So I have a bunch of images in a folder, with the following structure:
image-0.png
image-1.png
image-2.png
Sometimes the folder can have just 1 image which will be saved as:
image-0.png
My code to generate the video and to add the audio
// create the file
using (WaveFileReader wf = new WaveFileReader(Audio))
{
// the files
OldVideo = "old.avi";
NewVideo = "video.avi";
Audio = "sound.wav";
// Get the time of the audio and divide by images
time = wf.TotalTime.TotalSeconds;
mimtime = time / imagescount;
ffmpegPath = "ffmpeg.exe";
ffmpegParams = " -r 1/" + mimtime + " -i " + ImagesFolder + "image-%d.png -t " + time + " -y -vf scale=1280:-2 " + OldVideo;
ffmaudioParams = " -i " + OldVideo + " -i " + Audio + " -c copy -shortest " + NewVideo;
}
using (Process ffmpeg = new Process())
{
//Generate video
ffmpegstartInfo = new ProcessStartInfo();
ffmpegstartInfo.FileName = ffmpegPath;
ffmpegstartInfo.Arguments = ffmpegParams;
ffmpegstartInfo.RedirectStandardOutput = true;
ffmpegstartInfo.RedirectStandardError = true;
ffmpegstartInfo.UseShellExecute = false;
ffmpegstartInfo.CreateNoWindow = true;
ffmpeg.StartInfo.FileName = ffmpegPath;
ffmpeg.StartInfo.Arguments = ffmpegParams;
ffmpeg.StartInfo = ffmpegstartInfo;
ffmpeg.Start();
ffmpeg.WaitForExit(30000);
/*ffmpeg.StartInfo.FileName = "cmd.exe";
ffmpeg.StartInfo.Arguments = "/k " + ffmpegPath + " " + ffmpegParams;
ffmpeg.Start();
ffmpeg.WaitForExit(30000);*/
}
using (Process ffmaudio = new Process())
{
//Add audio to video
ffmaudiostartInfo = new ProcessStartInfo();
ffmaudiostartInfo.FileName = ffmpegPath;
ffmaudiostartInfo.Arguments = ffmaudioParams;
ffmaudiostartInfo.RedirectStandardOutput = true;
ffmaudiostartInfo.RedirectStandardError = true;
ffmaudiostartInfo.UseShellExecute = false;
ffmaudiostartInfo.CreateNoWindow = true;
ffmaudio.StartInfo.FileName = ffmpegPath;
ffmaudio.StartInfo.Arguments = ffmaudioParams;
ffmaudio.StartInfo = ffmaudiostartInfo;
ffmaudio.Start();
ffmaudio.WaitForExit(30000);
/*ffmaudio.StartInfo.FileName = "cmd.exe";
ffmaudio.StartInfo.Arguments = "/k " + ffmpegPath + " " + ffmaudioParams;
ffmaudio.Start();
ffmaudio.WaitForExit(30000);*/
}
So, what my code does, with the wavfilereader it gets the total length of my audio file, and then splits that time up by the number of images I have, so I can generate a video with the images split equally. Then I generate the video to a file called 'old.avi', which is then used with my wav file to generate a new file called video.avi (which I am trying to have the generated video and audio together)
My problem is when I generate the video it becomes uplayable. It claims to be (for example) 1 minute 50 seconds long, but once I click it, it won't play. It just becomes unplayable, as you can see below

I am using C# with process and Winforms, which opens the cmd line to run ffmpeg, with the 2 commands called above with the named variables below:
ffmpegParams;
ffmaudioParams;
Which has all the commands I am using
-r 1/ (audio length /divided by total images) so they're equal
-t (to limit to the total time which is the audio's total seconds)
... I am using more as you can see in my code above
How can I fix my problem, that I have described?
