  • sdl 1.2 & ffmpeg 1.09 flickering when overlays a picture during a video is playing

    29 septembre 2014, par Alberto Martín

    Iḿ developing a media player using SDL1.2 & ffmpeg 1.09.(C programming over VS2010, win7)

    I have flickering when i try to overlay an image in the screen during the video is playing.(Like full screen buttons or an ad).

    To display the video i’m creating overlay using SDL_CreateYUVoverlay function. Then I set the rectangle and call SDL_DisplayYUVOverlay.

    I’m trying to show a picture while the video is playing.
    For showing the picture i tried YUV overlays(SDL_CreateYUVoverlay + SDL_DisplayYUVOverlay ) and also with surfaces(SDL_BlitSurface + SDL_UpdateRect or SDL_Flip) but it always flickers.

    I use ffplay.c as an example.

    I read something about merge two YUV overlays in one (2 input to 1 output), but i could not found information or examples about that.

    Does anyone knows how to do this ?

  • Files of ffmpeg after installation on mac

    31 janvier 2018, par Hélder

    While reading this post on motion vector on SO, I went to my mac system files and tried to find the vf_codecview.c and frame.c files but without success.

    Does anyone know where they are located after we install ffmpeg ?

  • How to change the size of audio visualisers in ffmpeg ?

    3 juillet 2017, par Meme Stream

    I have this command in ffmpeg :

    echo shell_exec("$ffmpeg  -i test.aiff -y -filter_complex '[0:a]showfreqs=s=1920x1080:mode=bar:ascale=log:fscale=lin:win_size=w1024:win_func=poisson:colors=blue,format=yuv420p[v]' -map '[v]' -map 0:a output2.mp4 2>&1");

    I want to make it so that the video dimensions are still 1080p but the showfreqs graph is squashed and located near the bottom of the screen. How do I do this ? Thanks.
