Gray frames when taking snapshot
This problem occurs when I use video_take_snapshot method loading http-flv stream.
No this problem in the VLC player application loading http-flv stream.
Please send an example to reproduce the issue. Also, which verson of python-vlc, vlc, python and o/s?
os: ubuntu 18.04 VLC player: 3.0.8 python-vlc: 3.0.11115 python: 3.6
I record a video in my phone,please in the baidupan.

Sorry, that site shows and error https://pan.baidu.com/error/404.html ...

Please post a python script reproducing the problem. Or, try to play the video with the VLC app, take several snapshots that way and compare those.
in any case, it is unlikely to be a python-vlc issue and either a VLC or some other problem, e.g. network latency.

Did snapshots taken from the VLC app show the same issue? Plus, without a sample script, it’ll be difficult to provide any help.
