Closed sunguwei closed 2 years ago

sunguwei commented 2 years ago

using the following code to read the video data

video = EncodedVideo.from_path(filename)
video_data = video.get_clip(start_sec=start_sec, end_sec=end_sec)

and the following errors happened.

It might be that the particular video you are trying out on is corrupted.

Could you try another backed in EncodedVideo? like, video = EncodedVideo.from_path(filename, decoder='torchvision')

Please re-open the issue if the problem persists.
