  • Demande de création d’un canal

  • Ffmpeg hevc integration for UWP [closed]

    19 décembre 2023, par theGuNNeR2407

    Did anyone try to run ffmpeg decoding using d3d11va hardware acceleration and hevc input on Hololens 2 ? It works using both h264 and h265 on windows desktop and for h264 on UWP HL but for h265 it returns empty green image even tho Hololens supports both codec formats and on fmmpeg API side you should only change avcodec_find_decoder and av_find_input_format from h264 to hevc.

    


  • FFmpeg. avcodec_find_encoder(AV_CODEC_ID_H264) return false

    14 juillet 2016, par Иван Чванов

    The problem : I can not connect the h264 codec for encoding and decoding of frames.

    Description :

    I downloaded from here ffmpeg library https://ffmpeg.zeranoe.com/builds/, version dev.

    Connect it to your project QT :

    extern "C"
    
{
    
    #include 
    
    #include 
    
    #include 
    
    #include 
    
    #include 
    
}
    
    
    
#pragma comment (lib, "avcodec.lib")
    
#pragma comment (lib, "avformat.lib")
    
#pragma comment (lib, "swscale.lib")
    
#pragma comment (lib, "avutil.lib")

    Next prescribe av_register_all(); to include all codecs.

    Next, call the function : avcodec_find_encoder(AV_CODEC_ID_H264), returns false.

    In the ReadMe file, the library said that it was collected with —enable-libx264 and —enable-gpl compile the keys including h264 codec that is supposed to be.

    If the call : avcodec_find_encoder(AV_CODEC_ID_MPEG1VIDEO), it returns an object AVCodec, as it should.

    I use the MinGW compiler. OC Windows 7.

    How can I resolve or work around the problem ? Compile the library itself has not yet obtained. I understand you to connect sources and "poking" them, that too is meaningless.

    ** Once again, I will describe my problem : **

    I need to encode the codec h264 (can VP9) individual frames in one program, and then decode them in another program. You can use other libraries. The language C ++. It is necessary to use interframe compression codec, rather than simply pressed apart frames.

    Sorry for my english.

    Ideas. Advice. Suggestions.
