I set resize to 0 and it seems that fMMS now sends video to server. So, the resizing problem goes away.

However, server rejected it because "message size limit exceeded" or something like this.

Unfortunately, N900 camera makes video with 0.5MBytes per 1 sec... Need some unversal way to resize it, even with lowering quality and resolution.

BTW, is it possible to NOT apply resizing procedure in fMMS for video files? Or any file which can't be resized - just send it as is. It is not good to reconfigure "resizing" field each time depending from message type.
