`video_reader` core dumps on specific video #6204

Open datumbox opened 2 years ago

datumbox commented 2 years ago

🐛 Describe the bug

from torchvision.io import read_video
from torchvision import set_video_backend

path = "./3caPS4FHFF8_000036_000046.mp4"

set_video_backend("pyav")
video, audio, info = read_video(path)
print("pyav OK")

set_video_backend("video_reader")
video, audio, info = read_video(path)
print("video_reader OK")

Output:

PyAV OK
malloc(): memory corruption
Aborted (core dumped)

The video file is part of Kinetics400. You can download it from here. Other videos pass.

Dump from gdb:

Potentially related or duplicate to #5419

bjuncek commented 2 years ago

Hi all, So I've dug quite a bit into this for the past two weeks (and am continuing to do so), and there are a few confusing factors. The error, to the best of my tracebacks is coming the fact that returned data from FFMPEG is larger than the allocated tensor (which should be guaranteed based on the headers), but there is some sort of a mismatch.

what I can't seem to figure out is why that is happening. I've tried hi-res videos, didn't have an issue, but then a video from #6204 does. The codec looks the same as some other videos, and it passes the ffprobe without an issue.

I've been getting some help from collegues at QS so hopefully will be able to get to the bottom of this.

Just for reference I can decode the video successfully on a different environment than @datumbox
