I am using the paperclip gem to upload and resize images. This setup works fine. I am capable of displaying uploaded images. The problem comes when I try to resize the uploaded image

Here is a snippet from the model file 

  has_attached_file: picture,:. Size = & gt; {: Small = & gt; "150x150">.}   
 When I try to upload the image I get this error  
  photo / var / folders / gram / gram -SegRMHuOkSlYtTMkO8U +++ TI / -Tmp- / file.jpg Not recognized by the 'Identity' command.   
 I'm sure the file is JPG image data, JFIF standard 1.01, comment: "Producer: using GD- jpeg v1.0 (IJ"  < Here is the file order  
  file.jpg I'm not sure, but in our application we do the same thing and it works. Our code looks like this:   has_attached_file: image ,: styles = & gt; {= small = & gt; "280x173 #" ,: Medium => "635x393 #"}, convert_options = & gt; all = & Gt; "-Quality 80"}, # ,: default_style = & gt; moderate: default_url = & gt; "/images/study/nophoto.jpg" validates _tagment_size: image,: less_than => 10. megabyte is valid_datetime_type_type: image ,: content_type = & gt; ['image / gif', 'image / png', 'image / x-png', 'image / jpeg' , 'Image / pjpeg', 'image / jpg']   
 I see the difference, you may have to provide convert_options to be able to resize.

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
