JS 或 Node.js 如何进行视频截帧传到后台服务器。

Question

如题， 这个是可以实现的吗？ 前端直接获取当前视频的所有帧，并把每一帧当初一个图片，传到后台。

Answer 1

function fecthVideoThumbnail(entryid, index){
var filename = path.join(imageDir, entryid, index + videoSuffix);
var thumb = path.join(imageDir, entryid, "overview",index + thumbSuffix);
var thumbPath = path.join(imageDir, entryid, "overview");
if (!fs.existsSync(thumbPath)) {
fs.mkdirSync(thumbPath);
}
var that = this;
filename = filename.replaceAll("\\","\\");
var cmdthumb = thumb.replaceAll("\\","\\");
if(!fs.existsSync(thumb)){
exec("ffmpeg -ss 00:00:10 -i "+filename+" -y -f image2 -t 0.001 "+cmdthumb+"", function() {
console.log(arguments[0]);
console.log('success');
readFileEntry(thumb,that.res);
});
}else{
readFileEntry(thumb,that.res);
}

}
