[FFmpeg-devel] some question about cook decoder

[George Tung]

Hi:


Recently,I arrempted transplant the MPlayer to the ARM platform.
After Compiled.I can use the player to broadcast mp3 on the ARM  platform.
But cannot broadcast real audio.It seems that the cook decoder cannot work in ARM platform.

Here's the console information:
