Hello @hnulmz3,
Thank you for reaching out! If you want to display real-time processing results while testing an MP4 video using detect.py
, you can modify the script to show the video frames with detections as they are processed.
Here's a step-by-step guide to help you achieve this:
Ensure you have the latest version: Make sure you are using the most recent versions of torch
and YOLOv5
. You can update YOLOv5 by running:
git pull
pip install -U -r requirements.txt
Modify detect.py
: You can add code to display each frame with OpenCV. Below is an example modification to detect.py
:
import cv2
from pathlib import Path
import torch
from models.common import DetectMultiBackend
from utils.datasets import LoadStreams, LoadImages
from utils.general import check_img_size, non_max_suppression, scale_coords, xyxy2xywh, strip_optimizer, set_logging, increment_path
from utils.plots import plot_one_box
from utils.torch_utils import select_device, load_classifier, time_synchronized
# Initialize
set_logging()
device = select_device('')
half = device.type != 'cpu' # half precision only supported on CUDA
# Load model
model = DetectMultiBackend(weights, device=device, dnn=dnn)
stride, names, pt = model.stride, model.names, model.pt
imgsz = check_img_size(imgsz, s=stride) # check image size
# Dataloader
dataset = LoadImages(source, img_size=imgsz, stride=stride, auto=pt)
bs = 1 # batch_size
# Run inference
model.warmup(imgsz=(1 if pt else bs, 3, *imgsz)) # warmup
seen, dt = 0, [0.0, 0.0, 0.0]
for path, img, im0s, vid_cap in dataset:
img = torch.from_numpy(img).to(device)
img = img.half() if half else img.float() # uint8 to fp16/32
img /= 255.0 # 0 - 255 to 0.0 - 1.0
if img.ndimension() == 3:
img = img.unsqueeze(0)
# Inference
t1 = time_synchronized()
pred = model(img, augment=augment, visualize=visualize)
t2 = time_synchronized()
# NMS
pred = non_max_suppression(pred, conf_thres, iou_thres, classes, agnostic_nms)
t3 = time_synchronized()
# Process detections
for i, det in enumerate(pred): # detections per image
seen += 1
p, s, im0, frame = path, '', im0s.copy(), getattr(dataset, 'frame', 0)
p = Path(p) # to Path
save_path = str(save_dir / p.name) # img.jpg
txt_path = str(save_dir / 'labels' / p.stem) + ('' if dataset.mode == 'image' else f'_{frame}') # img.txt
s += '%gx%g ' % img.shape[2:] # print string
gn = torch.tensor(im0.shape)[[1, 0, 1, 0]] # normalization gain whwh
imc = im0.copy() if save_crop else im0 # for save_crop
annotator = Annotator(im0, line_width=line_thickness, example=str(names))
if len(det):
# Rescale boxes from img_size to im0 size
det[:, :4] = scale_coords(img.shape[2:], det[:, :4], im0.shape).round()
# Print results
for c in det[:, -1].unique():
n = (det[:, -1] == c).sum() # detections per class
s += f"{n} {names[int(c)]}{'s' * (n > 1)}, " # add to string
# Write results
for *xyxy, conf, cls in reversed(det):
if save_txt: # Write to file
xywh = (xyxy2xywh(torch.tensor(xyxy).view(1, 4)) / gn).view(-1).tolist() # normalized xywh
line = (cls, *xywh, conf) if save_conf else (cls, *xywh) # label format
with open(txt_path + '.txt', 'a') as f:
f.write(('%g ' * len(line)).rstrip() % line + '\n')
if save_img or view_img: # Add bbox to image
label = f'{names[int(cls)]} {conf:.2f}'
plot_one_box(xyxy, im0, label=label, color=colors[int(cls)], line_thickness=line_thickness)
# Stream results
if view_img:
cv2.imshow(str(p), im0)
if cv2.waitKey(1) == ord('q'): # q to quit
raise StopIteration
# Save results (image with detections)
if save_img:
if dataset.mode == 'image':
cv2.imwrite(save_path, im0)
else: # 'video' or 'stream'
if vid_path != save_path: # new video
vid_path = save_path
if isinstance(vid_writer, cv2.VideoWriter):
vid_writer.release() # release previous video writer
if vid_cap: # video
fps = vid_cap.get(cv2.CAP_PROP_FPS)
w = int(vid_cap.get(cv2.CAP_PROP_FRAME_WIDTH))
h = int(vid_cap.get(cv2.CAP_PROP_FRAME_HEIGHT))
else: # stream
fps, w, h = 30, im0.shape[1], im0.shape[0]
save_path = str(Path(save_path).with_suffix('.mp4')) # force *.mp4 suffix on results videos
vid_writer = cv2.VideoWriter(save_path, cv2.VideoWriter_fourcc(*'mp4v'), fps, (w, h))
vid_writer.write(im0)
if save_txt or save_img:
s = f"\n{len(list(save_dir.glob('labels/*.txt')))} labels saved to {save_dir / 'labels'}" if save_txt else ''
print(f"Results saved to {save_dir}{s}")
print(f'Done. ({t3 - t0:.3f}s)')
Run the modified script: Execute the modified detect.py
script with your video file as the source:
python detect.py --source path/to/your/video.mp4 --view-img
This modification will display the video frames with detections in real-time. If you encounter any issues or have further questions, feel free to ask!

Question
Using decect.py to test MP4 video has only one result output and an intermediate 'Video 1/1 (469/486).......... 640x384 (no detections), text display of 80.6ms', what should I do if I want to display the video in real time?
