视频中的图像在不同计算机上处理时显示出细微的差异
我有一个小视频剪辑，我已经通过我的视频到图像软件运行了它，并注意到图像出现了不同。两组图像是相同的，都是以 1 秒的片段进行切割的。它们的不同之处在于其中一组图像似乎比另一组图像更亮。我试图思考是什么导致了这种微妙的差异，但我不知所措。
我想也许是因为硬件不同会导致这种情况，但我没有在 GPU 上做任何事情。我还认为这可能是正在使用的编解码器，但是如果使用相同的编解码器和信息以相同的方式对视频进行编码，那么解码真的会以这种方式影响它吗？
下面是该程序的列表：
- 拍摄视频并将其保存为 1 秒图像
- 使用 C# 中的 DirectX 加载视频并保存纹理。
- 视频是使用 MPEG-4 类似的压缩进行编码的，
我知道这可能没有太多信息，但我不知道在哪里可以看到。
非常感谢任何建议。
I have a small video clip that I've run through my video to image software and noticed that the images come out different. Both set of images are identical in which they are cut at 1 second segments. Where they vary is one of the images seem to be brighter then the other set. I'm trying to think what can cause this subtle difference, but I'm at a loss.
I thought that maybe because the hardware is different that would cause this, but I'm not doing anything on the GPU. I also thought that it could be the codec being used, but if the video is encoded the same way using the same codec and information then would decoding really effect it in this way?
Below is a list of what the program is:
- Takes a video and saves it out as 1 second images
- Uses DirectX in C# to load in a video and saves out the texture.
- Video is encoded using MPEG-4 similar compression
I understand that this may not be much information to go off of, but I am at a loss of where I can look.
Any advice is greatly appreciated.

我想说图像实际上并没有什么不同。 MPEG-4 解码不太可能使用任何 GPU 资源。嗯，可以对 MPEG-4 Part 10 进行硬件解码，但它也受到某些条件的限制。更有可能的是，该效果是由于以下原因（或两者）造成的：
I'd say that images are not actually different. It is unlikely that MPEG-4 decoding uses any GPU resources. Well, it's possible to hardware decode MPEG-4 Part 10, but it's subject to certain conditions too. Far more likely, the effect is due to on of the reasons below (or both):
