  • avformat/aacdec : enable probesize-sized resyncs mid-stream

    avformat/aacdec : enable probesize-sized resyncs mid-stream

    Before adts_aac_resync would always bail out after probesize amount
    
of bytes had been progressed from the start of the input.
    

    Now just query the current position when entering resync, and at most
    
advance probesize amount of data from that start position.
    

    Fixes #9433

  • FFMpegCore .Net cuts off the fist few ( 1.5) seconds of audio

    28 mai 2024, par Tim

    I want to use FFMpegCore to convert some audio files to raw pcm. I noticed that this always cuts off 1.5 seconds of my audio from the start. I check my input stream, saved it to HD all good. If use it from cli with the same arguments everything seem fine. I tried -ss 0, no luck. This behavior is observed with .wav (RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 44100 Hz), same issue with different sample rate. I tested mp3 works fine.

    


    public async Task<memorystream> ConvertToPcmStreamAsync(Stream inputStream)&#xA;{&#xA;    var outputStream = new MemoryStream();&#xA;    &#xA;    var audioInput = new StreamPipeSource(inputStream);&#xA;    var audioOutput = new StreamPipeSink(outputStream);&#xA;&#xA;    await FFMpegArguments&#xA;        .FromPipeInput(audioInput)&#xA;        .OutputToPipe(audioOutput, options => options&#xA;            .WithCustomArgument("-ss 0 -f s16le -acodec pcm_s16le -ac 1"))&#xA;        .ProcessAsynchronously();&#xA;&#xA;    // Reset the position of the memory stream to the beginning&#xA;    outputStream.Position = 0;&#xA;&#xA;    return outputStream;&#xA;}&#xA;</memorystream>

  • How to use custom function to calculate 'x' in ffmpeg crop

    17 septembre 2016, par Sasha Kastsiushkin

    ffmpeg docs have this example :

    crop=in_w/2:in_h/2:(in_w-out_w)/2+((in_w-out_w)/2)*sin(n/10):(in_h-out_h)/2 +((in_h-out_h)/2)*sin(n/7)

    To make it simpler, I will use named params and only affect output width and position x
    crop=w=in_w/3:x=(in_w-out_w)/2+((in_w-out_w)/2)*sin(n/10)

    The result will be the video that is 3 times shorter than original and it will ’float’ along the x axis thanks to that sin(n/10) function. x is evaluated for each frame and n(number of the input frame) will increase and change the x position dynamically.

    I’m trying to create a custom function, which will take n or t and based on it return some value of x.

    Please help me or perhaps this is not possible. I was trying to create a small bash script, which will do so unsuccessfully.

    Thank you
