I need to convert videos from.mp4 to.mp3 format. And I need to cut off the unnecessary and noisy part of the videos to get.mp3 format from it.
If you know how to do it, do let me know.
Regards.
A:
Install ffmpeg, a free video/audio converter
ffmpeg is a free command line tool that lets you convert files from one format to another. You can use it to convert.mp3 audio files to.mp4 video.
ffmpeg -i path/to/video.mp4 -vn -acodec copy -y path/to/audio.mp3
Save the file path/to/video.mp4 as path/to/video.mp4.mp3 on your Mac or PC.
Use it to convert your video file to.mp3
ffmpeg -i path/to/video.mp4.mp3 -vn -acodec copy -y path/to/audio.mp3
Save the file path/to/audio.mp3 as path/to/audio.mp3.mp3 on your Mac or PC.
Q:
Django-Nonrel - What is the difference between the query methods, query and query_list
I'm reading the documentation for Django-Nonrel and in QueryMethods I see the two following methods in the doc:
query(alias) and query_list(alias)
Both seems to do the same thing, so what is the difference between them?
Thanks!
A:
query() is used to construct a query object based on a string. query_list() is used to retrieve a list of all items that match a given string.
>>> from django.db.models import Q
>>> str = 'Larger than 5'
>>> Q(size__gt=5)
>>> list(Q(size__gt=5))
[, ]
