Camera ID is always 0

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

This is the continuation of the other post. As it took me some time to update to latest Deepstream.

Device information is as follows

Device infos are as follow.

• Hardware Platform (Jetson / GPU)
Xavier
• DeepStream Version
6.0 (latest)
• JetPack Version
Package: nvidia-jetpack
Version: 4.6-b199
Architecture: arm64
• NVIDIA GPU Driver Version (valid for GPU only)
10.2

deepstream-app is used.
Inside deepstream-app’s function, tried to get camera id or source id

static void  all_bbox_generated (AppCtx * appCtx, GstBuffer * buf,  NvDsBatchMeta * batch_meta, guint index)
{
       for (NvDsMetaList * l_frame = batch_meta->frame_meta_list; l_frame != NULL; l_frame = l_frame->next) {
          NvDsFrameMeta *frame_meta = l_frame->data;
          guint stream_id = frame_meta->source_id;//frame_meta->pad_index;
       }
}

But it always show 0. I have 4 sources (video files). But why I am always getting 0 for frame_meta->source_id; and frame_meta->pad_index;
If I tried the same thing in gst-dsexample plugin, I can have different sources.

Hi,
Please ensure you set batch-size=4 to nvstreammux. The setting has to fit number of sources.

  batch-size          : Maximum number of buffers in a batch
                        flags: readable, writable
                        Unsigned Integer. Range: 0 - 1024 Default: 0
4

Yes it is 4.Pls see the whole file.

Hi,
We add the print in gstdsexample.cpp:

    for (l_frame = batch_meta->frame_meta_list; l_frame != NULL;
      l_frame = l_frame->next)
    {
      frame_meta = (NvDsFrameMeta *) (l_frame->data);
+ g_print("source id = %d \n",frame_meta->source_id);
#ifdef WITH_OPENCV

And can see source id from 0 to 7 with attached config file. Please give it a try.
source8_1080p_dec_infer-resnet_tracker_tiled_display_fp16_test.txt (7.3 KB)

Yes can see source ID from gstdsexample.
But now issue is from deepstream_app_main.c.
If you print source id from

static void  all_bbox_generated (AppCtx * appCtx, GstBuffer * buf,  NvDsBatchMeta * batch_meta, guint index)
{
}

all source ids are 0.
all_bbox_generated is inside deepstream_app_main.c.

Hi,
Please add your code to gie_primary_processing_done_buf_prob(). After nvmultistreamtiler the sources are composited into single source, so source_id is 0.

8

I put here as tracker is used.

static void
write_kitti_past_track_output (AppCtx * appCtx, NvDsBatchMeta * batch_meta)

Thanks

Hi,
Please add your code in write_kitti_output().
