尝试使用Shahen的反应原生视频处理:
以下是代码:
compressVideo(source) {
const options = {
width: 800,
height: 800,
bitrateMultiplier: 3,
saveToCameraRoll: true,
saveWithCurrentDate: true,
removeAudio: true
};
ProcessingManager.compress(source, options)
.then(data => {
console.log(data);
this.setState({ base64String: data });
})
.catch(console.warn);
}
但它在Android设备中出错。

此问题的任何解决方案或在上传前压缩视频的任何其他方法。

使用rn-fetch-blob for android先转换路径,因为你得到的URI在android的情况下是临时的,在目录中找不到,
const res = await RNFetchBlob.fs.stat(SOURCE_URI);
src = "file://" + res.path;
ProcessingManager.compress(src, options)
.then(data => {
console.log(data);
this.setState({ base64String: data });
})
.catch(console.warn);
这将解决路径问题。

试试下面的代码,在 react-native 中成功压缩视频。它将 81MB 压缩成近 43MB。
import { Platform } from 'react-native';
import {RNFFmpeg} from "react-native-ffmpeg"
import RNFS from 'react-native-fs';
function processVideo(videoUrl, callback) {
const finalVideo = `${RNFS.CachesDirectoryPath}/audioVideoFinal.mp4`;
cacheResourcePath(videoUrl).then((rVideoUrl) => {
const str_cmd = `-y -i ${rVideoUrl} -vcodec mpeg4 -acodec aac -qscale:v 3 -q:a 4 ${finalVideo}`;
RNFFmpeg.execute(
str_cmd,
).then((result) => {
if (result === 0) {
RNFS.unlink(rVideoUrl);
callback({
videoPath:
Platform.OS === 'android' ? 'file://' + finalVideo : finalVideo,
});
}
});
});
};
async function cacheResourcePath(sourcePath) {
const uriComponents = sourcePath.split('/');
const fileNameAndExtension = uriComponents[uriComponents.length - 1].replaceAll(' ','');
const destPath = `${RNFS.CachesDirectoryPath}/${fileNameAndExtension}`;
await RNFS.copyFile(sourcePath, destPath);
return destPath;
}
