I have a model for Video:
class Video(models.Model):
title = models.CharField(max_length=75)
pubdate = models.DateTimeField(default=timezone.now)
original_video = models.FileField(upload_to=get_upload_file_name)
mp4_720 = models.FileField(upload_to=get_upload_file_name,blank=True, null=True)
converted = models.BooleanField(default=False)
And this is the views.py :
def upload_video(request):
if request.POST:
form = VideoForm(request.POST, request.FILES)
if form.is_valid():
video = form.save(commit=False)
video.save()
convert_video.delay(video.id)
return HttpResponseRedirect('/')
Lastly the tasks.py :
def get_upload_file_name(video):
name = video.title
name = name+'.mp4'
return name
from pyvid.settings import MEDIA_ROOT
@app.task
def convert_video(video_id):
video = Video.objects.get(id=video_id)
video_path = str(MEDIA_ROOT)+'/'+str(video.original_video)
convert_video_name = get_upload_file_name(video)
cmd = 'ffmpeg -i %s -codec:v libx264 -profile:v baseline -preset slow -b:v 250k -maxrate 250k -bufsize 500k -vf scale=-1:360 -threads 0 -codec:a libfdk_aac -movflags +faststart %s.mp4' % (video_path, convert_video_name)
subprocess.call(
cmd,
shell=True
)
video.mp4_720 = convert_video_name
video.converted = True
video.save()
The problem is, even though video.mp4_720
is to upload by the upload_to=get_upload_file_name()
, its just taking the value of convert_video_name file path (which is the converted video and is in the base directory of the project) but not uploading the new file to the path specified.
How do I upload the new converted file in to the filefield of mp4_720
with the uploaded path?
Thank you
1. upload_to
save image relative to your MEDIA_ROOT
( ref ). And this work only if you're uploading file using form but here, you are manually setting video.mp4_720
.
2.While converting video, you should save output in MEDIA_ROOT (you should provide absolute url ) but you are just providing file name, Modify your code:
video_path = str(MEDIA_ROOT)+'/'+str(video.original_video)
convert_video_name = get_upload_file_name(video)
output_path = MEDIA_ROOT + '/' + convert_video_name
cmd = 'ffmpeg -i %s -codec:v libx264 -profile:v baseline -preset slow -b:v 250k -maxrate 250k -bufsize 500k -vf scale=-1:360 -threads 0 -codec:a libfdk_aac -movflags +faststart %s.mp4' % (video_path, output_path)
MEDIA_ROOT
. Now your code should work as in statement video.mp4_720 = convert_video_name
is already relative to MEDIA_ROOT
. I hope this will solve your problem. I have to tested the code.
