Does LSB steganography permanently change the pixels of the image?

When you encrypt an image using LSB steganography it alters a few of the pixels. My question is if say you input that image in a video using ffmpeg and re-encode the video plus the image will the pixels still be altered and be able to be decrypted or not?

It depends on the compression used during encoding. If it is lossless (https://en.wikipedia.org/wiki/Lossless_compression) the pixels will remain the same, if it is lossy they are very likely to be changed and information is lost.
