I want to ues dsp to decode h264 with mplayer framework and I dont want to use VISA ,

I want to call dsp when mplayer supply a avpacket data to dsp for decoding data to call h264's process function. 

I  dont know how to write a makefile to compile the file(.c) which calls process function. and how to compile the file(.c).

Who can give a example about it ?

The .c file will be compiled to .o file or other format ?

Can you give me some suggestion ？

    Is there particular reason you are looking at mplayer for framework? My understanding is this is quite monolithic framework with no option of adding plugins as shared object libraries. 

    The more popular framework in embedded space has been Gstreamer framework as it provides plugin based architecture similar to DirectShow. Also, there is VISA based plugin available for Gstreamer that calls DSP side audio/video codecs including H.264. You can find sources on this at gstreamer.ti.com.

    because mplayer can play more file format than gstreamer does. And I don't want to use VISA api and it needs to use v4l2 video out. But my board is used framebuffer.

    How to write makefile for mplayer with dsp.

    And can you give a example how to use the decompressed data after VIDDEC2_process with h264 codec with xdm interface.
