[vlc-devel] Lua Interface questions

[wangxiang]

hi,  everyone

I have some thoughts of the lua audio-filter design, and I need some
discussion with someone more familiar with the function interface.

like I have pass the filter to the functions:  Then the parameters like the
"aout_buffer_t * p_in_buf, aout_buffer_t * p_out_buf", should be passed by
what method ?

The key question is how the parameters should be passed and where to alloc
the memory.
Thanks!


*static int vlclua_aout_filter_resample( lua_State * L )
{
    vlc_object_t *p_this = vlclua_get_auout_filter_internal( L );
    /******* Enable the filters ********/
    aout_EnableFilter( VLC_OBJECT(p_this), "resampler",true);

    p_this->pf_do_work( aout_instance_t * p_aout, aout_filter_t * p_filter,
    aout_buffer_t * p_in_buf, aout_buffer_t * p_out_buf );



    return 0;
}


static int vlclua_aout_filter_channel_mixer( lua_State * L )
{
    vlc_object_t *p_this = vlclua_get_auout_filter_internal( L );
    /******* Enable the filters ********/
    aout_EnableFilter( VLC_OBJECT(p_this), "channel_mixer",true);





    return 0;
}



static int vlclua_aout_filter_converter( lua_State * L )
{
    vlc_object_t *p_this = vlclua_get_auout_filter_internal( L );
    /******* Enable the filters ********/
    aout_EnableFilter( VLC_OBJECT(p_this), "converter",true);





    return 0;
}*
