。 任何幫助都會很棒,謝謝
我仍然無法弄清楚上面的代碼出了什么問題,但是使用 react-native-beautiful-video-recorder 作為包,我終於找到了該應用程序按照我的要求運行。 如果有人遇到同樣的問題,最好使用 react-native-beautiful-video-recorder。
嘗試使用帶箭頭功能的 onPress
<TouchableOpacity
onPress={() => this.startRecording()}
style={styles.capture}>
{console.log('aaa')}
<Text style={{fontSize: 14}}> RECORD </Text>
</TouchableOpacity>
並綁定這個
constructor(props) {
super(props);
this.state = {
recording: false,
processing: true,
};
this.startRecording = this.startRecording.bind(this)
}
render() {
const {recording, processing} = this.state;
let button;
if (recording) {
button = (
<TouchableOpacity
onPress={this.stopRecording.bind(this)}
style={styles.capture}>
<Text style={{fontSize: 14}}> STOP </Text>
</TouchableOpacity>
);
}
else if (processing) {
button = (
<View style={styles.capture}>
<ActivityIndicator animating size={18} />
</View>
);
}
else {
button = (
<TouchableOpacity
onPress={this.startRecording.bind(this)}
style={styles.capture}>
{console.log('aaa')}
<Text style={{fontSize: 14}}> RECORD </Text>
</TouchableOpacity>
);
您正在處理的問題比您想象的要簡單得多
你的初始狀態是這個
this.state = {
recording: false,
processing: true,
};
所以如果處理和錄制為 false 則按鈕呈現,初始按鈕啟動視頻,因此您的初始狀態必須是這個
this.state = {
recording: false,
processing: false,
};
