  • 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.

  • ffmpeg : Convertion to mkv with compatibility with Samsung BluRay

    25 octobre 2018, 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

  • Video and audio stretch calculations in ffmpeg

    30 janvier 2017, par garrettlynch

    I’m doing some extreme slow motion in ffmpeg on a video, both video and audio track, but can’t quite get my calculations correct.

    The input video is 00:06:41:00 at 24fps (9624 frames).
    I need the output video to be 34:00:00:00 at 24fps (2937600 frames).

    I tried these for the video and audio :

    setpts=305.237*PTS
    

    
atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.5, atempo=0.807668329177057

    However the video overshoots by 00:01:19:08 and the audio I’m unsure, on one player it stops somewhere around 8 hours but on another it just continues. What are the correct formulas ?

    Also on VLC the video has grey frames between video frames - do I need to interpolate to have continuous video frames ?
