Adding multiple audio tracks and subtitles to dash manifest (mpd) with ffmpeg

≯℡__Kan透↙ 提交于 2021-01-29 09:01:30
问题 I'm trying to create a website to stream some videos. For each video, I extract video, audio and subtitles in 3 different folders. It happens that a video has multiple audio tracks and multiple subtitles. I did a lot of research and I don't know how to add all of them in the manifest. Right now, I use this command: ffmpeg -f webm_dash_manifest \ -i video1.mp4 -f webm_dash_manifest \ -i video2.mp4 -f webm_dash_manifest \ -i audio1.webm -f webm_dash_manifest \ -i audio2.webm -f webm_dash

如何才能改变偏执的性格?

通常来说性格偏执的人很难自我改变,因为这种性格形成于早年,历经多年的发展后才被自身认识到。这个形成的过程是漫长的,想要改变也是很困难的。但是如果有毅力去改变,也是能做到的。只是说难度挺大。 偏执量表 主要用于评估测试人的精神疾病和性格特征,分数极高者需要警惕精神疾病和人格障碍的可能性,分数偏高者则可能表现为性格上的固执,多疑,偏执。而分数过低则表现为测试人缺乏主见,自我心理强度弱化,容易盲从。在企业应用中,常用于排查不良性格及心理健康问题。 偏执狂量表 PA https://www.zxgj.cn/g/mpa 偏执型人格障碍测试 https://www.zxgj.cn/g/pzx 偏见量表 PR https://www.zxgj.cn/g/mpr 如何才能改变偏执的性格? 与他人坦诚相处,把自己的缺陷不足,展示出来,消除自己的心理障碍,这是第一步。其次就是热心的去帮助别人,赢得别人的尊敬,从中获取自己的价值感。战胜自己的虚荣心,快乐和幸福来源于自我,而不是外部。对他人宽容以待,不批评不毒舌。 为什么人的性格会变成偏执,固执,倔强呢? 偏执和倔强起源于不信任感,比如成长的过程中不断的收到挫折,失败,被侮辱被冤屈,而这种情绪不断的发酵,无法得到纠正,这是造成性格偏执的主要因素,尤其是在幼年时期,缺乏慈爱,经常被否定,被指责。 其次是自卑心理在作祟,不断的提高自己的要求,设置是苛刻

为什么视频网站的视频链接地址是blob?

两盒软妹~` 提交于 2020-04-29 12:33:07
自从HTML5提供了video标签,在网页中播放视频已经变成一个非常简单的事,只要一个video标签,src属性设置为视频的地址就完事了。由于src指向真实的视频网络地址,在早期一般网站资源文件不怎么通过referer设置防盗链,当我们拿到视频的地址后可以随意的下载或使用(每次放假回家,就会有亲戚找我帮忙从一些视频网站上下东西)。 目前的云存储服务商大部分都支持referer防盗链。其原理就是在访问资源时,请求头会带上发起请求的页面地址,判断其不存在(表示直接访问资源地址)或不在白名单内,即为盗链。 可是从某个时间开始我们打开调试工具去看各大视频网站的视频src会发现,它们统统变成了这样的形式。 拿b站的一个视频来看,红框中的视频地址,这个blob是个什么东西?。 其实这个Blob URL也不是什么新技术,国内外出来都有一阵子了,但是网上的相关的文章不多也不是很详细,今天就和大家一起分享学习一下。 Blob和ArrayBuffer 最早是数据库直接用Blob来存储二进制数据对象,这样就不用关注存储数据的格式了。在web领域,Blob对象表示一个只读原始数据的类文件对象,虽然是二进制原始数据但是类似文件的对象,因此可以像操作文件对象一样操作Blob对象。 ArrayBuffer对象用来表示通用的、固定长度的原始二进制数据缓冲区。我们可以通过new ArrayBuffer(length
