node.js用ffmpeg切rtsp实时视频流为mp4,并且在网页上播放

用express.js框架,这部分太简单了,省略
npm或者yarn安装fluent-ffmpeg

路由部分代码:

router.rtspTrackingHandle = function (req, res) {
    logger.info('[tracking]: rtsp handle');
    let url = req.query.url || '';
    // let url = 'rtsp://admin:jeewey123@192.168.13.16:554/h264/ch1/main/av_stream';
    logger.info('[tracking]: rtsp url: ' + url);
    url = url.replace(/&/g, '%26'); // 大华摄像头的特殊符号转义
    logger.info('[tracking]: rtsp params: ', JSON.stringify(req.params));
    try {
        ffmpeg(url)
            .addInputOption('-rtsp_transport', 'tcp', '-buffer_size', '102400') // 这里可以添加一些 RTSP 优化的参数
            .on('start', function () {
                logger.info('[tracking]: Stream started.' + url);
            })
            .on('codecData', function () {
                logger.info('[tracking]: Stream codecData.' + url);
                // 摄像机在线处理
            })
            .on('error', function (err) {
                logger.error('[tracking]: An error occured: ' + `[${url}]::` + `[${err}]`);
            })
            .on('end', function () {
                logger.info('[tracking]: Stream end!' + url);
                // 摄像机断线的处理
            })
            .outputOptions(['-movflags isml+frag_keyframe'])
            .toFormat('mp4').noAudio().pipe(res, { end: true });
    } catch (error) {
        logger.error('[tracking]: ' + error.stack);
    }
};
