How to stream mp4 videos from Django 3 to Vue.js

问题

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 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 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;
                });
            }
        }
    }

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?

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>
