  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

    Hello I have problems to change timecode insdie metadata of a video file "mov"

nombre=r"A019_02230134_C186.mov"
comand="ffmpeg -i " + nombre + " -ss 0 -map 0 -acodec copy -vcodec copy -timecode 01:20:10:00 -metadata:s:2:0 timecode=01:20:10:00 -metadata:s:1:0 timecode=01:20:10:00 -metadata:s:0:2 -metadata:s:0:2  timecode=01:10:10:00"+ " convert_" + nombre

os.popen(comand)


    


    I need to put muy own timecode to the file but this command not works.

    


    The console give me

    


      mov @ 00000225287fdc00] You requested a copy of the original timecode track so timecode metadata are now ignored
Output #0, mov, to 'convert_A019_02230134_C186.mov':

  • Piping images to FFMPEG using stdin causes artifacts

    15 avril 2021, par Michael Joseph Aubry

    I am sending images from puppeteer as a base64 buffer to stdin childProcess.stdin.write(frame); The images are piped one frame at a time inside a loop.

    


    This works well except I am getting weird artifacts and frames flickering — here is an example https://s3.us-west-2.amazonaws.com/storycreator.v2.rendered/cknhtqu2e0016niuuqmtu5u7b?t=0

    


    I've found when hardcoding a delay between each frames being piped that the artifacts/flickering is reduced.

    


    await new Promise((resolve) => {
  setTimeout(() => {
    resolve("done");
  }, 3000);
});

// then after 3s pipe the buffer
childProcess.stdin.write(frame);


    


    Another solution I found to solve the issue is to encode it as a .h264 then convert it to a .mp4. The problem is the video timing is drastically off.

    


    // The ffmpeg command
const childProcess = spawn(ffmpeg, [
  "-y",
  "-f",
  "image2pipe",
  "-pix_fmt",
  "argb",
  "-s",
  "1920x1080",
  "-r",
  `${fps ? `${fps}` : 100}`,
  "-i",
  "async:cache:pipe:0",
  "-an",
  "-vcodec",
  "libx264",
  "-pix_fmt",
  "yuv420p",
  "-r",
  `${fps ? `${fps}` : 100}`,
  "-y",
  `/tmp/${renderId}.mp4` // using .h264 seems to solve flicker but causes a weird framerate
]);
