  • Is it possible to use nvidia hardware to decode videos in opencv ?

    1er janvier 2016, par Mickey Shine

    I am using opencv 3.1 and try to deal with some video files and also streaming videos (rtps ://..). I installed vdpau and compiled ffmpeg 2.8.4 with vdpau enabled. But opencv seems still not using hardware to deocde videos. I don’t use GPU for video output but the integrated graphics.

    [root@localhost ~]# nvidia-smi dmon
    
# gpu   pwr  temp    sm   mem   enc   dec  mclk  pclk
    
# Idx     W     C     %     %     %     %   MHz   MHz
    
    0    72    49     0     0     0     0  3505  1001

    The ’dec’ were always 0. So any advices ?

  • Trying to add intro on big amount of videos

    26 novembre 2019, par somerandomdude

    first time asking a question here so sorry if im not doing it right.

    so i’ve got lots of videos on different folders. im trying to add an intro and a watermark on them all
    watermark should be added to the video and then the intro should be added after.
    i tried ffmpeg on a video it worked but the video is so damn slow like x.25 or something

    im trying to write a batch script that does the whole thing on all folders.
    some of them are like :
    folder/video.mp4
    folder/subfolder/subfolder/video.mp4

    i don’t know how to deal with those and im talking like 6k videos.

    again sorry if im not doing it right.
    i tried something like this : in batch.

    (for %%i in (*.mp4) do @echo file '%%i') > ./list.txt
    
ffmpeg -f concat -i ./list.txt -c copy ./output.mp4
    
PAUSE

  • Remove watermark by merging two videos

    29 septembre 2019, par LoStack

    I have actually two videos, one in high quality but with watermark and the other in poor quality without watermark. They are not synchronized.

    I would like to do something like the removelogo filter of ffmpeg but instead to simply interpolate like removelogo I would like to extract a part of a frame of the poor quality video to put it on the highest quality video with a mask to hide the watermark.

    Unfortunately the two videos are not synchronized and I would like to synchronize with the audio stream.

    Is it possible to do that with ffmpeg ?
    Thank you very much.
