    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.

  • Append multiple audio files into a single audio file with overlap

    4 octobre 2022, par user3564069

    I have been trying to make an application that takes an array of wav or mp3 files as an input.
I want it to then produce an output file of all the wavs or mp3's in sequential order they were added, but each wav added should overlap the previous wav file added by half a second.

    


    So it should be Wav1 -> wav2 -> wav3 = output.wav, but with the start of wav2 overlapping wav1 and wav3 overlapping wav2.

    


    I have tried to use SOX to create silence for each required duration per wav and then append it and outputted a new wav file and then join them all at the end, while this works it is incredibly slow.

    


    I am open to any suggestions IE FFMPEG.
I tried using suggestions here FFMPEG ADelay using a FFMPEG feature known as ADelay but i was unable to make it work past 2 input files

    ffmpeg : properly cleanup filter graph on init failure

    The filter field is often used to check whether a filter is
    
configured. If configuring the filter actually fails somewhere in
    
the middle of it, these fields could still be set to non-NULL, which
    
lead to other code accessing the half-configured filter graph, which
    
in turn could lead to crashes within libavfilter.
    

    Solve this by properly resetting all fields.
    

    This was triggered by a fuzzed sample after the recent changes. It’s
    
unknown whether this behavior could be triggered before that.

  • avcodec/nvenc : Add support for H.265 encoding

    avcodec/nvenc : Add support for H.265 encoding

    Sufficiently new nvenc hardware (GM20x or later) has support for H.265
    
encoding. This works the same as the H.264 encoder except the
    
codec parameters are different.
    

    Due to the fact that common codec parameters are not shareable, there’s
    
quite a bit of conditional logic you’d wish we could do without, but
    
such is life.
