thanks you result.

There days I try to find out , where is worg, but i am failed. 

But I see gst_app_src_push_buffer result are GST_FLOW_OK. Please such pipeline
, it stilln't work good.

static gboolean write_frame(GstElement* appsrc)
{
    GstBuffer *buf;
    GstFlowReturn ret;
    char tmpbuf[176*144*2] = {0};
    buf = gst_app_buffer_new(tmpbuf, 176*144*2, gst_app_buf_free, tmpbuf);
    if( (ret = gst_app_src_push_buffer(GST_APP_SRC (appsrc), buf) )!=
GST_FLOW_OK)
    {
        printf("gst_buf push data error value is %d  \n", ret);
    }
    else
    {
        printf("gst buf pust data ok\n");
    }
    return TRUE;
}
static gpointer camera_capture_thread(gpointer data)
{
    do
    {
        if(g_quit)
        {
            break;
        }
        write_frame(data);
        usleep(200000);
    }while(1);

    g_thread_exit(NULL);
}

int main(int argc, char** argv)
{
    GMainLoop *mainloop;
    GstElement* pipeline;

    g_type_init();
    g_thread_init(NULL);
    gst_init(&argc, &argv);

   pipeline = gst_parse_launch("appsrc name=v_src ! ffmpegcolorspace !
ffenc_h263 name=v_enc ! ffmux_3gp name=mux location=test.3gp alsasrc name=a_src
!  audio/x-raw-int,channels=1,rate=8000 ! audioresample ! amrnbenc name=a_enc 
a_enc. ! mux. mux. ! filesink location=test.3gp", NULL);

    GstElement* v_src = gst_bin_get_by_name(GST_BIN(pipeline), "v_src");
    GstElement* a_src = gst_bin_get_by_name(GST_BIN(pipeline), "a_src");
    GstCaps* caps = gst_caps_from_string("video/x-raw-rgb, width=(int)176,
height=(int)144, framerate=  (fraction)25/2, bpp=(int)16, depth=(int)16,
red_mask=(int)63488, green_mask=(int)2016,
blue_mask=(int)31,endianness=(int)1234");

    gst_app_src_set_caps(GST_APP_SRC(v_src), caps);
    if(gst_element_set_state (pipeline, GST_STATE_PLAYING) ==
GST_STATE_CHANGE_FAILURE)
    {
    }

    GThread* capture_thread = g_thread_create(camera_capture_thread, v_src,
TRUE, NULL);

    sleep(10);
    g_quit = 1;

  if(gst_element_set_state (GST_ELEMENT(a_src), GST_STATE_NULL) ==
GST_STATE_CHANGE_FAILURE)
    {
    }
    gst_app_src_end_of_stream(GST_APP_SRC(v_src));
    if(gst_element_set_state (GST_ELEMENT(v_src), GST_STATE_NULL) ==
GST_STATE_CHANGE_FAILURE)
    {

    }

    if(gst_element_set_state (GST_ELEMENT(pipeline), GST_STATE_NULL) ==
GST_STATE_CHANGE_FAILURE)
    {

    }

    gst_element_get_state(pipeline, NULL, NULL, GST_CLOCK_TIME_NONE);

}


I run this programe , I found I only get audio data, at sleep time.   and i
could get appsrc data untill gst_element_set_state (GST_ELEMENT(a_src),
GST_STATE_NULL) 
is do.

THANK YOU VERY MUCH.
