[MEncoder-users] Encoding .3gp video with mencoder

[Ross Clement]

Thanks. I have opencore-amr implemented. However, I don't know how to
make mencoder use that library to encoder audio. I can encode to amr

However, I've discovered that my phone can handle aac audio.

Also, I hope to flash the phone with third party firmware at a later
date. I'm told that there is this marvelous application called
"mplayer" that I will be able to use on my phone after flashing. That
should make encoding an AWFUL lot easier.

My phone is a Motorola Rokr E8.
