• ffmpeg ip camera error invalid data found when processing the input

  4 décembre 2022, par mehdi

  I want to capture images from a remote ip camera (Dahua) using ffmpeg.
I am able to ping the camera ip and see it live on my browser.

  


  Using this command :

  


  ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:password@172.28.56.237:37777" -vframes 1 test.jpg


  


  gives this result :

  


  Splitting the commandline.
Reading option '-hide_banner' ... matched as option 'hide_banner' (do not show program banner) with argument '1'.
Reading option '-loglevel' ... matched as option 'loglevel' (set logging level) with argument 'debug'.

  in the camera settings the ports are :

  


  tcp: 37777
udp: 37778
rtsp: 554


  


  I also tried below commands, but the result was the same error :

  


  ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp://admin:admin110@172.28.56.237:37777/live" -vframes 1 test.jpg



  


  ffmpeg -loglevel debug -i "rtsp://admin:admin110@172.28.56.237:554/live" -vframes 1 test.jpg

result: Server returned 404 not found


  


  I tried this in arch linux and windows and got the same error.

• where is ffmpeg output file go ?

  15 juin 2021, par راجہ سفیان

  I am following that link http://adnan-tech.com/add-or-extract-audio-from-video-php-ffmpeg/
and according to that code I create file in php like that

  


  <form action="post_audio.php" method="POST" enctype="multipart/form-data">&#xA;                <div class="form-group">&#xA;                    <label>Select video</label>&#xA;                    <input type="file" class="form-control" required="required" />&#xA;                </div>&#xA; &#xA;                <div class="form-group">&#xA;                    <label>Select audio</label>&#xA;                    <input type="file" class="form-control" required="required" />&#xA;                </div>&#xA; &#xA;                <input type="submit" class="btn btn-success" value="Add Audio" />&#xA;            </form>&#xA;

  


  and my post_audio.php file

  


  $video = $_FILES["video"]["tmp_name"];
        $audio = $_FILES["audio"]["tmp_name"];
 
        $command = "C:\ffmpeg\bin\ffmpeg.exe -i " . $video . " -i " . $audio . " -c:v copy -map 0:v:0 -map 1:a:0 output.mp4";
        system($command);
 
        $command = "C:\ffmpeg\bin\ffmpeg.exe -i " . $video . " original-audio.mp3";
        system($command);
