  I have a form in django that I upload an avi movie and I want to convert to mp4 and save in media root and save path in database record :

  class Content(models.Model):
  
      content_title_en = models.CharField(max_length=255) 
  
      content_movie = models.FileField(verbose_name='movie')
  
  
  
      def save(self, *args, **kwargs):
  
          if self.content_movie:
  
              os.popen("ffmpeg -i C:/new/Wildlife.wmv video.mp4")
  
          super(Content, self).save(*args, **kwargs)

  and I convert file but I don’t know how save in file and my database record.

• Watson speech-to-text : Narrowband producing better results than Broadband ?

  22 juin 2017, par Irman A

  I’m using IBM Watson to transcribe a video library that we have. I’m currently doing initial research into it’s efficacy and accuracy.

  The videos in question have OK to very good sound quality and based on Watson documentation I should be using the Broadband model to transcribe them.

  I’ve however tested using both Narrow and Broadband and I’m finding that Narrowband always either slightly better or a lot better in some cases (up to 10%).

  Has anyone else done any similar testing ? It’s contrary to the documentation so I’m a little reluctant to just go ahead and use Narrowband for everything, but I may have to based on the results.

  I’m using ffmpeg to convert the videos to audio files to send to Watson, and the audio files show 48KHz sampling rates, which again means I should be using and getting better results using Broadband.

  Hoping someone out there has done similar research and can help.

  Thanks in advance.

• Html page for displaying video in mobile

  11 décembre 2012, par Viswa

  I am developing php pages for mobile, in one page i have to display video,
  now i am testing the php page in google chrome, but in Google chrome not playing mp4,avi,etc. chrome playing only ogg and ogv format.

  I heard about ffmpeg, i installed in my Ubuntu 12.4 environment,
  but it is also not converting to videos to ogg and ogv fromat.
  it converting other format like mp4,avi,ect.

  Displaying video using

   <video width="320" height="240" controls="controls" autoplay="true">
  
    <source src="/SeeSayDo/&lt;?php echo $model->av;?>"></source>
  
  </video>

  user may uploads any video format like avi,mp4,flv,etc, so i have to display any format they uploaded.
