  • Best library for video rendering [on hold]

    19 avril 2015, par galbarm

    I’m trying to rewrite the video rendering component in my application from scratch.

    Currently, it is using Direct3D of the the old managed DirectX 9.

    The video is originating from IP cameras and is being decoded using FFmpeg.

    The video is currently being be displayed within a UserControl inside the application. This is not supposed to change.

    Which libary should I choose to use for the rendering of the video ?

    Additional points :

    1. it is preferred that the rendering library will be .NET, but c++ is also optional.

    2. It should be optimized for displaying multiple videos simultaneously.
      This point is important. The application needs to display as many videos as possible from different IP cameras.

    3. It should be optimized for displaying camera video (it is not gaming video so that’s why I’m not sure DirectX is the natural option).

    4. It should support 64bit. Windows only.

    5. Bonus : it should integrate with FFmpeg in some way, to reduce development effort and maybe even increase performance.

  • I ues FFMPEG to convert bitmap to yuv,and try to save it,but failed

    20 avril 2013, par liaoyuandeyehuo

    I use this way to convert bitmap to yuv
    Save bitmap to video (libavcodec ffmpeg)
    and then save the buffer like this :

    FILE* fp=fopen("aha.yuv","w");
    
if(!fp) return NULL;
    
fwrite(outPic->data[0],nbytes,1,fp);
    
fwrite(outBuffer,nbytes,1,fp);
    
fclose(fp);

    but it has only several lines. All most all of the .yuv file is gray.
    I am sure the inbuffer points to the input BGR32 data. So where is wrong ?
    Is The way to save the outBuffer right ?
