推荐答案

请参见 ^ ].

您不会转换太多视频.您要做的是对它进行解码/解压缩，然后再次对其进行编码/压缩.特定于格式的算法通常位于CODEC库中.有时此类库包含在集合中或支持格式的集合.

您直接说的过程称为转码.

您最好是先熟悉一下这些概念，然后再使用 FFmpeg [ ^ ].

CP上还有一些很棒的资料，可用于.NET的DirectShow.

干杯.

You don''t convert video, so much. What you do is you decode/decompress it, then encode/compress it again. The format-specific algorithm usually comes in a CODEC library; sometimes such libraries come in a collection or support a collection of formats.

The process you''re speaking of directly is called trans-coding.

You''re probably best off starting by gaining some familiarity with those concepts, and to start off by making use of something like FFmpeg[^] before venturing into your own trans-coding adventures.

There''s also some great material here on CP for working with DirectShow from .NET.

Cheers.
