推荐答案

似乎360video / VR标准仍在不断发展。本文 http：//labs.dash.umn。 edu / etc-lab / detection-spherical-media-files / （日期为2016年4月）建议检查照片/视频的EXIF属性可能会揭示元数据中的模式。有一些库可用于从文件访问EXIF数据，例如： https://github.com / exif-js / exif-js 。 PHP库也存在。菲尔·哈维（Phil Harvey）的网站（ http://www.sno.phy.queensu.ca/ 〜phil / exiftool / ）提供了大量信息和编码示例。有针对WIN，MAC和NIX的编译工具以及一个C ++库。根据个人经验，可以从JPEG文件读取EXIF值。我从未尝试过访问360 JPEG，但是据我了解，球形摄像机产生的照片文件不过是普通JPEG（尽管在没有360°观看器的情况下观看时图像会失真）。 Phil Harvey编写的EXIF工具显示了对mp4的支持。您也许可以使用该工具分析360个视频，以在元数据中查找可识别的模式。

It seems that the 360video/VR standards are still in flux. This article, http://labs.dash.umn.edu/etc-lab/detecting-spherical-media-files/, (dated April 2016) suggests that inspecting the EXIF properties of the photo/video might reveal a pattern in the metadata. There are libraries available to access EXIF data from files, such as this: https://github.com/exif-js/exif-js. PHP libraries exist as well. Phil Harvey's website ( http://www.sno.phy.queensu.ca/~phil/exiftool/) has a wealth of information and coding examples. There are compiled tools for WIN, MAC and NIX and a C++ library as well. From personal experience, EXIF values can be read from JPEG files. I have never tried accessing 360 JPEGs, but it is my understanding that the photo files produced from spherical cameras are nothing but regular JPEGs (although the images appear distorted when viewed without a 360 viewer). The EXIF tool that Phil Harvey has written shows support for mp4. You may be able to use the tool to analyze 360 videos to look for discernible patterns in the metadata.
