FFMPEG stuck at 00:00:00 speed=0x for a long time at the beginning
4 juin 2020, par lagmoellertimI'm currently writing a script that can remove silence from any video. I'm doing this using ffmpeg and a complex_filter script.



Since most of my videos are pretty long (>1.5h), ffmpeg is called multiple times with a different complex_filter, each editing a part of the video (about 8 minutes long each) and combining those parts at the end.



The input file for all these separate parts is always the original 1.5h video clip.



The problem I keep getting is that for videos starting not directly at the start (first part works fine, second part starting at minute 8 takes longer, third part starting at minute 16 even longer, ... you get the point), this shows up and gets displayed for quite a long time, until it finally works with its normal speed :



frame= 0 fps=0.0 q=0.0 size= 0kB time=00:00:00.00 bitrate=N/A speed= 0x


Here is the ffmpeg script I use



ffmpeg -i video.mp4 -vsync 1 -async 1 -safe 0 -filter_complex_script /path/to/complex_filter -y -map '[vout]' -map '[aout]' video_parts/infb4_3.mp4


I also tried adding
-ss 00:24:00before or behind the-iinput, but I did not notice any speed improvement.


And here the complex_filter of one part of the video, starting at minute 24 and ending at minute 32 :

C# FFMPEG : Code bugs out and stops producing media files
24 mai 2020, par HamezI've made a joke program in C# that uses ffmpeg to edit videos with different effects such as stuttering. I've finished 3 effects so far and each of them work on their own but as soon as I put one after another
e.g. fx.CrashStutter(0, 2); fx.CrashBeep(2, 2); fx.Wow(4, 2);
The code breaks and no longer produces photo/video files but once I stop debugging the file it was supposed to be processing appears. I've used a system where it loops over trying to execute a command to create a text file as a marker for when ffmpeg is done processing a file. The debug console also repeatedly says "The process tried to write to a nonexistent pipe."


Here's the code for all 3 effects :



public void Wow(double start, double duration)
 {
 if (fxstart == true)
 {
 //MessageBox.Show("WowFX Duration" + duration);
 string folderName = ("W_s" + start);
 System.Threading.Thread.Sleep(100);
 FXcmd.StandardInput.WriteLine("mkdir " + folderName);
 System.Threading.Thread.Sleep(100);
 FXcmd.StandardInput.WriteLine("cd " + folderName);
 System.Threading.Thread.Sleep(100);
 FXcmd.StandardInput.WriteLine("ffmpeg -ss " + start + " -t " + (duration / 6) + " -i " + source + " a.mp4");
 //wait until a.mp4 appears
 while (File.Exists("FxSource(Temporary)\\" + folderName + "\\a.txt") == false)
 {
 /*aha got a live one!*/FXcmd.StandardInput.WriteLine(" echo a > a.txt");
 System.Threading.Thread.Sleep(1500);
 }
 FXcmd.StandardInput.WriteLine("ffmpeg -i a.mp4 -vf reverse -af areverse b.mp4");
 //wait until b.mp4 appears
 while (File.Exists("FxSource(Temporary)\\" + folderName + "\\b.txt") == false)
 {
 FXcmd.StandardInput.WriteLine(" echo b > b.txt");
 System.Threading.Thread.Sleep(1500);
 }
 FXcmd.StandardInput.WriteLine("ffmpeg -ss " + start + " -t " + (duration / 3) + " -i " + source + " c.mp4");
 //wait until c.mp4 appears
 while (File.Exists("FxSource(Temporary)\\" + folderName + "\\c.txt") == false)
 {
 FXcmd.StandardInput.WriteLine(" echo c > c.txt");
 System.Threading.Thread.Sleep(1500);
 }
 FXcmd.StandardInput.WriteLine("ffmpeg -i c.mp4 -vf reverse -af areverse d.mp4");
 //wait until d.mp4 appears
 while (File.Exists("FxSource(Temporary)\\" + folderName + "\\d.txt") == false)
 {
 FXcmd.StandardInput.WriteLine(" echo d > d.txt");
 System.Threading.Thread.Sleep(1500);

 string[] concatList = { "file 'a.mp4'", "file 'b.mp4'", "file 'c.mp4'", "file 'd.mp4'" };
 //FXcmd.StandardInput.Write("del a.txt, b.txt, c.txt, d.txt");
 //System.Threading.Thread.Sleep(1000);
 System.IO.File.WriteAllLines(("FxSource(Temporary)\\" + folderName + "\\concatList.txt"), concatList);

Any suggestions ? Thanks !

Add watermark, set bitrate and scale video
15 mai 2020, par razzI'm looking for the command to edit a video with ffmpeg according to instructions below.



The original video can be any type in any size or resolution (mp4,avi,wmv etc) and needs to be converted to mp4



- 

- Convert video to .mp4
- Add a watermark at the right bottom
- Set a Bitrate (accepted values between 1500 - 2000 )
- Resize width to 1280px (keep aspect ratio)
