  • ffmpeg for android out of memory

    15 juin 2018, par Rafael Lima

    I’m getting an weird error when enconding a video with ffmpeg on android

    Failed to inject frame into filter network: Out of memory

    Althoug is a pretty objective error, I do believe this is some "generic message" for another problem, because the video I used for testing is 17MB and less than 11 seconds length and I’ve sucessfully tested with videos bigger than 200MB and longer than 5min

    This problem happens to any video recorded on my phone (the videos were recorded and play fine on my phone but i cant reencode them... other video h264 were encoded fine on same phone)

    this is ffmpeg output

  • Compile the GPU version of FFMPEG to OpenCV

    12 juillet 2018, par Dyex719

    When I try to use GPU
    FFMPEG on opencv by using a command like :

    VideoCapture cap("rtsp link");
    

    
for(;;)
    
{
    
mat frame;
    
cap>>frame;
    
}

    I don’t see any output on nvidia-smi despite compiling the GPU version of FFMPEG.

    I am trying to get FFMPEG to use GPU to improve the speed of my program. I got FFMPEG from cloning this and followed the steps here to get it working.

    I have validated the results using nvidia-smi dmon -i 0 and have seen that dec% increases when I run the command ffmpeg -c:v h264_cuvid -i test_video.mp4 test_output.mkv.

    I then compiled Opencv to use the GPU enabled FFMPEG, I check this by running getBuildInformation from opencv :

    Video I/O: 
    
DC1394 1.x: NO 
    
DC1394 2.x: YES (ver 2.2.4)

    I cross-verify that I’m using the same ffmpeg (by checking the version numbers) :

    Please advise me on how I should compile OpenCV to use the GPU version of FFMPEG. Thank you !
