  • FFMPEG : how to create a "title slide" for 3 seconds before a video [closed]

    15 mars 2024, par ashay

    I'm trying to make a lecture video to put online. I have the video itself, and I have a title slide that I'd like to play for 3 seconds before the main video.

    


    I tried using ffmpeg to (1) create a 3 second long video from the title slide and (2) concat the two videos together.

    


    I'm having issues concatenating the videos together — when I do so, the resulting video is much longer than it should be. When I look online, others have similar problems — and this seems to occur when the parameters of the two videos do not match perfectly.

    


    I'd prefer to do this without re-encoding the main video — and it seems this should be possible because I should be able to control what parameters are set for the "lecture slide video".

    


    Here are the commands I've run.
The main video has framerate 25, resolution 1920x1080, and an audio stream at #0:0 and a video stream at #0:1 (according to ffmpeg -i [video].

    


    To create the video of the title slide, I ran ffmpeg -framerate 25 -i lec01_title.png -t 3 -c:v libx264 -x265-params lossless=1 -pix_fmt yuvj420p -vf scale=1920:1080 lec01_title.mp4 -f lavfi -i anullsrc -c:a aac -shortest.
Then to reorder the streams to match the main video, I ran ffmpeg -i lec01_title.mp4 -map 0:a -map 0:v -c:v copy -c:a copy lec01_title_matched.mp4.

    


    Then to concatenate the two files together, I created a text file "concat_list" with :
file 'lec01_title_matched.mp4' file 'lec01.mp4', and ran the command ffmpeg -f concat -safe 0 -i concat_list.txt -c copy -movflags +faststart output.mp4.

    


    The main video is 53 minutes long, but the final output video after concatenating is 1 hour and 43 minutes long.

    


    I'm looking for advice for how to create the "lecture title video" properly to match the parameters of the second video so that I can concatenate them without problems.

    


    Here's the output of ffmpeg -i lec01.mp4 :

  • The error "Failed to query nvenc max version" typically occurs when using FFmpeg on Linux

    28 juillet 2023, par Well Chen

    The error "Failed to query nvenc max version" typically occurs when using FFmpeg with NVIDIA GPU acceleration (hevc_nvenc) on Linux.

    


    Does anyone know how to solve this bug ? Thank you very much.

    I have installed FFmpeg, NVIDIA GPU drivers, and SDK. It works fine without using GPU acceleration, but it throws an error when using GPU acceleration.

    


  • ffmpeg concat doesn't keep video speed/framerate ?

    28 août 2016, par Nick

    I have a bunch of small webm clips in directory vidchunks. These clips were generated using javascript MediaRecorder API.

    MediaRecorder code :

    var mRecorder;
    
var chunks = [];
    
navigator.mediaDevices.getUserMedia({
    
  audio: false,
    
  video: {
    
  width: 1280,
    
  height: 760,
    
  mozMediaSource: "screen",
    
  mediaSource: "screen"
    
}
    
}).then(function(stream) {
    
  mRecorder = new MediaRecorder(stream,{mimeType:"video/webm"});
    
  mRecorder.ondataavailable = function(event) {
    
    var blob = event.data;
    
    chunks.push(blob);
    
    var vidchunk = new Blob(chunks);
    
    // save to directory vid chunk.
    
  };
    
  mRecorder.start(5000);
    
}).catch(function(error) {
    
  console.log(error.message);
    
});

    Then, once I have a bunch of these 5 second clips, I merge them :

    ffmpeg -safe 0 \
    
-f concat -i <(for f in `ls vidchunks/* | sort -V`; do echo file $f; done) \
    
-c:v copy -r 30 -vsync drop test.webm

    When I play back these chunks individually, they play correctly. All 5 seconds of video are rendered smoothly.

    However, once I merge, some 5 second chunks are condensed to like 1 second. So the total video, which should be 50 seconds for 10 chunks, turns out to be like 38 seconds because three of the chunks got condensed to 1 second.

    Any ideas on how to fix this ?

    EDIT : I’ve tried :

    • without "-r 30 -vsync drop"
    • without "-c:v copy"

    No changes...

    I also noticed that the merged video plays normal when the mouse is moving around on the screen, but when the mouse is not moving, it moves 5x faster.

    I know this because I have a timer on the screen that I’m recording, and I can see that the timer speeds up significantly when mouse isn’t moving but when mouse is moving, the timer moves at normal speed.
