• How to compile BlackMagic SDK to FFMPEG

  22 août 2018, par Манаф Иракский

  In Mac OS 10.13 I have installed FFMPEG via
  brew install ffmpeg
  I have downloaded the latest BlackMagic SDK from BlackMagic websit.

  I am not sure how I can compile black magic SDK to my ffmpeg.

  Here is the update

• avformat/movenc : support writing iTunes cover image

  14 avril 2018, par Timo Teräs

  avformat/movenc : support writing iTunes cover image
  Fixes https://trac.ffmpeg.org/ticket/2798
  This makes movenc handle AV_DISPOSITION_ATTACHED_PIC and write
  
  the associated pictures in iTunes cover atom. This corresponds
  
  to how 'mov' demuxer parses and exposes the cover images when
  
  reading.
  Most of the existing track handling loops properly ignore
  
  these 'virtual streams' as MOVTrack->entry is never incremented
  
  for them. However, additional tests are added as needed to ignore
  
  them.
  Tested to produce valid output with :
  
    ffmpeg -i movie.mp4 -i thumb.jpg -disposition:v:1 attached_pic \
  
           -map 0 -map 1 -c copy movie-with-cover.mp4
  The cover image is also copied correctly with :
  
    ffmpeg -i movie-with-cover.mp4 -map 0 -c copy out.mp4
  AtomicParseley says that the attached_pic stream is properly
  
  not visible in the main tracks of the file.

• Load font into ffmpeg command for subtitle usage

  1er mars 2024, par X3R0

  How to set ffmpeg to use my font Poppings-Regular.ttf

  


  // Load Local ttf file of Poppings-Regular.ttf
const poppingsRepsonse = await fetch('./fonts/poppings.ttf');
const poppingsDataArrayBuffer = await poppingsRepsonse.arrayBuffer();
const poppingsUInt8Array = new Uint8Array(poppingsDataArrayBuffer);
// Write Poppings file to local ffmpeg virtual file system into folder /temp_fonts/
let fileWritten3 = await ffmpegRef.current.writeFile(
    "temp_fonts/poppins.ttf", poppingsUInt8Array
);
// Load selected font into my custom command into ffmpeg
const converted = await ffmpegRef.current.exec([
    '-i', "input.mp4", // Input File
    '-vf', "subtitles=subtitles.srt:fontsdir=/temp_fonts:force_style='FontName=Poppins-Regular,FontSize=24'",  // Burn subtitles into video
    "output.mp4" // Output File
])


  


  I keep getting an error saying that the font cannot be loaded into memory when running ffmpegRef.current.exec. not sure what I'm doing wrong here
