VideoLan.Net:向后播放媒体/更改播放速度? [英] VideoLan.Net: Play media backwards / Change playback speed?

问题描述

我被赋予了新的要求，即我可以使该选项可用于反向播放媒体文件，并且可以增加/降低播放速度.

I have been given a new requirement that I make the option available to play media files in reverse, and the option to be able to increase/decrease playback speed.

我正在使用的程序依赖VideoLan.Net来满足我们所有的媒体播放需求，所以我的问题是:

The program with which I am working relies on VideoLan.Net to handle all our media playback needs, so the question I have is this:

使用VideoLan.Net，是否可以向后播放媒体，并且可以提高/降低播放速度?

Using VideoLan.Net, is it possible to play media backwards, and is it possible to increase/decrease the playback speed?

推荐答案

vlc无法反向播放媒体.

vlc can not play media in reverse.

使用LibVLC，肯定可以提高/降低播放速度:请参见libvlc_media_player_set_rate(float rate).

With LibVLC it certainly is possible to increase/decrease the playback speed: see libvlc_media_player_set_rate(float rate).

例如将0.5f用于半速，将1.0f返回至正常速度，将2.0f用于双倍速度，依此类推.

Use e.g 0.5f for half speed, 1.0f to return to normal speed, 2.0f for double speed and so on.
