嗨 知道如何进行部分视频加密的人，我的意思是如何提取(查找)视频帧的二进制格式?如果有人知道，请回复.

解决方案

，如果您只想读取视频文件并对其进行加密，则只需将其读取为二进制文件，对其进行解密，然后再写回即可.

如果要加密单个帧，以便视频在普通媒体播放器中显示为垃圾，则必须提取每个帧，对其进行加密，然后重新生成视频文件.请注意以下两点:
1)结果文件可能很大！
2)再次解密帧的机会非常差.视频存储使用有损压缩技术，可能会破坏您的加密数据.

If all you want to do is read the video file and encrypt it, then just read it as a binary file, excrypt it, and write it back.

If you want to encrypt individual frames so the the video shows as rubbish in a normal media player, then you have to extract each frame, encrypt it, and then re-build the video file. Be aware though of two things:
1) The resulting file is likely to be very large!
2) The chances of decrypting the frames again is extremely poor. Video storage uses a lossy compression technique which will probably destroy your encrypted data.

You can find the info to extract the frames here: Extract Frames from Video Files[^]
