hello,
I update deepstream6.0 to 6.3 recently, jetpack 4.6 update to 5.1.2, but application core dump sometimes, here is gdb dump. dump thread is app-source, then I try other api use gst_buffer_new_and_alloc instead gst_buffer_new_wrapped_full it will ok.
appsrc input like this:
#if 1
cv::Mat img = appsrc->inputQueue_->wait_and_pop();
if (img.data == NULL)
{
LOG_ERROR(“frame is nullptr, please check”);
return;
}
gstBuffer = gst_buffer_new_wrapped_full((GstMemoryFlags)GST_MEMORY_FLAG_PHYSICALLY_CONTIGUOUS,
(gpointer)img.data,
img.rows * img.cols * 1.5,
0,
img.rows * img.cols * 1.5,
NULL,
NULL);
else
// LOG_INFO(“request from local file”);
GstMapInfo map;
uint64_t frame_size = 2456 * 1500 * 1.5;
// LOG_INFO(“request width:{} height:{} size {}”,currentImage.cols, currentImage.rows,frame_size);
gstBuffer = gst_buffer_new_and_alloc(frame_size);
gst_buffer_map(gstBuffer, &map, GST_MAP_WRITE);
// memcpy(map.data, currentImage.data, frame_size);
FILE *fp = fopen(“ocr2456.yuv”, “rb”);
fread(map.data, 1, 5526000, fp);
map.size = 5526000;
gst_buffer_unmap(gstBuffer, &map);
fclose(fp);
endif
std::string name = “app-source” + std::to_string(appsrc->unqiuedId_);
GstElement *appsrcElemet = gst_bin_get_by_name(GST_BIN(appsrc->source_bin_), name.c_str());
g_signal_emit_by_name(appsrcElemet, “push-buffer”, gstBuffer, &gstret);
