Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -

Is there a way to generate ffmpeg command-lines by analyzing an existing video file ?
24 décembre 2014, par PreservedMooseIs there a tool or technique that is able to generate a valid ffmpeg encode command, based on the properties of an existing source file ?
In other words, I’d like to take an H264 QuickTime file, run it through the aforementioned (possibly) mythical tool, and have it spit out an ffmpeg command line that can be used to encode another video that matches the exact specs of the source file.
Apple’s Compressor has similar functionality, where you can just drag a Quicktime file to the Compressor Presets window, and it will automatically create an encoding preset that matches the specs of that file.
Is there a similar way to achieve this with ffmpeg ?

ffmpeg - How to antialias webp/gif
19 août 2019, par theParanoidAndroidI am trying to use ffmpeg to produce an animated GIF/WEBP from a set of pngs. However, the output images have jagged edges that I would like to smooth out somehow.
The set of PNGs are of a rotating sphere, outputted from Blender. Here is one of the images (cropped to the edge to hide a company logo)
However, when using the following commands :
ffmpeg -i frames/%%4d.png -vf palettegen -y palette.png
ffmpeg -v warning -i frames/%%4d.png -i palette.png -lavfi "paletteuse,setpts=PTS" -y out.gif
ffmpeg -v warning -i frames/%%4d.png -y out.webpto generate .gif and .webp animations, the edges becomes jagged :
I can’t convert to .mkv and back or something, as transparency has to be preserved.
Can anyone help ?

Uncomplete path recognition (FFmpeg) [duplicate]
23 septembre 2022, par Francesco BattistiThe script should download an entire playlist (only one song for this test) from YT and convert all the downloaded MP4 to MP3 :


from distutils import extension
from pytube import Playlist
import os

link = input("Enter YouTube Playlist URL: ")

yt_playlist = Playlist(link)

for video in yt_playlist.videos:
 downloaded_file = video.streams.filter(only_audio=True).first().download(r"C:\Users\Francesco\Desktop\Music\JC's\+++NEW+++")
 file, extension = os.path.splitext(downloaded_file)
 # Convert video into .mp3 file
 os.system('ffmpeg -i {file}{ext} {file}.mp3'.format(file=file, ext=extension))



Now, when I put the playlist's url in input, the script downloads the song but it can't convert it because :


C:\Users\Francesco\Desktop\Music\JC's\+++NEW+++\Ariete: No such file or directory



but the right path is :


C:\Users\Francesco\Desktop\Music\JC's\+++NEW+++\Ariete - LULTIMA NOTTE Testo Lyrics



so it stops when is there a space in directory name...
