  • Converting DVD image with subtitles to MKV using avconv

    16 janvier 2016, par Carlos Eugenio Thompson Pinzón

    This is the procedure I know to convert a DVD image to another videoformat (v.g. MP4) :

    1. concatenate the VTS_01_n.VOB files inside VIDEO_TS folder (for n >= 0) into a single VOB file.
    2. use avconv or ffmpeg in order to convert that VOB into another format.

    So far so good, however now I want to convert the DVD image with the subtitles. As far as I know the MKV format supports subtitles, so it seems an obvious choice. Alternatively I might use any other format with hard subtitles (subtitles as part of the video image).

    However, the subtitle encoding in the DVD image is dvdsub and I get the following error

    Only SUBTITLE_ASS type supported.
    
Subtitle encoding failed

    However, when running avconv -codecs I get :

    ...
    
 DES    dvdsub          DVD subtitles
    
...

    And the -c:s copy switch, while it prevents the command to fail, it does not seem to produce a subtitle that the player can understand.

    So, how can I create ass subtitles from dvdsub using avconv ?

    My VOB file has eight subtitle channels and two audio channels. The Ubuntu video app does not show any subtitles, and only the first audio channel seems to be working, do the DVD image might be broken.

    Another file, for a double-layer DVD, displays the Subtitle encoding error, however when using the -c:s copy switch it further displays :

    Application provided invalid, non monotonically increasing dts to muxer in stream 2: 49 >= 49
    
av_interleaved_write_frame(): Invalid argument

    Thank you in advance for any ideas on how to solve these problems.

    (I am using Ubuntu where ffmpeg is an alias for avconv. I know it is possible to install the real ffmpeg but so far I have not done so.)

    sendBook and saveBook should return the filename

    Rev. 2.13 - 2013-09-26
    
* Fixed : sendBook and saveBook returned boolean TRUE/FALSE depending on
    
if the sending was successful. The sanitized/used filename was never
    
exposed. The methods now return the filename used for sending, or FALSE
    
if it failed.
    
* Change : sanitizeFileName is now a public function.

  • Realtime ffmpeg shell output PHP

    26 septembre 2013, par matthew johnston

    Alright, I've been fighting this problem for a few days. Works fine on my local windows machine but, can't seem to get it to work on my CentOS server. My script grabs the duration of the video being converted and also grabs the current seconds it has processed inside of ffmpeg. However, it is only grabbing the "input file" of the ffmpeg output and stopping there. I have tried using both pipes (STDOUT [1] & STDERR [2]) for some reason ffmpeg likes to output on the STDERR pipe. Weird.

    $filename = "somefilename.tmp";
    
$descriptor = array(
    
    0 => array("pipe", "r"),
    
    1 => array("pipe", "w"),
    
    2 => array("pipe", "w")
    
);
    

    
$ffmpeg = "ffmpeg -i /var/www/spotloader/videos/flipped/tmp/".$file."_comb.ts -vcodec mpeg2video -acodec pcm_s16le -pix_fmt yuv422p -vtag xdvb -b:v 13000k -r 30000/1001 /var/www/spotloader/videos/flipped/tmp/".$file.".mov";
    

    
//open the process
    
$process = proc_open($ffmpeg, $descriptor, $pipes, NULL, $_ENV);
    

    
//if the process opened
    
if ( is_resource( $process ) == true )
    
{
    
    //get process status
    
    $procStatus = proc_get_status( $process );
    

    
    //if its running, let node know
    
    if ( $procStatus['running'] )
    
    {
    
        //nodejs socket, nothing wrong here
    
        $this->_sendSocket('converting', array('filename' => str_replace('.tmp', '', $file)));
    
    }
    

    
    //while the process is running
    
    while( $procStatus['running'] === true )
    
    {
    
        //there is output in the pipe
    
        if ( !feof( $pipes[1] ) )
    
        {
    
            //get the output
    
            $data = fgets($pipes[1], 128);
    
            //match the outputs duration and save it.
    
            if(preg_match('/Duration:\s([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches)) 
    
            {
    
                static $duration;
    
                $duration = $this->_convertToSeconds($matches[1]);
    
            }
    

    
            //match the outputs current encoding time
    
            if(preg_match('/time=([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches)) 
    
            {
    
                //convert to seconds works fine, so it is not included.
    
                $curTime = $this->_convertToSeconds($matches[1]);
    
                //nodejs socket, nothing wrong here
    
                $this->_sendSocket('update', array('percent' => round( ($curTime / $duration) * 100), 'filename' => str_replace('.tmp', '', $file)));
    
            }
    
        }
    

    
        //update process status
    
        $procStatus = proc_get_status( $process );
    
    }
    

    
    //nodejs socket, nothing wrong here
    
    $this->_sendSocket('converted', array('percent' => 100, 'filename' => str_replace('.tmp', '', $file)));

    Any ideas ? What needs changing from the switch from Windows to CentOS ?
