  • ffmpeg output parse in batch script

    3 juillet 2016, par vlad2005

    I am totally unfamiliar with scripts in Windows, but are forced to use such a script. I would like someone to help me with the following problem. I want to process the output from ffmpeg command to save information about access an webcam to be used later.
    More precisely command is following :

    ffmpeg -stats -hide_banner -list_devices true -f dshow -i dummy

    and output is like this :

    [dshow @ 02cec400] DirectShow video devices (some may be both video and audio devices)
    
[dshow @ 02cec400]  "Microsoft LifeCam Studio"
    
[dshow @ 02cec400]     Alternative name "@device_pnp_\\?\usb#vid_045e&pid_0772&mi_00#6&2a15e69b&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global"

[dshow @ 02cec400]     Alternative name "@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\Microphone (High Definition Aud"

    Typically, the first two occurence for ”Alternative name” from DirectShow correspond to video and audio, so for simplicity I want these two information saved in two variables.
    In this example is :

    @device_pnp_\\?\usb#vid_045e&pid_0772&mi_00#6&2a15e69b&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global

    and

    @device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\Desktop Microphone (3- Studio -

    Can someone more experienced to help me with this task ?

  • Recursively run ffprobe to get codec types

    5 juin 2022, par Timothy Massing

    I modified @rojo code from here a little to look for h264/AC3 and to recursively run thru all the children folders. My only issue is that it always says the videos has h264 and AC3, but when I run the ffprobe command manually it states different. Am I missing something ?

    



    @if (@CodeSection == @Batch) @then
@echo off & setlocal

for /R %%f in (*.mkv, *.mp4) do (
    echo Testing %%f

    set ffprobe=C:\ffmpeg-4.0.2-win64-static\bin\ffprobe -v quiet -show_entries "stream=codec_name,height" -of json "%%f"

    for /f "delims=" %%I in ('%ffprobe% ^| cscript /nologo /e:JScript "%~f0"') do set "%%~I"

    set "pre=-hide_banner -fflags +genpts+discardcorrupt+fastseek -analyzeduration 100M"
    set "pre=%pre% -probesize 50M -hwaccel dxva2 -y -threads 3 -v error -stats"
    set "global="
    set "video=-c:v h264_nvenc"
    set "audio=-c:a ac3"

    if defined h264 if defined ac3 (
        echo %%~nf already in x264 + AC3 format.
    )

    if not defined h264 if not defined ac3 (

        if not defined ac3 (
            echo Already has AC3 audio.  Re-encoding video only.
            set "audio=-c:a copy"
        ) 

        if not defined h264 (
            echo Already has h264 video.  Re-encoding audio only.
            set "video=-c:v copy"
        )

        echo output "%%~df%%~pf%%~nf.new.mkv"
        echo C:\ffmpeg-4.0.2-win64-static\bin\ffmpeg %pre% -i "%%f" %global% %video% %audio% "%%~df%%~pf%%~nf.new.mkv"

        pause

        echo del "%%f" /f /q
        echo ren "%%~df%%~pf%%~nf.new.mkv" "%%f"
    )

)
@end // end Batch / begin JScript

var stdin = WSH.CreateObject('Scripting.FileSystemObject').GetStandardStream(0),
    htmlfile = WSH.CreateObject('htmlfile'),
    JSON;

htmlfile.write('');
htmlfile.close(JSON = htmlfile.parentWindow.JSON);

var obj = JSON.parse(stdin.ReadAll());

for (var i = obj.streams.length; i--;) {
    if (/h264/i.test(obj.streams[i].codec_name)) WSH.Echo('h264=true');
    if (/ac3/i.test(obj.streams[i].codec_name)) WSH.Echo('ac3=true');
}


    



    I had this working of a second then it stopped for not reason.

@echo off & setlocal & goto run
