Decoding Error

[paras1612]

Hi, I'm getting the following error while running the tracking_on_mot.py

Called with args:
Namespace(cfg_file='./cfgs/resnet101.yml', class_agnostic=False, cuda=True, dataset_year=['MOT16'], detection_interval=1, detection_sbc_model='./save/detection_sbc_101_4_1_9417.pth', detectors=['PRIVATE'], feature_crop_size=(1024, 7, 7), im_crop_size=(3, 120, 40), im_for_box=False, iou_or_appearance='both', large_scale=False, mGPUs=False, mot_dir='MOT', mv_crop_size=(2, 120, 40), mv_for_box=False, res_for_box=False, residual_crop_size=(3, 120, 40), save_detections_with_feature=False, set_cfgs=['ANCHOR_SCALES', '[1, 4, 8, 16, 32]', 'ANCHOR_RATIOS', '[1, 3]', 'MAX_NUM_GT_BOXES', '55'], stage=['val'], tracking_box_transform_sigma=1.5, tracking_model='./save/tracking_net_single_resnet18_mv_residual_2_10_6034.pth', vis=False)

Decode Error.
Decoding video failed

I have downloaded MOT16 images from the official website and converted the images into a video with 20fps and encoded that video using ffmpeg as described in pytorch-coviar repository. I believe that this could be the problem of encoder. Could you share the configuration and commands of ffmpeg encoding that you have used? And if possible, can you also share the link to the encoded video that can be used directly?

I met the same error. @paras1612 Have you fixed it?

@liuqk3 Could you please share your videos with us? I've been suffering this error for too long :(

I met the same error. @paras1612 Have you fixed it?

No, @pencilYi . I haven't fixed it.

No, @pencilYi . I haven't fixed it. I think I found a solution. You can try to use : (base) xxx@xxx:~/xxx/program/datasets/MOT16/train/MOT16-09$ ffmpeg -f image2 -i ./img1/%06d.jpg -c:v mpeg4 -f rawvideo -r 30 MOT16-09.mp4 I had forgotten to add the output format "rawvideo" so that the error occored, I think. I ran this command to encode a video 'MOT16-09.mp4'.

Why your output is "warming up, frame 1" and mine is "warming up, frame 110"? Have you changed the code ? @paras1612

It's "warming up, frame 110" according to the source code. But I changed it for some other reason. I was getting the same error even with the original source code.
