  • 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 (...)

  • How much CPU is FFmpeg consuming ?

    20 mars 2023, par Zeki Ünyıldız

    I want to find out how much CPU my FFmpeg process is consuming. Is there a parameter or implementation for this ?

    


    I have used various linux applications, but I did not understand anything clearly.

    


  • .mov file not playing on Mac [closed]

    15 août 2023, par evorg88

    I have exported a number of videos from a Bosch CCTV system. These cover a period of 24 hours, and are split into approx. 16 minute clips @ 650MB. The files outputted are of the .mov format.

    


    When I try to open any of these clips, the following happens :

    


      

    • Windows Media Player opens and presents a still image of the first frame, then closes after approx. 3 seconds. It doesn’t allow me to scroll through the video whilst it’s attempting to play.

      • 


    • QuickTime Player does the same as windows media player.

      • 


    • VLC allows me to scroll through the video, but doesn’t actually start playing. This also closes after a few seconds.

      • 


    


    All of the files show approx. 650MB file size, but zero second duration.

    


    I tried using VLC to convert one of the files to an MP4 type, and now it plays without issue !

    


    Note, I then tried converting the original .mov file to MP4 using ffmpeg due to its batch conversion capability, but this failed to output a file that would play.

    


    I understand I’ll need to convert all of the files to MP4 now (although I can’t understand the reason why), but it looks like VLC makes you convert them one at a time.

    


    If anybody can help me out with where I’m going wrong, or advice on a batch conversion method for Mac (M1) it would be hugely appreciated !

    


    Thanks !

    


  • How to lossless rotate video from Sony A7Rii in FFMPEG avoiding codec error ?

    12 janvier 2020, par Jeffs

    I have a bunch of videos filmed on a Sony A7Rii that are upside down and need to be flipped 180. I’d like to do this lossless and been trying to use the following command :

    ffmpeg -i input.mp4 -c copy -metadata:s:v:0 rotate=180 output.mp4

    I understand this updates orientation information in the metadata of the video file, avoiding the need to reencode. However, it is generating an error relating to the audio codec :

    [mp4 @ 000001db6a69cd80] Could not find tag for codec pcm_s16be in stream #1, codec not currently supported in container
    Could not write header for output file #0 (incorrect codec parameters ?) : Invalid argument
    Stream mapping :
    Stream #0:0 -> #0:0 (copy)
    Stream #0:1 -> #0:1 (copy)

    After some searching, I understand this is expected behaviour because the MP4 container isn’t supposed to have audio encoded with that codec. Unfortunately for me, that is how the Sony A7Rii produces files.

    What FFMPEG command will offer the best work-around ? Ideally I’d not re-encode the audio, but that would be tolerable if there is no other way.

    Thanks !
