  6 juin 2023, par Nasir

  I am having an issue with nginx-rtmp-module exec ffmpeg command. i have followed the example on 
www.github.com/arut/nginx-rtmp-module

  



  /home/junaid/bin/ffmpeg -f video4linux2 -i /dev/video1 -c:v libx264 -an -f flv rtmp://127.0.0.1:1935/myapp/mystream


  



  the command is working fine in terminal

  



  Config file :

  



  rtmp {
server {
    listen 1935;
    ping 30s;
    notify_method get;

    application myapp {
    live on;
    allow play all;
    exec_static /home/junaid/bin/ffmpeg -f video4linux2 -i /dev/video1 -c:v libx264 -an -f flv rtmp://127.0.0.1:1935/myapp/mystream;      
 }
}


  



  Error log :
http://www.codepad.org/enD4wlZ9

  



  I have tried :

  



  

  • nginx running as root (have permission to execute ffmpeg)

  


  • using ip instead of localhost

  


  • using complete path to ffmpeg

  


  • executing bash file (having ffmpeg and echo commands : echo commands execute just fine) from nginx

  


  



  please help me resolve this issue

  


• How to use the QMediaPlayer module to connect to a rtsp stream ?

  19 juin 2023, par Daniela

  I'm creating an RTSP stream using FFmpeg :

  


  ffmpeg -f gdigrab -framerate 30 -probesize 100M -i title="" -c:v libx264 -preset veryfast -maxrate 1000k -bufsize 1000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 128k -f rtsp -rtsp_transport udp rtsp://...129:8554/stream


  


  and trying to connect to it using the Qt module QMediaPlayer.

  


  It stuck for many seconds when it read the line
player->setSource(QUrl("rtsp://....129:8554/stream"));

  


  and then debug this message :

  


  qt.multimedia.ffmpeg.mediadataholder: AVStream duration -9223372036854775808 is invalid. Taking it from the metadata


  


  Also, connect(player, &QMediaPlayer::errorOccurred print :

  


  Error: "Invalid argument"

  


  class MediaPlayer : public QObject
{
    Q_OBJECT
public:
    MediaPlayer (QObject* parent = nullptr) : QObject(parent)
    {
        player = new QMediaPlayer;
        player->setSource(QUrl("rtsp://....129:8554/stream"));
        connect(player, &QMediaPlayer::errorOccurred, this, [this](QMediaPlayer::Error error, const QString& errorString)
        {
            qDebug() << "Error:" << errorString;
        });

        videoWidget = new QVideoWidget;
        player->setVideoOutput(videoWidget);

        videoWidget->show();
        player->play();
    }

private:
    QMediaPlayer* player;
    QVideoWidget* videoWidget;
};


  


  Testing the exactly same streamUrl on vlc does work correctly.
I'm using Qt 6.6, and Win10. ffmpeg 6.0

  


  How I could debug this ?

  


• AttributeError : module 'ffmpeg' has no attribute 'load'

  23 avril 2023, par az-purplepen

  I'm having difficulty with ffmpeg. I've installed it properly (I think) but still get AttributeErrors.

  


  I used the online guide (https://ffmpeg.org/download.html), and doing pip install ffmpeg-python instead of pip install ffmpeg. I've verified the installation with pip show. I've also made sure to not name my files ffmpeg.py.

  


  However, when I try running the following commands in terminal, I get an Attribute Error. Any tips ? I've seen this question pop up before, but none of the tips have worked.

  


  >>> import ffmpeg&#xA;>>> ffmpeg.load(&#x27;cover.wav&#x27;)&#xA;Traceback (most recent call last):&#xA;  File "<stdin>", line 1, in <module>&#xA;AttributeError: module &#x27;ffmpeg&#x27; has no attribute &#x27;load&#xA;</module></stdin>
