MoviePy di ​​Django: Gagal membaca durasi berkas

Saya mencoba meneruskan data video yang diambil dari ModelsForm ke metode moviepy, namun fungsi VideoFileClip() tidak dapat membaca durasi file.

Saya telah memeriksa data yang saya ambil dan itu adalah nama yang benar. Saat ini masalahnya mungkin saya meneruskannya sebagai string. Namun, tanpa ini ia mengembalikan kesalahan: objek 'Splitter' tidak memiliki atribut 'berakhir dengan'

Silakan lihat kesalahan dan kode saya di bawah ini. Terima kasih atas bantuan Anda!

Kode Model.py

Saya memeriksa kode sumber paket yang Anda gunakan, dan meneruskan nama file tampaknya merupakan cara yang tepat untuk memanggil VideoFileClip   -  person Grand Phuba    schedule 01.04.2020

Tampaknya Anda hanya meneruskan nama file dari video yang diunggah, padahal Anda seharusnya meneruskan seluruh jalur ke file tersebut.

Coba salah satu cara berikut ini, namun apa pun itu, masalahnya sepertinya perpustakaan tidak dapat memuat file yang benar. Pastikan terlebih dahulu video diunggah ke folder media Anda. Jika Anda dapat memverifikasi ini, maka Anda tahu itu sekarang hanya masalah memuatnya.

Opsi 1 - Ubah tampilan

Dalam tampilan video_form_upload Anda, coba yang berikut ini

def video_form_upload(request):
    if request.method == 'POST':
        form = VideoForm(request.POST, request.FILES)
        if form.is_valid():
             instance = form.save()  # get the saved model
             splitter = Splitter(instance.video.path)  # get the video file from the saved model
             return redirect(`highlights`)
    ...

Opsi 2 - Ubah splitter

Di kelas Splitter Anda, baris 18, coba ubah dari

clip = mp.VideoFileClip(str(file))

to

clip = mp.VideoFileClip(file.path)

Itu masuk akal! Meskipun sepertinya jalurnya tidak ada: AttributeError di /highlights/ Objek 'Splitter' tidak memiliki atribut 'path' Apakah ada cara yang lebih baik untuk mengoperasikan video yang diunggah? - person Silreth; 02.04.2020
comment
Mencoba opsi satu dan berhasil dengan benar tetapi kembali ke kesalahan durasi. Saya telah memeriksa bahwa video tersebut diunggah ke lokasi yang benar, sepertinya sulit untuk memuatnya :/ Ada ide lain? - person Silreth; 02.04.2020
comment
Apakah Anda dapat mengonfirmasi bahwa Anda melewati jalur absolut file tersebut? - person Grand Phuba; 02.04.2020
comment
sebenarnya saya mengeluarkan apa yang dilewatinya dan dikirimkan melalui: ‹highlights.splitter.Splitter object at 0x000002313C68A490› daripada jalurnya - person Silreth; 02.04.2020

Bisakah Anda mengirim tangkapan layar dari kode Anda saat ini dengan pernyataan print/log dan hasilnya - person Grand Phuba; 02.04.2020
