• FFmpeg "Could not open file" error message when processing with PHP

  22 juin 2022, par FlyingCat

  I am using ffmpeg to get the image from several video files. I got my ffmpeg codes ready but I got the following error when I exec my codes.

  



  ffmpeg version 0.8.6-4:0.8.6-0ubuntu0.12.04.1, Copyright (c) 2000-2013 the Libav developers

  I only show the error messages that have color highlighted. 
My code :

  



   $ffmpeg ="/usr/bin/ffmpeg";

 $image_source_path = '/test/project/test.mp4';
 $ALL_PLACE_WIDTH = 300;
 $ALL_PLACE_HEIGHT = 300;

 $image_cmd = " -r 1 -ss 00:00:10 -t 00:00:01 -s ".$ALL_PLACE_WIDTH."x".$ALL_PLACE_HEIGHT."   -f image2 " ;

 $dest_image_path = '/test/project';

 $str_command= $ffmpeg  ." -i " . $image_source_path . $image_cmd .$dest_image_path;
 shell_exec($str_command);


  



  It seems my Linux wants to me to switch to avconv. I am not sure how to fix these errors. Can someone give me a hint about it ?

  


• ffmpeg throws "cur_dts is invalid" error when trying to get stream from IP camera

  17 octobre 2022, par Max

  I'm trying to stream from an IP camera with the following ffmpeg command :

  


  const command = [
        '-loglevel',
        'debug',
        '-timeout',
        '10000000',
        '-rtsp_transport',
        'tcp',
        '-i',
        this.cameraInfo.url,
        '-c:v',
        'copy',
        '-c:a',
        'aac',
        '-f',
        'mp4',
        '-movflags',
        '+faststart+frag_every_frame+empty_moov+default_base_moof',
        "-min_frag_duration",
        this.livestreamSegmentDuration,
        'pipe:1',
    ];


  


  With this command I pass an output to another stream transformer and stream as HLS using "mp4" instead of "ts" to avoid transcoding.

  


  Everything works smoothly with different cams, but when I try to get the stream from "Meldana" (issue is related to all ip cameras of this manufacturer), it constantly throws the following error and does not stream :

  


  cur_dts is invalid st:0 (0) [init:1 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:1 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:0 (0) [init:1 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)
cur_dts is invalid st:1 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)

cur_dts is invalid st:1 (0) [init:0 i_done:0 finish:0] (this is harmless if it occurs once at the start per stream)


  


  Even though it does not work with ffmpeg, I can watch the stream just fine in VLC.
What might be the problem ? Is there anything that could be corrected in the ffmpeg command ?
