.mp4 / Audio question

[cheech37]

Hi @ll

I'm looking to export some movies to different PVP's (portable video players)

My question is:

When a portable video player supports
video format = mp4
audio format = only mp3

will it play mp4 videos that are encoded with audio AAC ?

maybe a very dumb question, but i've read somewhere that
if a player supports .mp4 it doesn't matter which audio codec was used, it will play those mp4 no matter what, cause the audio is "build-in".

is this true ?

thank you all for you help )

No. As MP4 is a container, you need a decoder capable of handling the formats "contained" in that MP4.
If your PVP is not capable of AAC decoding, then you won´t be able to play the sound.
