• Open letter to the European Parliament’s LIBE committee

  An open letter to the European Parliament’s LIBE committee

  

  In an effort to stem the tide of external control over user privacy, Matomo has rallied with other like-minded companies like Protonmail, NextCloud, Tutanota and Mailfence, to advocate for pro-privacy changes to the European Commission’s “e-evidence” proposal.

  Excerpt from the letter : 

  “The Commission’s e-evidence proposal threatens the competitive advantage European tech businesses have over their American counterparts by undermining the protections we can provide to our customers. It breaks with the long-standing rule that only trusted national judicial authorities can order companies to hand over customer data for criminal investigations. Instead, the Commission’s e-evidence proposal would allow any foreign law enforcement agency from across the EU to force us to hand out customer data without our own authorities doublechecking the foreign order.

  “Different from American Big Tech firms, European privacy tech companies lack the resources to verify the legality of each foreign order. Because of the way the e-evidence proposal is phrased, we would not even be able to properly authenticate foreign authorities to ensure that we are not replying to a malicious actor – let alone object to an order if we found it to be unwarranted.”

  Matomo Founder, Matthieu Aubry emphasises, “It is time that privacy-minded tech companies work together to defend their users, their businesses, and the values they are founded on. This is why we are supporting Privacy Tech Europe.”

• avformat_open_input cannot open a file with raw opus audio data

  4 novembre 2020, par bbdd

  I have a problem when trying to open a binary file containing raw audio data in opus format. When I try to open this file, the library returns an error : Unknown input format : opus.

  


  How can I open this file ?

  


  I need to open it and write all the raw audio data to an audio container. I understand that the opus format is intended only for encoding. I realized this using command :

  


  $ ffmpeg -formats | grep Opus

ffmpeg version 3.4.4 Copyright (c) 2000-2018 the FFmpeg developers
  E opus Ogg Opus # For only encoding


  


  Then what format should I use to open this file ? With ogg ? I tried, but there are also problems with opening the outgoing file. I provide the code that shows only the necessary part to open the file :

  


  int main(int argc, char *argv[])
{
    // ...

    av_register_all();

    AVFormatContext *iFrmCtx = nullptr;
    AVFormatContext *oFrmCtx = nullptr;
    AVPacket packet;

    const char *iFilename = "opus.bin"; // Raw audio data with `opus` format
    const char *oFilename = "opus.mka"; // Audio file with `opus` audio format

    AVDictionary* frmOpts = nullptr;
    const qint32 smpRateErrorCode = av_dict_set_int(&frmOpts, "sample_rate", 8000,  0);
    const qint32 bitRateErrorCode = av_dict_set_int(&frmOpts, "bit_rate",    64000, 0);
    const qint32 channelErrorCode = av_dict_set_int(&frmOpts, "channels",    2,     0);
    if (smpRateErrorCode < 0 ||
            bitRateErrorCode < 0 ||
                channelErrorCode < 0) {
        return EXIT_FAILURE;
    }

    AVInputFormat *iFrm = av_find_input_format("opus"); // Error: Unknown input format
    if (iFrm == nullptr) {
        av_dict_free(&frmOpts);
        return EXIT_FAILURE;
    }

    qint32 ret = 0;
    if ((ret = avformat_open_input(&iFrmCtx, iFilename, iFrm, &frmOpts)) < 0) {
        av_dict_free(&frmOpts);
        return EXIT_FAILURE;
    }

    // We're doing something...
}
