in this case,these sample mp4 has only audio encrypted,but video is not encrypted.
i can't find some sample that video is also encrypted.
this is online stream from NBA Legal Pass site,i bought an account there watching games,but my connection is too slow,and i can't watch games in HD 720p quality,only 640x360p quality.
so i want to download those small mp4 to my HDD,and watch them when i come back home.
i have no problem downloading,but downloaded mp4 are all encrypted,there is no audio and even video is not moving,i mean ,both video and audio must be encrypted.
while i watch online,everything is fine.
but like i said,i need 720p quality, and i don't have fast internet connection,so i can't watch online,i need to download,and then watch.
this is personal use
so please help me if you know.thanks
