HTML5，分块视频流 [英] Html5, chuncked video streaming

问题描述

我的html视频调用了多个单独的块请求.似乎不像单流.

My html-video calls multiple separate request for chunks. seems not like single stream.

当我在调试工具中看到这一点时，

When I see that in debugging tools,

如您所见，有3个不同的通话.

As you see, there are 3 different call.

这是请求标头，

Accept:*/*
Accept-Encoding:identity;q=1, *;q=0
Accept-Language:ja-JP,en-US;q=0.8
Connection:keep-alive
Cookie:stg_domain_token=oNijQNByftcYnsLGzFZxRyCesLR-GdWKi6a-uKSJJ9060Yk8pwCiUlcHChyf
Host:stg.myhost.com
Range:bytes=32768-
User-Agent:Mozilla/5.0 (Linux; Android 6.0.1; SC-05G Build/MMB29K; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/54.0.2840.68 Mobile Safari/537.36
X-DevTools-Emulate-Network-Conditions-Client-Id:62626f5b-82c9-48b9-97f5-a7a983e1c3bc

这是响应头，

accept-ranges:bytes
Connection:keep-alive
Content-Disposition:filename=49976265106__9BB3FA25-04E4-4AF5-903C-9B12CF622567.MOV

有人知道我想念什么吗?

anyone know what I am missing?

推荐答案

浏览器一次不会下载整个视频或音频文件.它将它们分块下载并一个接一个地播放.

Browser won't download entire video or audio file at a time. It downloads them in chunks and plays them one after another.

为您的理解，我在这里解释标题.

For your understanding, I'm explaining the headers here.

请求标头

Accept:*/*:浏览器将接受任何MIME类型作为响应.

Accept:*/* : Browser will accept any MIME-Types as response.

Range:bytes=32768-:浏览器已经具有视频部分，直到字节32767，但需要字节32768中的文件.

Range:bytes=32768- : Browser already has the video part, till byte 32767 but requires file from byte 32768.

响应标题

status : 206:表示投放的内容是部分内容(不是完整的文件)

status : 206 : It means the served content is partial (not complete file)

accept-ranges:bytes:服务器仅接受字节范围(通用)

accept-ranges:bytes : Server accepts byte ranges only (which is universal)

Content-Length:324882:从请求的字节开始的总内容长度.

Content-Length:324882 : Total content length from requested byte.

content-range:bytes 32768-357649/357650:此格式的起始字节-最后一个字节/总长度(从0字节到结尾)

content-range:bytes 32768-357649/357650: it is in this format start byte - last byte / total length (from 0 byte to end)

Content-Type:video/quicktime:内容类型
