Video

I have problem into video module.
I am using op_video module & flv player.
movie is playing very well but it is not audioable.

Using following combination:
op_video module
ffmpeg install
flv player
lame codec
mp3 codec

I am also trying flash player & video module
But from video module it takes to long time for video uploading.
After increasing post_max size,upload size same problem for uploading.
