问题描述

我已经下载了一个视频文件并记录了数据包到达时间.我想根据我录制的时间使用 VLC 播放视频.在 VLC 源代码中我应该调用哪个函数以及如何调用它?

i`ve downloaded a video file and recorded the packet arrival time. and i want to use VLC to play the video according to the time i record. which function and how should i call to do it in the VLC source code?

我的意思是当我们按下按钮打开视频文件时，VLC通常使用哪些功能来播放视频?因为它的源代码树中有很多文件和函数.

i mean usually which functions VLC use to play video when we press the button to open a video file? because there are so many files and functions in its source tree.

非常感谢.

推荐答案

您可以链接到 libVLC 并调用其中的函数.http://wiki.videolan.org/LibVLC_SampleCode_Thumbnailer 给出了一个使用这种技术的小型 C 程序示例打开电影，在电影中寻找时间，抓取一帧的 JPG，并将其保存到磁盘.只有几行代码.

You can just link to libVLC and call functions in it. http://wiki.videolan.org/LibVLC_SampleCode_Thumbnailer gives an example of a small C program that uses this technique to open a movie, seek to a time within the movie, grab a JPG of one frame, and save it to disk. It is only a few lines of code.

我不了解 Windows，但在 Mac 上，标头和共享库位于:在 VLC 应用程序包中:VLC.app/Contents/MacOS/include/vlc/vlc.h(以及该目录中的其他 .h 文件)，库位于 VLC.app/Contents/MacOS/lib/libvlc.动态库

I don't know about Windows, but on Mac, the header and shared library are at: in the VLC application package at: VLC.app/Contents/MacOS/include/vlc/vlc.h (and the other .h files in that directory) and the library is at VLC.app/Contents/MacOS/lib/libvlc.dylib

请注意，该库是 GPLv2，而不是 LGPL.我的理解是，如果您链​​接到该库，则需要以 GPL 形式发布您的程序.

Note that the library is GPLv2, not LGPL. My understand is that if you link to the library, you are required to release your program as GPL.
