  • Pas question de marché, de cloud etc...

    10 avril 2011

    Le vocabulaire utilisé sur ce site essaie d’éviter toute référence à la mode qui fleurit allègrement

    rtsp : Include an User-Agent header field in all requests

    Some rtsp servers like the IP Cam IcyBox IB-CAM2002 need it.

  • Hot to access video frames from external process ?

    14 août 2019, par gaamaa

    Windows 32 bit application memory limit is around 2gb approximately.
    I need to play 4 to 8 HD video files or live camera graphs. Which is not possible by a single 32 bit application.
    So I would like to play each graph in separate 32 bit application and access those video frames from my main application. In this case I could manage my need.

    Could some experts give me some clue to do this if c++ ?

    Is there any ready solution to achieve this ?

  • Get access to SDL texture pixels

    29 mai 2024, par chugadie

    Is there anyway (besides the documented slow method) to get access to the texture pixels from an SDL2 texture ? SDL_RenderReadPixels says Warning : this is a very slow method and should not be used frequently.

    &#xA;

    I want to point an ffmpeg AVFrame->data over to the texture pixels and have it encode what's in the texture. Basically, screen grab a texture after rendering and blending several textures together.

    &#xA;

    SDL_LockTexture() gives write-only access to the pixels. The docs also say not to expect pixel data to be present in the pointer returned to you.

    &#xA;

    Is it possible with av_hwframe_map in ffmpeg ?

    &#xA;

    I see lots of examples of decoding video to a texture, but I want to screen grab and encode an SDL2 texture without copying GPU data back to CPU memory.

    &#xA;

    If this is not possible in SDL2, I'm open to switching to SDL3, raylib, opengl or nearly anything else. After researching this for a few days, I'm getting the sense that OpenGL and/or Metal are the interop frameworks I should be looking at. Am I looking in the completely wrong direction trying to get SDL2/3 to allow me to interop with texture pixel data ?

    &#xA;
