  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • QAudioSink play AVFrame data decoded by ffmpeg

    26 mai 2022, par liuyulvv

    I want to using QAudioSink to play PCM data decoded by ffmpeg.

    


    I first try to play a pcm file and I made it :

    


    Here is the override function readData of QIODevice

    


    qint64 PCMDevice::readData(char *data, qint64 maxlen)
{
    int len = m_inputFile.size();
    len = len < maxlen ? len : maxlen;

    m_inputFile.read(data, len);
    return len;
}


    


    And I get the right result, the file is playing.

    


    But I want to play AVFrame data from the memory :

    


    qint64 PCMDevice::readData(char *data, qint64 maxlen)
{
    AVFrame *res = getFrame();
    if (res == nullptr)
        return 0;

    // Something wrong here
    auto ret = res->nb_samples;
    memcpy(data, res->data[0], ret);

    delete res;
    res = nullptr;
    return ret;
}


    


    How to make AVFrame's data to the data that QAudioSink need ?

    


    I'm pretty sure I'm using the correct sample_fmt, sample_rate etc.

    


    Where is the data of the stereo AVFrame and how to copy it to the data correctly ?

  • How to detect black screen at play time in ijkplayer ?

    31 août 2019, par seaguest

    I am using ijkplayer,I am wondering if it is possible to know if current player is black screen at play time ?

    because some old model mobiles do not support hard-decode and get black screen, I need to know this case then switch to soft-decode.
