Thanks so much for the quick reply~
Yes, the video orientation means rotation to handle recording cellphone
And could you please provide me with some hint about what to write in the
metadata box? I searched a lot but I haven't seen anything about storing
rotation information in mp4.
Thanks so much again~:P
