    Préambule

  • Changer son thème graphique

    22 février 2011, par

    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.
    Le placement peut être modifié effectivement, mais cette modification n’est que visuelle et non pas au niveau de la représentation sémantique de la page.

  • FFmpeg with libx264 skipped many frames during re-encoding

    18 mai 2019, par Igor

    I found a strange problem with FFmpeg 4.1.3 when I re-encode this video file with libx264 and I use bitrate 8000k mode.

    ffmpeg -y -i src.mp4 -c:v libx264 -preset slow -b:v 8000k dst.mp4

    Source video (28 seconds) shows 3 images.

    After re-encoding I see only 2 images and 3rd image is missing. I tested in latest VLC player 3.0.6, MPC-HC, Media player in Windows 10.

    If I use crf video encoding instead of bitrate everything is fine.

  • Rewind problem after convert *.mp3 to *.aac

    29 août 2020, par Vitaly Vesyolko

    I need to prepare audio files in MP3 format for sending via WhatsApp to Android and iOS devices with the ability to pause and mainly rewind.

    


    To do this, I use the ffmpeg utility on my notebook with Linux Ubuntu installed. Conversion example is described in detail here FFmpeg command to convert MP3 to AAC.

    


    As a result, I get AAC audio files that cannot be rewound in the WhatsApp player. I tried to set different options that are responsible for the output sound quality, size, and so on. But the ability to rewind in the WhatsApp player disappears.

    


    Rewind - is to slide by finger the circular slider in the WhatsApp audio player widget.

    


    I also used the following online services :

    


      

    1. ONLINE-CONVERT

      2. 


    2. Convertio

      3. 


    3. ZAMZAR.

      4. 


    


    One of the first two in some cases saves files with the ability to rewind, but in most cases - without it. And it very likely depends on the original file size. This is a hypothesis - if the size is small, then it is possible to rewind the audio file in the WhatsApp player. In any case, this method is not universal.

    


    Please provide a universal solution to the task at hand - a CLI utility or a tool that would convert MP3 to AAC with the ability to rewind in the WhatsApp player. And please indicate which characteristics are responsible for the absence / presence of such functionality.

    


  • Unable to create a PPAPI (Pepper) video plugin -NaCl module failed - how to resolve ?

    27 novembre 2013, par ElHaix

    Google's Say Goodbye to Our Old Friend NPAPI blog post indicates that NPAPI plugin support will cease by the end of 2014 (in favor of PPAPI).

    We have considered the option of using the ffmpeg libraries to create our own video plugin to simply decode RTSP encoded H.264 video streams on the client - important because we need as near real-time video display (avoiding transcoding latency). Using the ffmpeg libraries, there is still a 3-5 second delay in decoding the stream, not as fast as running MPlayer with the -benchmark option.

    In trying Google's PNaCl recommendation, we just got the LOADING status and the following error :

    NativeClient : NaCl module load failed : PnaclCoordinator : Compile
    process could not be created : ServiceRuntime : failed to start

    Are there any other alternatives or suggestions to getting this working ?
