关键函数_数据结构.doc

关键函数：

truecast 项目中truecast.c：

plugin_control(void* args)； av_render 项|~l: 视频插件：

av render open;

pp->set_output_list = dxa

pp_set_output_list;

pp->set_param pp->num_inputs *pp->inputs =dxa_pp_so t_param; 〃实现视频和音频信号的同步=1;

=dxa_pp_input;

pp->close

pp->qucry

pp->clear_data =av_render_c】ose;

=av_rcndcr_qucry;

二 av_render_c1ear_data;

/// -- 查询一//

// --清楚数据一 //

pp->set_output_iist = av_render_set_output_list; // -- 设置输出列表 -- //

pp->get param

10 12

pp->set_param

pp->num_inputs *pp->inputs

* (pp->inputs+l)

=av render get param:

14 16 18 20

=av_rcndcr_sct_param;

二 num_inputs;

=av_render_vinput;

= av render ainput;

/// -得到参数~//处理声音和口型同步8

/// -设置参数-- // 1 7

// 一编号输入一 //

音频插件:

pp->pclass =PP CLASS DECODER;

pp->opcn =dxa_pp_opcn;

pp->close 二 dxa_pp_close;

pp->query =dxa_pp_query; // 频参数的赋值pp->clear data =dxa pp clear data;

/// 渲染器的设置

数据结构: //ttdefine ALLOW SUB OPTIONS 1
