• lavf/http: handle case where the server returns a redirect during a seek

  13 avril 2015, par Rodger Combs

  lavf/http: handle case where the server returns a redirect during a seek
  txoffer (e.g. http://tori.aoi-chan.com/ ) redirects to the same URI on your
  
  first request, and serves the actual file on the second. It’s stupid, but AFAIK
  
  technically compliant. We’d previously see the server not handing back a Range
  
  header and return an error ; now, instead, we see that there’s a redirect and
  
  keep track of the offset we want while trying again at the new URL.

• create mp4 slide show on raspbian

  25 novembre 2020, par Ramin

  I have RPi running raspbian.
I want a solution to convert a folder of image files to an mp4 slide show video that can be played with omxplayer.
I did it with ffmpeg and following command :

  


  ffmpeg -y -framerate .1 -pattern_type glob -i '*.jpg' -c:v libx264 -pix_fmt yuv420p out.mp4


  


  It works with mpv media player but playing it with the flowing command with omx player does not do anything.

  


  omxplayer --loop --no-osd --win 0,0,128,224 --orientation 90 out.mp4


  


  I must use omx player to output on exact window and be compatible with older programs.
Not sure what would be the right way to do this. I have already a node js server running on Pi that I can use if needed.
Thanks

  


• Subtitles won't show on video after burning [closed]

  9 octobre 2023, par dra

  I'm trying to burn subtitles into a video using ffmpeg js and ffmpeg wasm in my NextJS app.
the issue is, after running the subtitles just won't show.
my code is as follows

  


  await ffmpeg.exec([
    '-i',
    `${fileName}`,
    '-vf',
    "subtitles=subtitles.srt:force_style='Fontname=Helvetica,PrimaryColour=&HFF00'",
    `${fileName}_final.mp4`,
])


  


  from the terminal it works as expected

  


  tried to run it on .srt and .ass files too, with and without font specification for both file types
