Having issues with VideoReader for certain videos (cannot create buffer source)

[trudramukerji14]

Thanks for the awesome package.

I'm having issues with the VideoReader function. Namely, I downloaded the following using yt-dlp: YouTube video which was saved as an mp4 video path attached below. I then tried the following code.

videopath = 'data/jJzILuaFu-0.mp4_trimmed.mp4' vr = VideoReader(videopath)

But got the following error below. I was wondering if I could get some advice on what to do here.

Uploading jJzILuaFu-0.mp4_trimmed.mp4…
