• FFMPEG - Non-monotonous DTS in output stream 0:0 ;

  5 juin 2019, par Arigato Manga

  I’m getting the below error when trying to merge 2 video files using ffmpeg

  Non-monotonous DTS in output stream 0:0;

  I have tried the below solutions but none of them helped,

  1. Converting the input videos to mts files and then merging
  2. Separating the audio and video channels and merging them
     individually

  Both the input files are separate splits from 2 different 2 hour long videos.

  After the DTS error I played the input files and both of them have a pause/struck type scene at the end of the video, which I think might be because of the improper split times.

  Below is the split command I used,

  ffmpeg -i input1.mp4 -ss <starttime> -t <duration> -c copy one.mp4
  
  ffmpeg -i input2.mp4 -ss <starttime> -t <duration> -c copy two.mp4
  
  </duration></starttime></duration></starttime>

  What I want is,

  1. Is there any way to avoid this error
  2. Is there an option in ffmpeg which will split the file to the nearest frame so that it will not create such pause/struck video

  Below is the ffmpeg output of the input video files that are merged,

  one.mp4

• array_merge() : Argument #2 is not an array after adding class into providers

  19 juin 2019, par Daman Mokha

  I am using pbmedia/laravel-ffmpeg as soon as I installed and added the providers and alias, it shows me the following error. This code was simply working on another machine

  array_merge(): Argument #2 is not an array

  I have tried the following things

  1. Composer update/ and Fresh install
  2. Cleaning the bootstrap/cache/
  3. Checked the config file for laravel-ffmpeg it’s there and fine
  4. Publish the config file using the artisan CLI tool : php artisan vendor:publish —provider="Pbmedia\LaravelFFMpeg\FFMpegServiceProvider"

  Here is the portion from laravel.log when I tried to run.

  [2019-06-19 00:34:40] local.ERROR: ErrorException: array_merge(): Argument #2 is not an array in /Users/damanmokha/edetyv2/vendor/laravel/framework/src/Illuminate/Support/ServiceProvider.php:59

  if I don’t add these providers it works fine, but then I am not able to use ffmpeg without that.

• Using HW accelerate video encoding

  9 juin 2019, par RoboGil

  I am trying to get ffmpeg HW acceleration on an UpBoard .
  It uses an Atom x5 z8350 processor and Intel HD 400 GPU

  I have also followed this tutorial in order to compile ffmpeg with libmfx enabled.
