• ffmpeg converted x264 video shows sharply reduced color saturation

  3 novembre 2015, par xaphod

  I’m an ffmpeg noob. I did spend 30 mins googling stackoverflow though, and didn’t find an answer.

  My designer made me some videos, of animated drawings. They’re great, but huge. So I tried passing them through ffmpeg. They get 10x smaller and don’t look pixelated — great ! — but the color is greatly reduced. What’s bright red/pink in the original becomes washed out ashey-grey-red in the output, when I view it on my macbook, or in the app it’s going into (iOS — ie. on an iPhone 5S you can see the missing color). How can I get the color to stay the same(ish) ?

  ffmpeg -i original.mp4

  shows me this :

  ... and many others, but no luck.

  Original.mp4 is here : http://fuzzymunchkin.com/tmp/original.mp4

• 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

• CVAT error during installation of development version

  28 novembre 2022, par Raman

  I'm trying to install development version of CVAT according to official instruction but struggling at the step of requirements.txt applying :

  


  pip install -r cvat/requirements/development.txt


  


  ... with following error :

  What other options could be applied to fix it ?
