  • ffmpeg is failing to convert mov files from iPhone 4

    11 octobre 2014, par skat

    I’m having issue with converting mov files from iPhone 4.

    Running this command :

    It’s only happening for mov files. There are couple of tricky places it looks like it’s trying to take screenshot from a video.

    Maybe anyone witnessed anything similar and can give me a tip ?

  • How to convert iphone's caf to ogg on ubuntu

    24 novembre 2012, par Amure Pinho - Syncmobile

    i really need your support to solve that problem :

    We developed an iOS application that sends a sound file to our server and then, we share this audio.

    The problem is we didnt find any solution to convert the audio inside the iOS.

    We tought : Ok, thats a problem, but we can still convert the audio in the server right ?

    We are trying to make this using afconvert, ffmpeg but with no sucess.

    Do you have any basic guide or hint so we can write this in our server application and convert all the .CAF files to another format like OGG or MP3 ?

    Thanks a lot !

  • ffmpeg how to select just PCM/LPCM/WAV from all audio in an mkv-container ?

    26 mai 2022, par Martin

    I ATM want to optimize some MKVs and since PCM/LPCM can be losslessly converted to FLAC I would like to use ffmpeg to convert all of them to flac. But apparently also other sound types are in this MKV container - e.g. DTS-HD MA 5.1.

    


    How can I (without knowing which stream id the the PCM/LPCM files do have) still select all of them and convert just them into a new MKA file ?

    


    My script ATM looks like this :

    


    ffmpeg -i input.mkv -vn -c:a flac output.mka

    


    But this will also convert the DTS sounds which I dont want to.

    


    Is there a -sel:a pcm lpcm wav option or something similar, so select all audios that are PCM, LPCM, WAV ?

    


    EDIT :

    


    I also want to keep all "settings" as they are.
That is how they should be converted (losslessly) :

    


      

    • LPCM 2.0 24bits ➔ FLAC 2.0 24bits

      • 


    • LPCM 5.1 16bits ➔ FLAC 5.1 16bits

      • 


    • PCM 1.0 24bits ➔ FLAC 1.0 24bits

      • 


    • PCM 2.0 16bits ➔ FLAC 2.0 16bits

      • 


    • WAV 2.0 24bits ➔ FLAC 2.0 24bits

      • 


    


    So channels should always stay, exactly as bit depth. Bitrate obviously will be lower at FLAC
