  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le 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 (...)

  • ffmpeg sdl output framerate too high

    1er juillet 2015, par dkrikun

    I’m using the following command-line to play a video via SDL :

    ffmpeg -i input.mkv -f sdl "Video"

    The video is being played too fast, ffmpeg prints that the framerate is 500 (not constant, just playing as fast as possible)
    I’ve tried to limit the framerate as follows, but none of this has any effect :

    ffmpeg -i input.mkv -r 25 -f sdl "Video"  
    
ffmpeg -i input.mkv -f sdl -r 25 "Video"  
    
ffmpeg -i input.mkv -framerate 25 -f sdl "Video"  
    
ffmpeg -i input.mkv -f sdl -framerate 25 "Video"  

    I’m using ffmpeg version ffmpeg-20150605-git-7be0f48-win64-static on Windows 7.
    ffplay input.mkv works pretty well.

    Thank you !

    EDIT : console output for ffmpeg -i input.mkv -r 25 -f sdl "Video" follows :

  • ffmpeg hardsubbing ass file into mp4 [migrated]

    14 juillet 2015, par Wee Leong Tay

    I am unable to hardsub a subtitle file into a mp4 file. The code that I used (which seems to work once or twice) is :

    ffmpeg -i "videofile" -vf "ass=assfile" -scodec copy "outputfile"

    As I understood it, it is a static build. I am using ffmpeg version :

    ffmpeg version N-70239-g111d79a Copyright (c) 2000-2015

    and --enable-libass appears in the configuration list.

    When I add "-v debug" to the command I can see how it’s parsing the options, and it seems to be understanding "-scodec copy" somehow :

    Reading option '-scodec' ... matched as option 'scodec' (force subtitle codec ('copy' to copy stream)) with argument 'copy'.

    Does anyone have any idea why is it not working ?

  • FFMPEG command to crop and transpose video comes out zoomed in bad quality

    15 juillet 2015, par Brian

    I’m trying to convert an mp4 video with dimensions usually 960x720 into a sqaure 480:480 video but it comes out looking squished usually, the command is

    "-y -i %s -vf crop=480:480,transpose=%d -threads 5 -metadata:s:v rotate=0 -c:v libx264 -crf 27 -preset ultrafast -c:a copy -bsf:a aac_adtstoasc %s";

    Am I missing something, do I need to down scale first or something ?

    **EDIT adding full console output. The ffmpeg command is updated, but the goal still remains the same, take an arbitrary video and square crop it
