how can I get the length of an video in order to validate django form before upload can begin ?
10 juillet 2013, par GetItDoneI have an app running on heroku that allows users to upload videos, then I use ffmpeg to preform 3 tasks using celery and redis-to-go :
1) Check the format and if it isn't already mp4, convert it to mp4.
2) Extract a 3 minute clip, in mp4 format
3) Grab an image from the videoThe problem is that I want to verify the video length before the video is uploaded and the three tasks are run since I want to make sure all videos are at least 15 minutes, and if not I want to raise a ValidationError. So when validating the form, I want to do something like this :
def clean(self, *args, **kwargs):
data = super(ContentTypeRestrictedVideoField, self).clean(*args, **kwargs)
file = data.file
try:
content_type = file.content_type
main, extension = content_type.split('/')
if content_type in self.content_types:
if file._size > self.max_upload_size:
raise forms.ValidationError(_('Please keep filesize under %s. Current filesize %s') % (filesizeformat(self.max_upload_size), filesizeformat(file._size)))
if VIDEO_LENGTH < MINIMUM_LENGTH:
raise forms.ValidationError(_('Please make sure video file is at least %s. Current video length %s') % (MINIMUM_LENGTH, VIDEO_LENGTH)
else:
raise forms.ValidationError(_('File type is not supported. File must be mov, flv, avi, mpeg, wmv, or mp4.'))
except AttributeError:
pass
return dataWhat could I do for VIDEO_LENGTH and MINIMUM_LENGTH ? I read that ffprobe could be used for getting the duration, but it isn't available with the buildpack I am using and I am very inexperienced. I can't just validate file size because it can vary greatly depending on numerous factors. Anyone have any solution as to what I could try ? Thanks

5 juin 2013, par Kamal SharmaI want to merge IMAGE + AUDIO and convert them into video using FFMPEG library,i compiled the library successfully,and got libfmpeg.so.but getting problem to execute the ffmpeg command through java code.This is command which i am using... "ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4" if i execute this ffmpeg command through CMD,my video.mp4 file is successfully created,but if exceute same command through my Activity,it doesnot create any file.
I used the code :

}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mpeg);
File mf = Environment.getExternalStorageDirectory();
String livestream = mf.getAbsoluteFile()+"smile.png";
String folderpth = mf.getAbsoluteFile()+"RABBA.MP3";
//String output="/home/saicomputer/game.mp4";
String output = new File(Environment.getExternalStorageDirectory(), "video.mp4").getAbsolutePath();
Log.i("Test", "Let's set output to " + output);
String cmd="ffmpeg -i "+ livestream +" -i "+ folderpth +" -acodec copy "+ output;
Log.e("chck plzzzzz", "after "+ cmd);
//String jaiho="ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4";
try{
Process p = Runtime.getRuntime().exec(cmd);
}
catch(Exception e)
{
System.out.println("exception"+e);
}and the logcat is
