  • FFMPEG Screen record using AMD GPU encoder in Arch linux

    23 décembre 2020, par Lucas Martins Soares

    I am trying to record my screen with the GPU encoder using the following command :

    


    ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1440x900 -i :0 -vf 'hwupload,scale_vaapi=format=nv12' -c:v h264_vaapi -qp 24 output.mp4

    


    But I get the following error :

    


    [h264_vaapi @ 0x565330f47580] Driver does not support some wanted packed headers (wanted 0xd,
found 0x1).

    


    the recording starts well but when i finish a 3 second video it takes 3 minutes to process and the
result is an almost slow motion video.

    


    My drivers :

    


    xf86-video-amdgpu 19.1.0-2
xf86-video-ati 1:19.1.0-2

  • Using batch, how would you iterate through an array that you don't know how many values it may contain to run a function on each individual variable

    10 mai 2017, par Jay1995

    I have a batch file creating an array of variables it gets from a textfile, as follows :

    for /f "skip=1 tokens=9 delims= " %%a in (%findfile%) do set "_%%a=yes"
    
set count = 0
    
for /f "tokens=1* delims==#" %%b in ('set _') do (
    
    set /a count+=1
    
    set x=%%b
    
    set location[!count!]=!x:~1!
    
)
    
set %location%

    I’m trying to get each variable from the array to be looped into a function individually, but have no idea how to do it !!

    The location array storing all the variables has to be called into a for loop and the function I’m trying to get it to loop into is an FFMPEG function :

    for %%i in (%location%\*.mp4) do (if not exist "%%~ni\" MD "%%~ni"
    

    
    ffmpeg -i "%%i" -vframes 1 -f image2 -start_number 0 
    
    "%%~ni\%%~ni_Summary_%%3d.jpeg"
    

    
)

    All HELP would be greatly appreciated

  • как сделать 8 d музыку -> ffmpeg [closed]

    3 janvier 2023, par имя фамилия

    Всех приветствую, подскажите как через ffmpeg создать трек 8D
8D музыка это - метод постобработки аудиозаписи, когда диджеи берут уже существующий трек и микшируют его, создавая эффект движения звука вокруг слушателя.
По сути, 8D-аудио эмулирует звучание surround-формата Ambisonics. Последний подразумевает, что слушатель находится в центре «акустической сферы», по краям которой расставлены источники звука. (на одном форуме спросил что такое 8D)

    


    Писал на форуме, там не знаю решения, пробовал найти в открытых источниках, но видимо таким вопросом не задавались
