我写这个问题是为了看看是否有人可能知道这段代码会发生什么。写了以下几行，目的是删除TS数据包的标头位，但是代码有几个问题。
这是代码：
static GstPadProbeReturn TS_Packet (GstPad *padd, GstPadProbeInfo *info, gpointer user_data)
{
guint8 *byte;
gchar *paquete;
gsize count_print=0;

if (GST_EVENT_TYPE (GST_PAD_PROBE_INFO_DATA (info)) != GST_EVENT_EOS){
buffer = GST_PAD_PROBE_INFO_BUFFER (info);
buffer = gst_buffer_make_writable (buffer);
gst_buffer_map (buffer, &map, GST_MAP_WRITE);
byte=(guint8 *)map.data;
while(count_print<map.size){
g_print("\n");
g_print("-Paquete numero del paquete: %d-\n",i);
i=i+1;

问题和怀疑：
1）当我添加更多分析元素＆＃34;拼接点标记＆＃34; eclipse不执行代码，somo显示行g：print，并完成。
2）条件if（n，n＆lt; 8; n ++）是否给它一个大于8的值只显示ts文件的有限数量的包，而不是全部。 有谁知道为什么会出现这些问题，或者以不同的方式做同样的事情呢？
答案 0 :(得分：0)
通过此修改，我现在可以调整8 188中的一个并查看所有项目。
