但是检查该目录下并没有mp4文件。

Don't use yolox_ s. Pth.tar, author's yolox.py didn't have get it_ Model () method,So the weight file cannot be loaded

But I can run image successfully?

flydragon2018 · 2021-07-22T07:20:55Z

it seems complain about video file format??

EmberaThomas · 2021-07-22T07:31:21Z

似乎抱怨视频文件格式？

估计是，那应该用什么视频格式呢

flydragon2018 · 2021-07-22T07:34:39Z

source code using either real time camera or video file.
I looked up the error message that it is meta info about video file.

flydragon2018 · 2021-07-22T07:52:45Z

I tried another mp4 file, it works. so It is about video file compatibility.

EmberaThomas · 2021-07-22T07:55:49Z

我尝试了另一个 mp4 文件，它有效。所以这是关于视频文件的兼容性。

I tried another mp4 file, it works. so It is about video file compatibility.

I use MP4 format about 280M. Because it's too big？Or could u show your operation?

flydragon2018 · 2021-07-22T08:02:41Z

no. similar to image file, there is meta info about whole video file. some have, some don't.
I downloaded another mp4 file, it works. same operation.

I tried several mp4 videos. But it couldn't work. Could u send me your video to try?

EmberaThomas · 2021-07-22T09:10:17Z

I don't know what happened. It works

monoloxo · 2021-11-23T03:20:02Z

我也是换了一个mp4后可以了。

monoloxo · 2021-11-23T03:40:59Z

我有两个摄像头，其中一个录的mp4都不行，另一个都行。。

xifen523 · 2022-01-06T09:06:42Z

这是什么问题呀解决不了我也遇到了

xifen523 · 2022-01-07T05:39:06Z

我写在这个博客里面了可以查看
https://blog.csdn.net/qq_43190806/article/details/122362243

或者有一个答复
tools/demo.py中的第219行，有这样一句，
save_path = os.path.join(save_folder, args.path.split("/")[-1])
当args.path不是"/"分割的时候，就会出错误，导致源文件被覆盖。
应该改成这样：
save_path = os.path.join(save_folder, args.path[len(os.path.dirname(args.path))+1:])
