ffmpeg concat only continues audio, not video
23 avril 2017, par StefanI’m trying to concat 3 videos with ffmpeg. Here the code I use.
ffmpeg -f concat -safe 0 -i c:/ffmpeg/data/mylist.txt -c copy output.mp4In my first try the first video played for the set time and then nothing more happened. There I tried to sync the audio and ran the following on all videos.
ffmpeg -i c:/ffmpeg/data/intro.mp4 -af apad -c:v copy -b:a 384k -shortest -avoid_negative_ts make_zero -fflags +genpts intro.mp4After running the concat again, now the audio from all 3 files play throughout the video, but only the video from the first video shows throughout the whole video.
I’ve tried to to get the video tracks in the same encoding with the following without any changed in th concat result.
ffmpeg -i c:/ffmpeg/data/video1.mp4 -r 24 video1.mp4AND
ffmpeg -i c:/ffmpeg/data/video1.mp4 -af apad -c:v copy -b:v 64k -b:a 384k -shortest -avoid_negative_ts make_zero -fflags +genpts video1.mp4Here the ffprobe results for the 3 videos

Mix 2 mp3 files with FFmpeg for Android
24 mai 2017, par Thankgod RichardI am developing something similar to a karaoke app. I have a sound file(beat) and a recorded file(voice) from android mediarecorder. I am trying to mix the two files to become one file that plays the same time. I have set up ffmpeg provided by writingminds and everything is working fine. I am not familiar with ffmpeg commands so searched for and got few commands that can achieve the task for me. This is the code i got :
String files = "-i " + currentFile + " -i " + someFile.getAbsolutePath();
String output = mFileName + "/recorded/test.mp3";
String cmd = "ffmpeg "+files+
" -filter_complex \"aevalsrc=0:d=10[s1];[s1][1:a]concat=n=2:v=0:a=1[ac1];[0:a][ac1]amix[aout]\" -map [aout] -c:a libmp3lame " + output;But it not working. this is the error i got :

How to modify music pitch in audio of video file and still sound natural
9 janvier 2020, par Keith BennettI have some karaoke .mp4 video files (legally obtained) for Thai songs, and want to convert the pitch downward to fit my singing range. I’ve gotten most of the way there thanks to https://superuser.com/questions/292833/how-to-change-audio-frequency/1076762#1076762
using a command line like this :ffmpeg -i in.mp4 -af 'asetrate=35280.0,atempo=1.25' out.mp4...but the instruments and human singing voices don’t sound natural at the modified pitch.
Is there a better way to change the pitch ? I know some commercial products can do this.
By the way, I wrote a Ruby script to simplify this ffmpeg call ; it’s at https://gist.github.com/keithrbennett/9ba7043792bfb2fcc92d615076a8413f. It enables you to specify a single factor, and modifies both pitch and tempo accordingly.
