FFMPEG copy audio from input to output
21 décembre 2017, par Ewan SouI'm using the below ffmpeg code to embed a video over a background image
ffmpeg -loop 1 -i -i - filter_complex "[1]scale=515:386 [vid]; [0][vid]overlay=43:46:shortest=1[out]" -map "[out]" -yThis will put my input video file on top of my input background image and create a final output video file. However, I need the audio from the input video file to be copied over to the output video file as well. How do I achieve that?
Thank you!

Concatenating video using FFMPEG wrapper class [duplicate]
21 décembre 2017, par alan samuelThis question already has an answer here:
I am trying to concatenate video using NReco.VideoConverter wrapper class made for FFMPEG.
I have three video files with the same frame rate and same frame size.
Here is what I have done.
string toconcatfile = @"C:\Users\Alan\Desktop\Black.mp4"; string output1 = @"C:\Users\Alan\Desktop\output1.mp4"; string output2 = @"C:\Users\Alan\Desktop\output2.mp4"; string finaloutput = @"C:\Users\Alan\Desktop\finaloutput.mp4";All the three videos have a frame rate of 25 and Video frame size yet it fails when I add in toconcatfile to the final conversion method.
It works when its just output1 and output2 meaning there must be a different setting in toconcatfile.
Here is what I have tried.
FFMpegConverter fFMpeg = new FFMpegConverter(); //Slices first video ConvertSettings settings = new ConvertSettings { VideoFrameRate = 25, VideoFrameSize = FrameSize.hd480, MaxDuration = startcut, AudioSampleRate = 44100 }; //Slices second video ConvertSettings settings2 = new ConvertSettings { VideoFrameRate = 25, VideoFrameSize = FrameSize.hd480, Seek = endcut, AudioSampleRate = 44100 }; //Copies framerate and size from the previous video to the concatenation video ConvertSettings settings3 = new ConvertSettings { VideoFrameRate = 25, VideoFrameSize = FrameSize.hd480, MaxDuration = 4, AppendSilentAudioStream = true, AudioSampleRate = 44100 }; string newblack = @"C:\Users\Alan\Desktop\newblack.mp4"; //Slice method called fFMpeg.ConvertMedia(pathtofile, Format.mp4, output1, Format.mp4, settings); fFMpeg.ConvertMedia(pathtofile, Format.mp4, output2, Format.mp4, settings2); fFMpeg.ConvertMedia(toconcatfile, Format.mp4, newblack, Format.mp4, settings3); String[] inputfiles = new String[2]; inputfiles[0] = output1; inputfiles[1] = newblack; //inputfiles[1] = output2; ConcatSettings concatSettings = new ConcatSettings { //CustomOutputArgs = output1+" "+ toconcatfile+ " "+output2+ " -filter_complex \"[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]\" -map \"[outv]\" - map \"[outa]\"" }; fFMpeg.ConcatMedia(inputfiles, finaloutput, Format.mp4, concatSettings);Can anyone help ?
Edit : I get the exception message - "Invalid argument (exit code: 1)",

How to speed up audio and video in FFmpeg
21 décembre 2017, par alan samuelI am trying to speed up audio and video to 4 times using a C# wrapper class for ffmpeg.
Here is how it looks.
var ffMpeg = new NReco.VideoConverter.FFMpegConverter(); ConvertSettings convertSettings = new ConvertSettings { CustomOutputArgs = "-filter_complex \"[0:v]setpts = 0.25 * PTS[v];[0:a] atempo=2.0[a],atempo=2.0[a] \" -map \"[v]\" -map \"[a]\"" }; string inputpath = tempvideolocation + "/tempvideo.mp4"; string outputpath = tempvideolocation + "/convertedvideo.mp4"; ffMpeg.ConvertMedia(inputpath, Format.mp4, outputpath, Format.mp4, convertSettings);But i get "Error - Cannot find a matching stream for unlabeled input pad 0 on filter Parsed_atempo_2 (exit code: 1)"

FFMPEG command from Python 3.5 does not actually create audio file
20 décembre 2017, par Nathan BlaineI have a Django web application that accepts user uploaded videos/audio and saves them into a folder '../WebAppDirectory/media/recordings'.
I am then using a speech to text API to get a rough transcription of the audio. This is working fine for .wav and .mp4 files, but the web app also accepts videos (.MOV) that I would like to first convert to .wav, then pass off to the API.
Using ffmpeg from my command line like this
ffmpeg -i C:\Users\Nathan\Desktop\MeetingRecorderWebAPP\media\recordings\upload_sample.MOV -ab 160k -ac 2 -ar 44100 -vn upload_sample.wavCorrectly creates the .wav file from the original .MOV.
However, when I run this from python with
subprocess.check_call(command, shell=True)ffmpeg responds with
File 'upload_sample.wav' already exists. Overwrite ? [y/N]
While Python tells me
FileNotFoundError: [Errno 2] No such file or directory: 'C:\Users\Nathan\Desktop\MeetingRecorderWebAPP\media\recordings\upload_sample.wav'
It is also worth noting that I do not see a 'upload_sample.wav' file in the media/recordings/ directory.
This leads me to believe that maybe Python and ffmpeg are looking in different folders, but I am not sure where I am going wrong. When I print the command from the subprocess.check_call and copy/paste it into cmd, the file is created as expected.
Hoping someone with some experience with ffmpeg/Python subprocess can help shed some light! Here are the files I am working with:
