本文介绍了我的 HTML5 视频标签没有播放视频的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在尝试播放用户使用 <video 标签上传的视频,但由于某种原因它似乎没有加载到 DOM.这是我的代码:

函数视频({uploadedFiles}){如果(上传的文件){console.log(上传文件[0])返回(<div><h3>视频</h3><视频控件宽度="400"><source src={uploadedFiles[0]} type="video/mp4"/>您的浏览器不支持 HTML5 视频.</视频>

)} else return(<div><h2>没有上传视频</h2></div>)}

当我做 console.log(uploadedFiles[0]) 我得到 y2mate.com - after_effect_countdown_10_seconds_iDO9J_3OVJ0_1080p.mp4 应该在视频标签内作为 源代码.我的文档类型是 html.我哪里出错了?

解决方案

试试下面显示的方法,看看效果是否更好.如果成功,则将类似的逻辑应用于您的代码.这意味着使用 blob 而不是 src={uploadedFiles[0]}.

<身体><p>选择视频文件... </p><input type="file" id="fileChooser" accept="*/*"/><div><a id="aTag"></a>

<脚本>document.getElementById('fileChooser').addEventListener('change', onFileSelected, false);函数 onFileSelected(evt){var 文件 = evt.target.files[0];//文件列表对象var type = file.type;var fileURL = URL.createObjectURL(file);var reader = new FileReader();reader.readAsDataURL(文件);var tmpElement;//# 代表新的视频标签元素....变量路径;//将保存文件 BLOB 的 URL(不是文件路径)...reader.onloadend = 函数(evt){if (evt.target.readyState == FileReader.DONE){//# 更新文件路径...path = (window.URL || window.webkitURL).createObjectURL(file);//# 删除任何其他现有的媒体元素...var container = document.getElementById("aTag");container.removeChild(container.childNodes[0]);tmpElement = document.createElement("视频");tmpElement.setAttribute("控件", "true" );tmpElement.setAttribute("width", "800");//# 添加新创建的带有文件路径的 HTML5 元素tmpElement.setAttribute("src", path);container.appendChild(tmpElement);}};}</html>

Im trying to play a video uploaded by the user using the <video tag but it doesnt seem to be loading to the DOM for some reason. Here is my code:

function Videos ({uploadedFiles}){

    if (uploadedFiles) {
            console.log(uploadedFiles[0])
            return(
                <div>
                    <h3>Videos</h3>

                        <video controls width="400">
                            <source src={uploadedFiles[0]} type="video/mp4"/>
                            Your browser does not support HTML5 video.
                        </video>

                </div>
            )
    } else return(<div> <h2> No Video Uploaded </h2></div>)
}

When i do console.log(uploadedFiles[0]) i get y2mate.com - after_effect_countdown_10_seconds_iDO9J_3OVJ0_1080p.mp4 which should work inside the video tag as the src. My doctype is html. Any ideas where im going wrong?

"I'm trying to play a video uploaded by the user using the <video> tag but it doesn' seem to be loading to the DOM for some reason"

Try the way shown below and see if it works better. If successful, then apply a similar logic to your code. This means using a blob instead of a src={uploadedFiles[0]}.

<!DOCTYPE html>
<html>
<body>

<p> Choose A Video File... </p>
<input type="file" id="fileChooser" accept="*/*"/>

<div>
<a id="aTag"> </a>
</div>

<script>

document.getElementById('fileChooser').addEventListener('change', onFileSelected, false);

function onFileSelected(evt) 
{
    var file = evt.target.files[0]; // FileList object
    var type = file.type;

    var fileURL = URL.createObjectURL(file);

    var reader = new FileReader();
    reader.readAsDataURL(file);

    var tmpElement; //# represents new video tag element....
    var path; //will hold URL of file BLOB (not file path)....

    reader.onloadend = function(evt) 
    {

        if (evt.target.readyState == FileReader.DONE) 
        {
            //# update file path...
            path = (window.URL || window.webkitURL).createObjectURL(file);

            //# remove any other existing media element...
            var container = document.getElementById("aTag");
            container.removeChild(container.childNodes[0]); 

            tmpElement = document.createElement( "video");
            tmpElement.setAttribute("controls", "true" );
            tmpElement.setAttribute("width", "800");

            //# add newly created HTML5 element with file path
            tmpElement.setAttribute("src", path);
            container.appendChild(tmpElement);
        }
    };

}

</script>

</body>
</html>
