  • FFMPEG + SDL : How To Show Multi Frames In Separate Region ?

    19 mai 2014, par user3051473

    I’m using ffmpeg and SDL to develop an camera monitor APP and I want to show four separate streams at the same time(via four rtsp source). As following figure out :

    Now I achieve this by setting the SDL display region, and I identify different display region by using the different SDL_Rect identifying by the variable i(from 1 - 4).

    But this cause the efficient problem. For every region, I need to scale to the whole screen and lock/unlock screen, then display.

    I’m wondering that, Can I merge 4 different AVFrame(come from REG1 - REG4) into the whole picture and then show this picture ?

    Hope that the describe about is detail enough for you to konw my problem.
    Also thanks for your help.
