• How to to burn subtitles based image on video using 'overlay_cuda', ffmpeg video filter

  4 septembre 2020, par jgkim0518

  I have to burn subtitles based image on video using ffmpeg(v4.3) and cuda, hardware accelerator. I want to use 'overlay_cuda' in filter complex.

  


  It is my command.

  


  ./ffmpeg -init_hw_device cuda=cuda:1 -hwaccel cuda -filter_hw_device cuda -hwaccel_output_format cuda -i 2_dump.ts -filter_complex "[v:0]scale_npp=1920:1080,format=yuv420p[base_video];[base_video][s:3]overlay_cuda[resurlt_video]" -map "[resurlt_video]" -map 0:a -c:v h264_nvenc -f mpegts subtitle_test.ts


  


  But it's fail.

  


  These are output massage included error.

• Background transparency lost on new machine using matplotlib and ffmpeg

  23 octobre 2023, par Jan Turowski

  I am creating animated physics graphs with a transparent background for later use in a NLE. On my old machine at work they display and render with background transparency just fine. The exact same code however loses background transparency in the ffmpeg render on both my Linux and my Windows machine at home. The animations are displayed just fine on all machines.

  


  As I first thought it was a Linux issue, I tried to run the code on my Windows machine expecting it to work again. Unfortunately it did not.

• Using ffmpeg to overlay dvdsub subtitles

  7 mai 2019, par ib11

  I am trying to overlay a dvdsub file pair (*.idx + *.sub) to a video file.

  Here is the sub pair.

  This is the batch script with the command line I am trying to use :

  @echo off
  
  set srcVidFile1="myvideo.mov"
  
  set srcSubFile=mysub.sub
  
  set srcIdxFile=mysub.idx
  
  set destFile=D:\testsub.mp4
  
  
  
  ffmpeg.exe -i %srcVidFile1% -i %srcSubFile% -i %srcIdxFile% 
  
      -filter_complex "[0:v][1:s]overlay" -c:s dvdsub -c:v 
  
      libx264 -crf 24 -c:a aac -b:a 160K -ar 48K -strict -2 -y 
  
      %destFile%

  This however only accepts 720x576 VOBsub files. And also the color gets inverted.

  My video however is 1080p and do have a 1920x1080 VOBsub file pair, but when I trying use them, I get an error sub2video : rectange (xxx xxx xxx xxx) overflowing 720 576

  Looks like adding -canvas_size 1920x1080 before -i %srcSubFile% handles the error on the canvas size. But I can’t figure out the color.

  The full output :

  I would like to input the 1920x1080 VOBsub file pair and overlay it on the 1080p video with 24bit original colors.

  Can somebody give me the correct command line for this ?

  And as it seems that the VOBsub are low res, is there any means that allow overlaying 1920x1080 24 bit pngs using ffmpeg ?
