Tool/software: TI C/C++ Compiler
Hello：
I will save a test.ts file locally and use the following gstream command to display it properly.
gst-launch-1.0 -v filesrc location=test.ts ! queue ! tsdemux ! h264parse ! ducatih264dec ! waylandsink
I try to use C language to write，The image is not displayed when compiling execution.
Here is my source code：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include <sys/types.h>
#include <sys/time.h>
#include <unistd.h>
#include <gst/gst.h>
int main(int argc, char *argv[])
{
GstElement *pipeline, *filesrc, *queue, *tsdemux, *h264parse, *ducatih264dec, *waylandsink;
static GMainLoop *loop;
gst_init(&argc, &argv);
loop = g_main_loop_new(NULL, FALSE);
pipeline = gst_pipeline_new("pipeline");
if (!pipeline) {
g_printerr("%d gst_pipeline_new error \n", __LINE__);
return -1;
}
filesrc = gst_element_factory_make("filesrc", "filesrc0");
if (!filesrc) {
g_printerr("%d gst_element_factory_make error \n", __LINE__);
}
queue = gst_element_factory_make("queue", "queue0");
if (!queue) {
g_printerr("%d gst_element_factory_make error \n", __LINE__);
}
tsdemux = gst_element_factory_make("tsdemux", "tsdemux0");
if (!tsdemux) {
g_printerr("%d gst_element_factory_make error \n", __LINE__);
}
h264parse = gst_element_factory_make("h264parse", "h264parse0");
if (!h264parse) {
g_printerr("%d gst_element_factory_make error \n", __LINE__);
}
ducatih264dec = gst_element_factory_make("ducatih264dec", "ducatih264dec0");
if (!ducatih264dec) {
g_printerr("%d gst_element_factory_make error \n", __LINE__);
}
waylandsink = gst_element_factory_make("waylandsink", "waylandsink0");
if (!waylandsink) {
g_printerr("%d gst_element_factory_make error \n", __LINE__);
}
g_object_set(G_OBJECT(filesrc), "location", "test.ts", NULL);
gst_bin_add_many(GST_BIN(pipeline), filesrc, queue, tsdemux, h264parse, ducatih264dec, waylandsink, NULL);
gst_element_link_many(filesrc, queue, tsdemux, h264parse, ducatih264dec, waylandsink, NULL);
gst_element_set_state(pipeline, GST_STATE_PLAYING);
g_main_loop_run(loop);
g_main_loop_unref(loop);
return 0;
}
I try to add the "--gst-debug = 4" parameter when executing, and the red section has an error message
