  • When NVIDIA GPU is used for H265 video decoding acceleration, the video screen may skip forward frames, while AMD GPU does not [closed]

    16 août 2023, par uproar

    We are using NVIDIA GPUs (model : GTX1050TI) to accelerate H.265 video decoding and rendering, and DXVA2 hardware acceleration is used. The version of FFmpeg is 4.2.2.
If the video is played for a long time, there will be frame skipping forward (that is, the video frame of the first few seconds will appear when it is played in normal order), and it will always exist after it appears, and it will not heal itself.
Has anyone been in the same situation or can anyone help ?

    


    We checked the rendering and playback timing of each frame and found that no forward jump occurred. Therefore, the data decoded by the GPU may be incorrect.
We also used AMD GPUs for comparison tests, but this is not the case with AMD GPUs.

    


  • FFMPEG Overlay video on top of another video

    19 mai 2014, par James Blackbj Blackburn

    I have looked through all the questions on this on stackoverflow but none of the answers worked for me.

    I have a screen recorded video in mp4 and another video recorded from a webcam in mp4. I want to overlay the webcam video over the top left of the screen recorded video.

    I think I finally found the right command line for doing this but when I step through the ffmpeg process it freezes when it reaches " handler_name :SoundHandler".

    Here is my command line :

    string overlayPosition = "movie=" + '"' + _videoFile.FileName + '"' + "[inner]; [in][inner] overlay [out]";
    
string overLayCommand = "-i " + '"' + videoList[0].Path + '"' + " -vf " + '"' + overlayPosition + '"' +  + '"' + " C:\\Users\\james\\output.mp4" + '"';

    Does anyone know what I am doing wrong ? I’ve managed to trim audio and video, crop video, join sound, join video, and join sound and video but cannot get overlay to work :(.
