• FFmpeg - Merge two images (.png) to video (.mp4) doesn't work

  12 juin 2019, par Jokoe

  I want to merge two images (names are not numbered in a sequence) to a video, but the result includes only a video of the first image.

  I would appreciate any kind of help !

  ffmpeg.exe -r 1/5 -i image_x.png -r 1/5 -i image_y.png -codec:v libx264 -vf fps=50 video.mp4

  Output :

• Converting 2-channel .mov file to .mp3 with ffmpeg

  29 mai 2019, par Josh Earl

  I use Skype Call Recorder to record Skype interviews. The app saves files in .mov format, with 2 audio channels.

  When I submit these files for transcription, they always come back with just one channel transcribed.

  I need to 1.) merge the tracks, and 2.) convert the .mov file to .mp3 format.

  Right now the command I’m working with is :

  ffmpeg -i input.mov -map 0:a output.mp3

  I get the following errors :

   Invalid audio stream. Exactly one MP3 audio stream is required.
  
   Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

  What am I missing ?

  Here’s the full console output, if it helps :

• 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

  #11 {main} 

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