ffmpeg export without color loss
27 décembre 2020, par serI'm trying to add a watermark to a video through ffmpeg, but all the exports result in loss of color information. I would like to retain the same color information as the original video, how do I do that ?


Currently, I use this code :


./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "



I realised the only way to not lose the color information is to set -crf to 0 and -preset to veryslow, but it results in a really large file size. (2 times the size of original video, which is not effective)


I also get this error when I run ffpmeg :


[swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly



See Image comparison here — the blacks on the export were not as "black" as original

c# how to correctly format an ffmpeg user input stream ?
6 janvier 2021, par user14527374So I'm writing a c# application which allows a user to scale a video in pixels to a custom dimension. I am strugeling to get the user input from a textbox for the mpeg psi arguments :


Here is the code :


var localStoragePath = Path.Combine(Path.GetTempPath(), name);
 var directoryPath = Path.GetDirectoryName(localStoragePath);
 Directory.CreateDirectory(directoryPath);
 File.WriteAllBytes(localStoragePath, bytes);
 Progress.Text = ($"File copy successful: {File.Exists(localStoragePath)}");
 var readBack = File.ReadAllBytes(localStoragePath);
 Progress.Text = ($"Read file Back: {readBack.Length}, {localStoragePath}");
 var resizedFolderPath = @"C:\upscaledvideohere";
 Directory.CreateDirectory(resizedFolderPath);
 var resizedFiePath = Path.Combine(resizedFolderPath, Path.GetFileName(localStoragePath));

 var psi = new ProcessStartInfo();
 psi.FileName = @"C:\ffmpeg-2020-12-27-git-bff6fbead8-full_build\bin\ffmpeg.exe";
 psi.Arguments = $"-i \"{localStoragePath}\" -vf scale=" + pixelsheight.Text "\"{resizedFiePath}\"";
 psi.RedirectStandardOutput = false;
 psi.RedirectStandardError = false;
 psi.UseShellExecute = true;
 Progress.Text = ($"Args: {psi.Arguments}");



For


psi.Arguments = $"-i \"{localStoragePath}\" -vf scale=" + pixelsheight.Text "\"{resizedFiePath}\""



What would be the correct way to input the text for what the user typedin the pixelsheight text box ?


Thanks very much.

Looking for a general purpose way to merge audio and video file and make an output have stereo audio with FFmpeg
21 février 2020, par Pineapple JoeSo have have the following FFmpeg command
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2,apad[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y mergeab.mp4
When the input files are played separately their audio is played equally through both headphones.
But after being merged the audio from the video is on the right side and the audio from the webm file is on the left side.
I see this in the output when I run the cmd
[Parsed_amerge_2 @ 0x7fa0faf01bc0] No channel layout for input 1
[Parsed_amerge_2 @ 0x7fa0faf01bc0] Input channel layouts overlap: output layout will be determined by the number of distinct input channelsHow can I adjust this so that the output file has the audio from both the inputs in equally in the left and right sides ?
Also is there a generic way to do this such that even different configurations (video has stereo and audio has mono ... or both have stereo) result in the Audio being split evenly.
I tried using the pan filter but there is something I am not understanding about how it works because either nothing happens or I flip left and right. But I am not getting even stereo.
fwiw here is the full output.
ffmpeg -i vidab.mp4 -i recab.webm -filter_complex "[0:a]volume=0.2,apad[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y mergeab.mp4
