  • Convert video to hequirect while setting the background black and blur the transitional area [closed]

    11 février 2024, par Zurechtweiser

    I am using

    


    ffmpeg -i input.mp4 -vf "v360=input=fisheye:ih_fov=122.6:iv_fov=94.4:output=hequirect:h_fov=180:v_fov=180:in_stereo=2d:out_stereo=sbs,format=yuv420p" -b:v 25M -maxrate 60M -bufsize 25M output.mp4


    


    Which works as advertised to convert a fisheye to hequirect except for two problems :

    


      


    1. The background is not black but seems to try and set it to the average color of the video. It should be black throughout.

      


      2. 


    2. The corners are not blurred but should be, there should be a soft transition from the corner of the video into black.

      


      3. 


    


  • Can't Titan Black use NVENC ?

    13 mars 2016, par SPWW

    I compiled FFMPEG with —enable-nvenc and want to encode with NVENC encoder, but I got this error message when running ffmpeg.

    [nvenc_h264 @ 0x8ed020] 4 CUDA capable devices found
    
[nvenc_h264 @ 0x8ed020] [ GPU #0 - < GeForce GTX TITAN Black > has Compute SM 3.5, NVENC Not Available ]

    I have titan black gpu and as the official document said it should be supported.

    my nvenc-sdk version is 5.0

    and the nvidia-smi info is listed below.

  • Remove Black Frames from an overlayed Circled Video

    7 juillet 2017, par amanguel

    I have a video that I need to overlay on top of another video. The first video have parts with black frames that I don’t want to be overlayed and I also need to mask this video with a circle.

    In other words, I will be overlaying a few circled videos on top of a bigger rectangular video and I also don’t want to show black frames from the circled videos.

    Could you please help me.

    Thanks !!!!!
