  • Retrieving information from ffmpeg shell_exec command

    29 août 2012, par user1503606

    i am doing the following

    $output = shell_exec('/usr/local/bin/ffmpeg -i intro.mp3 2>&1'); 
    
echo "<pre>$output</pre>";

    This outputs

At least one output file must be specified

    i want to get the information to insert into a database album,artist,genre,title etc

    But all seperately

    i can get them by doing the following

    $output = shell_exec(&#39;/usr/local/bin/ffmpeg -i intro.mp3 2>&amp;1&#39;); 
    

    
$edit = explode(&#39;  &#39;, $output);
    
$edit = implode("@", $edit);
    
$edit = explode(&#39;:&#39;, $output);
    
echo "<pre>";
    
print_r($edit);
    
echo "</pre>";

    then running

    &lt;?php echo $edit[9]; ?>

    etc

    but this seems like a really bad way and annoying way to get values and sometimes the output is slightly different which messes with the outputs.

    Whats the best way to do this or am i stuck doing this ?

    At this step I have two problems :
    first is a warning during execution
    deprecated pixel format used, make sure you did set range correctly
    The second is the video do not work correctly in VLC (video is "black") but it work in wmp...

    Then I add an empty audio track :

    ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"

    After that I concat this video to others using complex filter .
    When I concat my videos I have this message :

    [output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.

    And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
    perhaps it is not related
    I don't know ...

    Here my concat command and execution log

    D:\test>ffmpeg.exe -threads 8 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary0.mp4" -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4" -i "D:\Records\2013-10-11_115

  • Encode loopback capture data in mp3 using ffmpeg in VC++

    16 octobre 2013, par NetCoder89

    I'm trying to work on loopback capture(What you hear) and record this file in mp3/aac format using VC++.
    - >I can capture audio and can create a .wav file i.e. not compressed but I want a compressed file so I'm encoding this through ffmpeg to write an mp3 file not a .wav.

    However I'm not getting any way to do it directly ?
    I referred this for loopback capture.

    Please share your experience and opinions.

    Thanks !
