为移动设备创建一个二进制文件扩展名阅读器 [英] Create a binary file extension reader for mobile

问题描述

它是一个古老的二进制文件扩展名，实际上是由 Inter-Tel Web Conference 软件创建的视频文件.它包含屏幕录制视频和语音音频，还可以在会议期间捕获键盘聊天记录、与会者和文档管理器窗口.它可以与网络会议软件包中包含的独立应用程序 Inter-Tel Collaboration Player 一起播放.

It is an ancient binary file extension, actually a video file created by Inter-Tel Web Conference software. It contains a screen recording video and voice audio, and also can capture the keyboard chat log, attendees and the document manager window during a conference. It can be played with Inter-Tel Collaboration Player, a standalone application included with the Web Conference software package.

我现在想做的是找到一种在移动设备上播放这些文件的方法，尽管 Inter-Tel Collaboration Player 提供以 AVI 格式导出文件，但我想知道如何为此制作命令行脚本，因为应用程序在 Windows 7、8、10 上存在很多问题，并且没有 Mac 操作系统版本.

What I am trying to do now is finding a way to play these files on mobile, although Inter-Tel Collaboration Player offers exporting the files in AVI format, I want to know how to make a command line script for that because the application have lots of problems with Windows 7,8,10 and don't have a Mac OS version.

为这种扩展创建新播放器的方法是什么?

What is the way to create a new player for that kind of extensions?

推荐答案

Linktivity 停止支持此应用，http://linktivity.com 甚至从网络上消失了..."

"Linktivity stopped support on this app, http://linktivity.com even disappeared from the web..."

它们似乎被 Mitel Software 买断了，所以现在一切都好了在 Mitel 品牌下.

It seems they were bought out by Mitel Software so now everything is under the Mitel brand name.

我只是想找到一种方法来操作这个文件扩展名，一个新的手机和电脑的好播放器"

要使用现代软件打开/编辑那些 .lrec 文件，您必须查看它们:

To open/edit those .lrec files with modern software you'll have to look at their :

• 协作产品.
• 统一通信产品.

我试过了:

• 联系他们只是为了仔细检查事实，但他们希望与销售人员进行实时电话交谈，因此这不是一种选择.我会是一个虚假的潜在客户，但你可以提供一个真实世界的问题(包括背景细节)，看看他们是否能解决它.
• 还为 Android 下载了 MiCollab 应用，但它在开始任何操作之前都需要登录详细信息(因此仅检查来自 PC 的 .lrec 文件是否可以在 Android 中打开是没有进展的).

• To contact them just to double-check facts but they expect a realtime phone conversation with a salesperson so it wasn't an option. I'd be a fake potential customer, but you can provide a real-world issue (with background details) to see if they can solve it.
• Also downloaded for Android the MiCollab app but it needs login details before even starting anything (so no progress to just check if an .lrec file from PC would open within Android).

导出视频以供移动播放:
我试过桌面软件.不幸的是，它不接受外部命令，因此无法制作接受多个 lrec 并返回多个 AVI 的脚本.

Export videos for mobile playback :
I've tried the desktop software. Unfortunately it does not accept external commands so there is no way to make a script that takes multiple lrecs and gives back multiple AVI.

唯一的选择是从 .lrec 字节中提取帧，然后使用 FFmpeg 之类的工具将图像(因为似乎是将图像抓取为帧)合并为一个.MP4 视频.然后可以在移动设备上播放 MP4.

The only option is to extract frames from .lrec bytes and use a tool like FFmpeg to combine the images (since appears to do image grabs as frames) into one .MP4 video. MP4 is then playable on mobile devices.

此外，您现有的任何 AVI 文件都应使用 FFmpeg 转换为 MP4.

Also any of your existing AVI files should be converted with FFmpeg to MP4.

您可以在此处下载 FFmpeg for Windows(只是大蓝色按钮，忽略其他选项)

You can download FFmpeg for Windows here (just the big blue button, ignore other options).

• 将 ffmpeg.exe 文件复制到诸如 c:ffmpeg 之类的文件夹中，然后将 avi 放在那里.
• 现在打开命令提示符并执行 cd C:ffmpeg 到文件夹，然后输入:
  ffmpeg -i filename.avi filename.mp4(替换 文件名，输入和输出首选)
• 如果您知道如何操作，只需将 ffmpeg.exe 路径包含到控制面板 PATH 设置中，以便可以从任何文件夹访问 FFmpeg(无需将文件移动到其自己的文件夹).

• Copy the ffmpeg.exe file to some folder like c:ffmpeg and put your avi's there.
• Now open Command prompt and do cd C:ffmpeg to reach folder, then type :
  ffmpeg -i filename.avi filename.mp4 (replace filename with preferred for input and output)
• If you know how, just include ffmpeg.exe path to Control Panel PATH settings so that FFmpeg can be accessed from any folder (no need to move files to its own folder).

附注:
我仍在研究如何获取帧这是一种没有规范的笨拙格式(字节顺序是大端，但条目值填充为小端，然后也不确定是否每两个或四个反转字节因为它像那样混合在一起，像素字节本身似乎有压缩，但它不是 JPEG，更像 ZIP 或其他).到目前为止，只有确认的字节用于视频宽度和视频高度.如果 .lrec 只包含屏幕录制，这似乎是可行的.

PS:
I am still researching how to get the frames it's an akward format without the specs (bytes order is Big Endian but then entry values are filled as Little Endian, then also not sure whether to reverse every two or four bytes cos it's mixed up like that etc and the pixel bytes themselves seem to have compression but it's not JPEG more like ZIP or whatever). Only confirmed bytes so far are for video width and video height. It seems doable though if the .lrec only contains screen recordings.
