• Uploading video with Rails/Paperclip to Heroku/S3

  17 octobre 2015, par Corey Tegeler

  I’ve been failing at uploading a video in production mode on Heroku for way too long, testing local works great with resizing and thumbnail creation. Images also work fine going to my S3 bucket, so the credentials are all okay.

  Here are the logs I usually get from the code used below. Incidentally, the attempt right before I got these logs (without changing any code and using the same test video), the video made it to AWS, just without the resizing or thumbnail creation. But that was the only time I have even made it that far, and this failed upload and 500 error immediately happened after.

  $ heroku logs

• spaces in ffmpeg bash script filename variables

  19 août 2015, par Tandy Freeman

  I am using OS X Yosemite. I want to make a simple bash script that allows me to transcode a video. Everything works well as long as a file is not located in a directory which has spaces.

  Here is my script :

  #!/bin/sh
  
  
  
  ffmpeg -i “$1” -c:v ffv1 -level 3 -g 1 -c:a copy “$1.mkv” 

  Initially, I did not have the double quotes around the variable, but I read some stack overflows that used this as a solution. I’d rather not have to alter the path or add slashes etc. I want to just run :

   ./script.sh filename.mov 

  Here’s the error I get :

  Kierans-iMac:~ bla$ ./firstscript.command "/Users/bla/Desktop/untitled\ folder\ 2/v210.mov.mkv"

• ffmpeg file conversion unreadable [on hold]

  16 août 2015, par rashadb

  I used ffmpeg to shorten a Videohive file from 14 seconds to 5 seconds with the following entry on the command line :

  ffmpeg -i 15_Shopping_VKV.mov -t 5 shoes.mp4 

  The file doesn’t work when I try to play it with Quicktime. Along with other Google searches, I looked at the following links in Stackoverflow for suggestions :

  https://stackoverflow.com/questions/25831944/unreadable-files
  
  https://stackoverflow.com/questions/4818681/ffmpeg-conversion-error
  
  https://stackoverflow.com/questions/22307229/ffmpeg-mp4-file-is-not-valid

  At this point I’m out of ideas to figure out what’s wrong, let alone how to fix the problem.

  Here are some additional details :

  I managed to edit a few other Videohive files but each file comes in slightly different format and although I’ve converted a number of other files with a similar entry or one that adjusts the codec to something web ready, I’ve been unable to successfully convert this file. Like all of the other original videohive files it is readily read by QuickTime. Only after the conversion does this file not work. All other files I’ve converted worked with the following conversions for example :

  ffmpeg -i mainfile.mp4 -t 5:00 rave.mp4 

  OR

  ffmpeg -i 00299.mov -c:v libx264 dating.mp4

  Here are a few additional details that may help :

  1) a link to the broken file

  2) The printout of ffmpeg process
