Why when creating a video file from images using ffmpeg when playing the video file the quality is bad and the video is running too fast ?
27 avril 2016, par Daniel Voitpublic void Start(string pathFileName, int BitmapRate)
{
try
{
string outPath = pathFileName;
p = new NamedPipeServerStream(pipename, PipeDirection.Out, 1, PipeTransmissionMode.Byte);
ProcessStartInfo psi = new ProcessStartInfo();
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.UseShellExecute = false;
psi.CreateNoWindow = false;
psi.FileName = ffmpegFileName;
psi.WorkingDirectory = workingDirectory;
psi.Arguments = @"-f rawvideo -pix_fmt bgra -video_size 1920x1080 -i \\.\pipe\mytestpipe -c:v libx264 -crf 20 -r " + BitmapRate + " " + outPath;
//@"-f rawvideo -pix_fmt bgra -video_size 1920x1080 -i \\.\pipe\mytestpipe -c:v mpeg2video -crf 20 -r " + BitmapRate + " " + outPath;
process = Process.Start(psi);
process.EnableRaisingEvents = false;
psi.RedirectStandardError = true;
p.WaitForConnection();
}
catch (Exception err)
{
Logger.Write("Exception Error: " + err.ToString());
}
}I tried to use either the first or second line.
BitmapRate is set to 25
I tried to change both 20 to 10 and also the BitmapRate to 10 or to 17. but the video on hard disk when playing it it’s only 3-4 seconds bad quality.
I see all the images but too fast it’s like running I forward mode.Each file size is 8MB on hard disk.
55 Bitmap files.
The video file is 1072 KBTried to google but I didn’t find any googd example to fix it.
It’s not that it’s not creating the video file it does but with bad quality and running too fast.It’s strange why the created video file is so small if every file is 8MB and why so bad quality.

Video Comparison Using Java - Video similarity [on hold]
23 novembre 2013, par Emily WebbIs there approach to compare 2 videos and check are they different versions of the same video...
Here by different version I meant that we can create two same videos with different resolutions or one of the video can be a large video and the other one can be a portion of it.But we should recognize both videos as same video in this scenario.
Is there any java libraries to attain this ? Or is there any approaches to achieve this ?
