• ffmpeg lavfi distorted audio

  11 mars 2017, par John

  How to play audio at a normal rate ?

  First 2s play fine, then audio becomes distorted, it seems to speed up.

  ffmpeg -f image2 -loop 1 -framerate 25 -i example.jpg -lavfi "amovie=sample.aac:loop=0" -f flv rtmp://192.168.99.100:1935/live/mystream2

  Repeating audio with loop:0 returns `[flv @ 0000000000708220] Non-monotonous DTS in output stream 0:0 ;

  Thank you.

• Recursively Converting FLAC to MP3 Using FFmpeg While Maintaining Metadata and Directory Structure on Windows

  20 mars 2017, par elgo2006

  I’m trying to use FFmpeg to convert all of the .flac’s in my music library to .mp3’s while maintaining the metadata and directory structure of the original files. I’ve got everything working so far except for maintaining the directory structure.

  So far I have :

  @echo off
  
  rem Copies the original directory structure from F:\Music to D:\Music
  
  xcopy /T %1 %2
  
  rem Recursively converts files with .flac extension from F:\Music to .mp3 in D:\Music
  
  for /R %1 %%i in (*.flac) do (
  
      echo Currently converting "%%~nxi"
  
      ffmpeg -v quiet -i "%%i" -q:a 0 -map_metadata 0 -id3v2_version 3 -write_id3v1 1 "%2\%%~ni.mp3"
  
  )
  
  echo Completed.
  
  pause

  I feel like my issue is coming from having my FFmpeg output as "%2\%%~ni.mp3" , however I can’t get it to maintain the original directory structure. I have played around with dpni as options for the output, but then it does not convert correctly.

  The .bat is being executed from the command line as convert F:\Music D:\Music

  All music in the original directory has the structure F :\Music\Artist Name\Album Name\Song.flac and I want it to end up as D :\Music\Artist Name\Album Name\Song.mp3.

  Alternatively, is there a way to convert the .flac to an .mp3 within the same directory as the source file and then delete the flac ?

• video hosting with PHP api or PHP script for social network project

  17 avril 2014, par al404IT

  I have a project for a small social network where user can upload their videos, video should not be longer than 1 or 2 minutes but they need to be private and related to user that uploaded.

  Since uploaded video may be in many different format I have two options :

  • upload video and use ffmpeg to process them, can i find any PHP script that does that ? PROS I have my files on my server and I'm not dependent from third party CONS I guess is a real intensive task and I may need a quite good noting plan since the beginning of this project

  • use a video hosting service that provide API to upload and process video, i actually find vzaar.com that may seems to do what I need. PROS Scalable CONS I rely on third party for my contents

  since the project is a small social network it may be interesting this too opusphp.com, but i never user or read about

  can Vimeo PRO suite my needs ? Other suggestions ?
  In future it may be necessary to add a basic video editing function to trim uploaded video setting starting and ending point
