如何将mp4视频从Django 3流传输到Vue.js [英] How to stream mp4 videos from Django 3 to Vue.js

问题描述

我正在尝试将Django的mp4视频流加载到Vue.js.我在此处遵循了解决方案，并通过我的axios API得到了一个字节字符串，并将其连接到data:video/mp4;base64,，然后将其绑定到视频标签的:src属性，但视频未显示.这是将视频从Django 3流传输到Vue.js的正确方法吗?我在做什么错了?

I'm trying to load a mp4 video stream from Django to Vue.js. I followed the solution here and got a byte string via my axios API which I concatenated to data:video/mp4;base64,, and then binded it to the video tag's :src property, but the video is not displaying. Is this the correct way to stream videos from Django 3 to Vue.js? What am I doing wrong?

Api.js代码段:

Api.js code snippet:

import axios from 'axios'

export default () => {
    return axios.create({
        baseURL: `http://127.0.0.1:8000/`,
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json',
        }
    })
}

Video.vue组件代码段:

Video.vue component code snippet:

    methods: {
        async stream() {
            return await VideoService.stream(this.video)
            .then(function(data) {
                return data.data;
            });
        }
    },
    props: ['data'],
    watch: {
        data: {
            deep: true,
            immediate: true,
            handler(curr, prev) {
                this.video = curr;
                this.stream().then(data => {
                    data = Buffer.from(data, 'binary').toString('base64');
                    this.video = 'data:video/mp4;base64,'+data;
                });
            }
        }
    }

正如该答案的注释中所建议的，我还将src设置为Django api端点，例如src="/video/test.mp4，但是我可以在终端中看到它没有到达该Django路由.如何获得链接的解决方案以与Vue.js一起使用?

As suggested in the comments of that answer, I also set src to the Django api endpoint e.g. src="/video/test.mp4, but I can see in my terminal that it's not reaching that Django route. How do I get the linked solution to work with Vue.js?

推荐答案

如果您对视频使用相同的组件，则将视频流式传输到Vue.js所需的最终解决方案是使用v-html设置src标签.这样您就可以动态设置src.创建组件后，直接执行src="http://localhost:8000/v/video.mp4"将不起作用.因此，除了Kevin的代码外，只需在视频组件中执行以下操作即可:

The final solution needed to stream videos to Vue.js if you're using the same component for videos is to set the src tag using v-html so that you can set src dynamically. Directly doing src="http://localhost:8000/v/video.mp4" won't work once the component is created. So in addition to Kevin's code, just do the following in the video component:

<template>
    <div>
        <video v-html="src" autoplay="" controls="" loop="" muted="" frameborder="0">
            Your browser does not support HTML videos.
        </video>
    </div>
</template>

<script>
export default {
    data() {
        return {
            src: ''
        }
    },
    props: ['data'],
    watch: {
        data: {
            deep: true,
            immediate: true,
            handler(curr, prev) {
                this.src = '<source src="http://localhost:8000/v/"'+curr+' type="video/mp4">'
            }
        }
    }
}
</script>

<style scoped>
</style>
