[MPlayer-users] How to build mplayer with multi-threaded video decoding

[陳鈞宇]

Hi Henry,

Thanks for your reply!

I typed "./configure | grep pthread" in terminal and I got
------------------------------------------------------
Checking for pthread ... yes (using -lpthread)
Checking for w32threads ... no (using pthread instead)
------------------------------------------------------

I type "dpkg -l | grep pthread" in termial and I got
------------------------------------------------------
ii  libpthread-stubs0       0.3-2   pthread stubs ... libc
ii  libpthread-stubs0-dev   0.3-2   pthread stubs ... files      
------------------------------------------------------

It seems that the libraries about pthread were properly installed.

The video file I want to play is in H.264 and HE-AAC LATM format.
(recorded from DVB-T)
I can play it with mplayer-mt installed from debian-multimedia and multithreaded video decoding works fine.
(But mplayer-mt cannot decode the audio format in HE-AAC LATM.)
I will read the documentaion for more detail information.

Finally, really thanks for your reply.
I'm poor in English.
I don't know how to show my appreciate in words.
Just Thanks!!!

Yu
