Howto edit/rotate Samsung/Android Videos in mencoder solution

Movie-Aspect is undefined - no prescaling applied.
videocodec: libavcodec (720x1280 fourcc=34504d46 [FMP4])
[mpeg4 @ 0x2c91c00] timebase not supported by mpeg 4 standard
Could not open codec.
FATAL: Cannot initialize video driver.

That is the error I would get, I thought it was a codec error something else.  By fluke I saw something about ffmpeg where someone recommended manually telling it to the "fps" and it worked.  My phone uses 30fps so I knew to do the following:

mencoder -fps 30  -vf rotate=1 -o output-copy.avi -nosound -ovc copy 25825.mp4
All I had to do was specify "-fps 30" and it worked whereas before the resulting video was just 1 frame with nothing basically.

This seems like it will be common with Samsung phones or maybe a lot of Androids.
