• ffmpeg : Conversion to mkv with compatibility with Samsung BluRay

  23 mai 2020, par Yehor

  I have several videos (FullHD resolution) which I want to convert to mkv format and play on my Samsung BluRay Player (model BD-J5900).
Based on User Manual (http://media.datatail.com/docs/manual/252846_en.pdf , page 6) it supports mkv playing if codecs are :

  



  

  • Video : H.264 BP/MP/HP

  


  • Audio : MP3

  


  



  Thus, based on https://ffmpeg.org/ffmpeg.html the command to convert it into proper format is :

  



  ffmpeg -i input.avi -f matroska -vcodec libx264 -acodec mp3 output.mkv


  



  It converts, but file is not playable on player. It say "Video format is not supported".

  



  After checking info here : https://trac.ffmpeg.org/wiki/Encode/H.264 - I thought it may require some compatibility and change the command to :

  



  ffmpeg -i input.avi -f matroska -vcodec libx264 -profile:v baseline -level 3.0 -acodec mp3 output.mkv


  



  But it also didn't help - player demonstrates the same error.

  



  How to fix that ?
Thanks !

  



  Updated : 
Also tested following options

  



   ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -x264-params bluray_compat=1 -acodec mp3 output.mkv
 ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v high -level 4.2 -x264-params bluray_compat=1 -acodec mp3 output.mkv
 ffmpeg -i input.file -f matroska -vcodec libx264 -preset veryslow -profile:v baseline -level 3.0 -x264-params bluray_compat=1 -acodec mp3 output.mkv
 ffmpeg -i input.file -vcodec libx264 -vf format=yuv420p -preset veryslow -acodec mp3 output.mkv


  



  Also not supported.

• Scalable solution for converting an image sequence to video

  15 septembre 2020, par Jeanette

  We are developing a stop motion app for kids and schools.

  


  So what we have is :

  


  

  • A sequence of images and audio files (no overlapping audio, in v1. But there can be gaps between them)

  


  


  What we need to do :

  


  

  1. Combine the images to a video with a frame rate between 1-12 fps

  


  2. Add multiple audio files at a given start times

  


  3. encode with H265 to mp4 format

  


  


  I would really like to avoid maintaining a VM or Azure batch jobs running ffmpeg jobs if possible.

  


  Is there any good frameworks or third party APIs ?
I have only found transloadit as the closes match but they don't have the option to add multiple audio files.

  


  Any suggestions or experience in this area is very appreciated.

  


• Dynamically set pitches of an mp3 to the pitches of a sample mp3 using JavaScript

  7 juillet 2023, par Maker of worlds

  I am looking for a way set the pitch and tone of an audio file to the pitch and tone of a reference audio file. I can't seem to find a solution anywhere. an example would be if I used a reference and was some song, and the main audio was me talking, it would sound like my voice is talking along the pitch of the song.

  


  I tried the web Api but couldn't find a good solution.

  


  Thank you in advance !
