如何在django中计算视频长度和视频缩略图

Question

我在做 django 项目。我正在尝试计算上传视频的长度并尝试创建视频的缩略图。如何做到这一点。

models.py

class Video(models.Model):
    video_format = models.CharField(max_length=15, blank=True, null=True)
    video_name = models.CharField(max_length=15, blank=True, null=True)
    video_size = models.CharField(max_length=15, blank=True, null=True)
    video_duration = models.IntegerField(blank=True, null=True)
    created_date = models.DateTimeField(default= datetime.now(), blank=True, null=True)
    status = models.CharField(max_length=15, blank=True, null=True)
    thumbline = models.CharField(max_length=15, blank=True, null=True)

views.py

def home(request):
    if request.method == 'POST':
        video = request.FILES.get('video')
        video_file = FileSystemStorage()
        file_upload = Video(video_file= video_file.save(video.name, video))
        file_upload.save()
        return render(request, 'home.html', {})

另一个建议是使用moviepy。

要获得持续时间，您可以使用VideoClipFile

from moviepy.editor import VideoClipFile

video = VideoClipFile(<path to your video file or a video file object>)

video.duration  # this will return the length of the video in seconds

要获取缩略图，您可以使用 Pillow 中的Image

from PIL import Image

frame_data = video.get_frame(1)  # 1 means frame at first second

img = Image.fromarray(frame_data, 'RGB')

然后对图像做任何你想做的事情。
