• Issue Type question, possibly bug or mistake, not sure.
I have a custom Deepstream app, and a few pipelines for different sources.
Problem is, on my webcam pipeline with mjpeg decoder I dont see any classifier/tracker labels or any custom labels that I add via nvdsmeta.
The bounding boxes are still being shown correctly.
More than that, when I step through gst-nvosd - I can see that the correct labels are getting placed into nvdsosd->text_params, and are sent to nvll_osd_put_text() without any errors.
Interestingly, when I use my other piplene (with a mp4 file decoder) - I can see everything.
Supposedly in both cases OSD is just getting an RGBA buffer and the drawing should just work,
and I don’t know what to look for.
The cam pipeline looks like this
Please help :)
edit: i noticed that the cam pipeline had a different memory type chosen - nvbuf-mem-default, so I made streammux use MEM_SURFACE_ARRAY. Didin’t help.
I didn’t spot any other differences from the working pipeline. Feels like HW/CPU mode issue, since rects are drawn ok, but I don’t see lines or text.
