[MPlayer-users] mencoder and HD videos on multimedia player

[Mathieu Westphal]

Hello

I try again, i'm afraid so first one didn't pass as a new thread here.

I have a multimedia server provided by my isp ( Free , i'm French ),
wich has the capability to play movie on my television.

But this player cannot read chinese subtitles. So the current solution I
use is to rencode hard-coded sub movie (using mencoder) wich can be used 
without any
problem on the "freebox" .

Anyway, if it work well with standard movies and dvd, it do not work
with HD movie. I've tried lot of different video codec for the
reencoding, and some of them work well with mplayer, but non seems to 
work on the player.

However the ORIGINAL video play just FINE, without any problem.

So is there a "standard" way to encode high res movie with mencoder?
How to identify the codec of the original video so i can use exactly the 
same encoding?
Why my freebox cannot play HD video encoded with mencoder?


Anyway here are the information about the "freebox" :
