I am currently using zencoder and Amazon for storing jomsocial videos. Is it possible for jomsocial or zencoder to auto-detect the appropriate orientation for videos and correct it? I do not see a way to manually change the orientation either. Is there a way to do this?

Hi, John.

If you use Zencoder you should ask there :)
As for JomSocial, it uses FFMPG library to convert videos and don't check for orientation - if you want to change it, you'll need to do it before upload.

If you think it's crucial, please post feature request here: uservoice.jomsocial.com/forums/101561-feature-request
If you don't want to wait when it will be implemented in JomSocial, ask developer for help: www.jomsocial.com/jomsocial-developers

Do I also need to change orientation on photos before I upload them? I don't see a way to change orientation after upload.

Hi, John.

As for photos in galleries - no. Under photo you should have buttons to rotate image. (see att.)

As for avatars, yes, you need to rotate them before you upload. Sometimes you could notice that photos just uploaded as avatar are rotated. It's because they ware made rotated and their position was saved into exif data. So they may look properly rotated and displayed in Windows but after upload they will be in original position (saved in exif data). So make sure that photo for avatar is properly rotated.
