• TimeSpan in Aforge.Net, set time for each image in a video

  23 décembre 2020, par Siddhant Singh

  I have a query I am creating a video from the set of images using the Aforge.net framework but the video is playing very fast I want at least 5 seconds for each image in the video, I have tried using timeSpan but I didn’t get the desired result.
could anyone please suggest me or help me to find out my solution.

  


  here is my code

  


  TimeSpan timeSpan = new TimeSpan(0, 0, 5);
string[] paths = Directory.GetFiles(basePaths);
int imagesCount = paths.Length;
using (var vFWriter = new VideoFileWriter())
{

vFWriter.Open(@”D:\videosss.avi”, 1920, 1080,1,VideoCodec.MPEG4,4000000);

for (int i = 0; i < imagesCount; i++)
{
var imagePath = string.Format(paths[i]);
using (Bitmap image = Bitmap.FromFile(imagePath) as Bitmap)
{
vFWriter.WriteVideoFrame(image,timeSpan);

}

}
}
}


  


  if I use timespan the first image plays the whole time of timespan, if I don't use timespan the video plays well but fast. the directory contains 15 images I want 5 or 6 sec at least for each image in the video. where the 45 sec is my total time.

  


  thanks

  


• How to get specific start & end time in ffmpeg by Node JS ?

  3 novembre 2017, par Santosh Suryawanshi

  I want to cut a video in specific start & end time & save it. I cant understand how to cut specific time of that video by Node JS.

  Video copy code :

   return new Promise(function(resolve ,reject){
  
          var ffmpeg = require('fluent-ffmpeg');
  
          ffmpeg(fs.createReadStream(path.join(__dirname,'..','..','/video.mp4')))
  
              .seekInput('01:00')
  
              .duration('02:00')
  
              .outputOptions('-strict experimental')
  
              .on('start', function(commandLine) {
  
                  console.log('Spawned Ffmpeg with command: ' + commandLine);
  
                  }).on('end', function(err) {
  
                  if (!err) {
  
                      console.log('conversion Done');
  
                      //res.send("conversion Done");
  
                      resolve();
  
                  }
  
                  }).on('error', function(err) {
  
                      console.log('error: ', +err);
  
                      reject(err);
  
                  }).save(path.join(__dirname,'..','..','/test.mp4'));
  
      });

• Random time and positioning of a watermark FFmpeg

  5 mai 2020, par necakaranfil

  How can i restrict this code just to show the watermark on the Top,bottom:Left/right position in a random sequence. And how can i change the time interval when the logo pops up to random ? Or if anyone has a better one, that can do this, that could be useful to.

  



  for %%a in ("*.mp4") do ffmpeg -i "%%a" -loop 1 -i logo.png -filter_complex "[1]trim=0:30,fade=in:st=0:d=1:alpha=1,fade=out:st=9:d=1:alpha=1,loop=999:750:0,setpts=N/25/TB[w];[0][w]overlay=shortest=1:x=if(eq(mod(n\,200)\,0)\,sin(random(1))*W\,x):y=if(eq(mod(n\,200)\,0)\,sin(random(1))*H\,y)" "1%%~na.mp4"

  



  Thanks
