Video to numpy array

[Sharan19]

Hi. Can someone please tell me how I can convert the video I have uploaded through file_uploader into NumPy array so that I can further process the video. I don’t understand how to deal with buffer or byte objects. Looking forward to your replies. Thanks in advance.

[EDIT] I want to run the following code with getting any errors:

video_file = st.file_uploader("Upload video",type=['mp4']
import imageio
video = imageio.mimread(video_file)

Hi @Sharan19 -

After you use the file_uploader widget, you will have a BytesIO buffer. To get the data from it, you need to read the buffer as shown here:

How to process .apk file uploaded using fileuploader?

Hi @allenpbiju, welcome to the Streamlit community! st.file_uploader returns a BytesIO object, which is a buffer, which isn’t one of the types that function accepts (as the error message indicates). To get the bytes from a BytesIO object, you need to read the buffer: a = APK(uploaded_apk.read())

Thank you for the reply. I already tried this. This works for images but when I do the same for videos, I get a empty numpy array each time I convert bytes to numpy.
