  • exec() just run when i access target php in browser

    28 septembre 2016, par Mohammad Shojaa

    i use this code to run another php for some work (ffmpeg convert)

        $binpath = get_option('binpath','/usr/bin/php');
    
    $command = $binpath." -cli -f ".ABSPATH."/videocron.php";
    
    exec( "$command > /dev/null &", $arrOutput );

    but when i upload a video and run this code don’t convert video for ever.

    but when i access to videocron.php from browser all videos i uploaded convert suddenly !!!

    i use alternative exec function(system(); exec(); passthru(); shell_exec();)
    and i check videocron.php by readable function, it is readable.

    even i change owner videocron.php to nobody user

    in mod_security log i get this error :

    [Tue Sep 20 23:01:11 2016] [error] [client 37.156.10.171] ModSecurity: Multipart parsing error (init): Multipart: Boundary not found in C-T. [hostname "codenevis.net"] [uri "/lib/upload-ffmpeg.php"] [unique_id "V@GAb38AAAEAAGrk2QoAAAAH"]

    but even i unistalll mod_security it don’t work automatically.

    but in all don’t convert video until i access to videocron.php from browser !

  • ffmpeg WAV to MP3 Conversion - Audio Distortion and Timestamp Troubles

    24 septembre 2016, par user27547

    I’m using this command to convert a wav to mp3 :

    ffmpeg -i in.wav -ab 64k out.mp3

    The resulting mp3 has audio distortions, most notably a slight stuttering every few seconds.

    Also, the times no longer match. If I seek to the end of the file, then skip back 10 seconds, I’m able to hear the last 10 seconds of the file. However, if I go back a further 10 seconds, it jumps to several minutes before the end. I can then skip forward past the supposed end time (e.g. 13:44:08/13:43:57). I figure that this means the estimated time is different than the actual time, but it’s encoded at a constant bit rate, so I can’t imagine why it’s having this problem.

    I would appreciate any input on how to correct these problems. Thank you.

  • SOX got nothing from SoundFlower

    12 septembre 2016, par xiaose

    For some reason on some comps SoundFlower does not catch audio.
    I.e. there are SoundFlower but when I switch input\output to the SoundFlower I cannot get any sound. I have got only not empty file without any sound.

    Okay, how I try to get the sound...

    Just FYI :

    $ system_profiler SPSoftwareDataType

    Software:

    Gonna check is AVFoundation works :

    $ ./ffmpeg -h demuxer=avfoundation

    Demuxer avfoundation [AVFoundation input device]:

    Gonna get list of AVFoundation audio devices :

: Input/output error

    Okay, we have SoundFlower in devices :

    [AVFoundation input device @ 0x7fda40421000] [2] Soundflower (2ch)

    Then I run AppleScript which gonna switch to the "SoundFlower (2ch)" :

    enableSF("input")

    enableSF("output")

    Where enableSF(stdname) is :

    on enableSF(stdname)    
    
    tell application "System Preferences"   
    
        -- activate 
    
        tell anchor stdname of pane "com.apple.preference.sound" to reveal  
    
        tell application "System Events"    
    
            tell application process "System Preferences"   
    
                tell tab group 1 of window 1    
    
                    delay 2 
    
                    set rowslist to selected of row of table 1 of scroll area 1 
    
                    set counter to 0    
    
                    repeat with id in rowslist  
    
                        set counter to counter + 1  
    
                        set rowName to (value of text field 1 of row counter of table 1 of scroll area 1)   
    

    
                        set output to stdname &amp; " " &amp; rowName   
    
                        set scrpt to "echo \"" &amp; output &amp; "\" >> ~/Desktop/ds.log"  
    
                        do shell script scrpt   
    

    
                        if (rowName is equal to "Soundflower (2ch)") then   
    
                            set selected of row counter of table 1 of scroll area 1 to true 
    

    
                            set output to "
    
                            !!! FOUND SF for " &amp; stdname &amp; " " &amp; rowName    
    
                            set scrpt to "echo \"" &amp; output &amp; "\" >> ~/Desktop/ds.log"  
    
                            log output  
    
                            do shell script scrpt
    
                            exit repeat 
    
                        end if  
    
                    end repeat  
    
                end tell    
    
            end tell    
    
        end tell    
    
    end tell    
    
end enableSF    

    In result I have got this :

    input Internal Microphone
    
input Line In
    
input Digi CoreAudio Device
    
input Soundflower (2ch)
    

    
        !!! FOUND SF for input Soundflower (2ch)
    

    
output Headphones
    
output Digi CoreAudio Device
    
output Soundflower (2ch)
    

    
        !!! FOUND SF for output Soundflower (2ch)

    It means that we switch to the SoundFlower. Actually the same can be done by hands, but the script is more reliable as for me.

    Okay, next we can try to save some audio via SOX :

    $ /Applications/sox-14.3.2/sox -d /Desktop/out.wav

    Input File     : 'default' (coreaudio)

Aborted.

    And, as you can see, the SOX gives me an empty file. Rather, it gives the data, but there is no sound.

    This happens on all OS from 10.10 to 10.11.6. Normal output should be this type :
