  • FFMpeg colorkey/chromakey

    29 février 2016, par Rafał Kowalczyk

    I’m trying to achieve the following effect :

    1. I’ve a static background texture (for example : sky).
    2. I’m playing using FFMpeg and SDL 2.0 libraries .avi file with explosion where all non-transparent pixels are simple black.
    3. I want to draw only non-transparent pixels on my background.

    I though I can use SetColor for FFMpeg single frame but in SDL 2.0 I can use colorkey only for surfaces and FFMpeg is using YUV420 pixel format.

    How should I proceed ? any code suggestions ?

  • vdpau : common support for managing the VdpDecoder in avcodec

    vdpau : common support for managing the VdpDecoder in avcodec

    Using the not so new init and uninit callbacks, avcodec can now take
    
care of creating and destroying the VDPAU decoder instance.
    

    The application is still responsible for creating the VDPAU device
    
and allocating video surfaces - this is necessary to keep video
    
surfaces on the GPU all the way to the output. But the application
    
will no longer needs to care about any codec-specific aspects.

  • Converting multiple audio files in different subdirectories using ffmpeg

    4 avril 2022, par Amartya Roy Choudhury

    I am trying to convert multiple .mp3 files stored in different folders to .wav file using ffmpeg. The .wav files will be stored in the folder where the .mp3 file is located

    &#xA;

    import os&#xA;folder = r&#x27;D:\S2ST_DataCollection-main\public\recordings&#x27; ##### root folder&#xA;&#xA;&#xA;count = 0&#xA;for dirname, dirs, files in os.walk(folder):&#xA;    for filename in files:&#xA;        filename_without_extension, extension = os.path.splitext(filename)&#xA;        if extension == &#x27;.mp3&#x27;:       ######## get all the mp3 files&#xA;            count &#x2B;=1&#xA;            os.system(r"C:\Users\amart\Downloads\Compressed\S2ST_DataCollection-main\public\music.bat") ###### use the mp3 to wav conversion stored as batch file&#xA;

    &#xA;

    My music.bat file

    &#xA;

    for %%a in ("*.mp3") do ffmpeg -i "%%a" -vn -c:a pcm_s16le  -ar 44100 "%%~na.wav"&#xA;

    &#xA;

    Note : I have used pydub but it is not working

    &#xA;

    If i use the batch command only in a folder it is working fine but my .mp3 files are located in multiple folder

    &#xA;

    Any kind of help would be greatly appreciated
