Thanks man here is the modified class :
I have added another method : is there any other way to deal with this abrupt ending, I saw some issues on gpro videos but i am reading at 30 fps |
.ts video attributes : Frame Width: 1920 |
I tried another approach where I am trying to set the frame but this also sets the frame from the total_frames it initially got :
|
Tried one more approach but still not able to skip the corrupted frame :
|
@pydev2018 ```python I understand that you are trying to skip corrupted frames in a video using YOLOv5. After reviewing your code, I have a few suggestions to consider:
Please give these suggestions a try and let me know if you still encounter any issues. Remember to adapt the code according to your specific requirements or constraints. Hope this helps!

Hi glenn @glenn-jocher , really appreciate your input , this if the modification to the next method which i did :
The output :
I am really stuck in this issue of not being able to skip the erroneous frames , I have also referred to : Still can't get it to work |
@pydev2018 hi glenn, I appreciate your efforts in modifying the After reviewing your code and the output, I noticed that the To resolve this issue, I suggest adding Here's the modified code snippet: # ...
while (not ret_val or im0 is None) and skip_count < max_skip_frames:
print(f"Skipping frame {self.frame} from video {path} due to read failure.")
self.frame += 1
skip_count += 1
ret_val, im0 = self.cap.read()
# If we've tried and failed to read many frames in a row, move to the next video or finish
if skip_count == max_skip_frames:
self.count += 1
skip_count = 0 # Reset counter
if self.count == self.nf:
raise StopIteration
else:
path = self.files[self.count]
self._new_video(path)
continue
self.frame += 1
skip_count = 0 # Reset skip_count after successfully reading a frame
# ... By resetting the Please give this modification a try and let me know if you still encounter any issues. Thank you! |
Hi glen , @glenn-jocher the issue still persists after adding another reset counter Interestingly when I make the image size 1280 it runs fine , when the processing time is 20 ms / frame , is it something to do with resolution ? Would really want to know your insights on why it's running on 1280 but not on 640 |
Hi @pydev2018, I apologize for the issue persisting even after adding the reset counter. Regarding the difference in performance between image sizes 1280 and 640, it's possible that the resolution is contributing to the issue. In general, higher resolution images require more processing time and resources compared to lower resolution images. This is because higher resolution images have more pixels, resulting in larger data to be processed. Therefore, it's not uncommon for performance to vary based on the image resolution. In your case, it seems that the model is able to handle the processing time of 20 ms per frame when the image size is 1280, but it struggles when the image size is reduced to 640. This could be due to the increased number of pixels in the higher resolution image. To further investigate why this difference in performance occurs, it would be helpful to have more context about your specific use case and the configuration settings of your model. This would allow us to provide more specific insights into the issue. If you could provide additional details, such as the specific YOLOv5 version you're using, the hardware setup, and any customizations or modifications you've made to the code, we can better understand the problem and guide you towards a solution. Thank you for bringing this to our attention, and we'll do our best to assist you further. |
hi glen it's not working on the 1280 video as well @glenn-jocher |
Hi @pydev2018, I'm sorry to hear that the issue persists even with the 1280 video. Could you provide more details about the problem you're experiencing? Specifically, it would be helpful to know any error messages or unexpected behaviors you're encountering when running the code with the 1280 video. Additionally, please share the specific version of YOLOv5 you're using and any customizations or modifications you've made to the code. This will allow us to better understand the issue and provide appropriate guidance. Thank you for your cooperation, and we'll do our best to assist you further. |

Question
I am trying to run object detection a a video that is being downloaded , the detection happens for sometime and then it abruptly ends , I have tried to modify the dataloader LoadImages class to no success :
Perhaps the video is still being downloaded from the stream (m3u8) in chunks and the dataloader is encountering an erroneous frame.
So I tried to modify the dataloader LoadImages class :
`class LoadImages:
def init(self, path, img_size=640, stride=32, auto=True, transforms=None, vid_stride=1):
if isinstance(path, str) and Path(path).suffix == '.txt':
path = Path(path).read_text().rsplit()
files = []
for p in sorted(path) if isinstance(path, (list, tuple)) else [path]:
p = str(Path(p).resolve())
if '' in p:
files.extend(sorted(glob.glob(p, recursive=True)))
elif os.path.isdir(p):
files.extend(sorted(glob.glob(os.path.join(p, '.*'))))
elif os.path.isfile(p):
files.append(p)
else:
raise FileNotFoundError(f'{p} does not exist')
`
Still got the same result :
explanation of modification :
This modified next method follows the logic you provided. It first attempts to read the next frame with the specified retries, and if it fails, it moves on to the next frame , I use the cap.read() method to achieve this , any help to handle this scenario @
