• ffmpeg sRGB jpgs to rec709 mov

  9 mars 2021, par maxdownunder

  I'm trying to convert an sRGB jpeg sequence into a rec709 DnX Quicktime... but struggle to get the colormatrix right.

  


  ffmpeg -y -f image2 -start_number 1 -framerate 24 -i input.%04d.jpg -c:v dnxhd -vf "scale=1920:1080,fps=24,format=yuv422p10,colorspace=all=bt709:itrc=srgb" -b:v 175M -c:a pcm_s16le output.mov


  


  My understanding is this should set everything to rec709, but override the input response curve (itrc=srgb), but this fails with

  


  Unsupported input primaries 2 (unknown)
Error while filtering: Invalid argument
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0


  


  I haven't been able to come up with any combination of flags that doesn't trough an error and produces the right colors.

  


  Some docs here : ffmpeg filters trc

  


  Any help much appreciated !

• FFMPEG recode clip1 to match clip2 for concat demux

  21 novembre 2020, par Gert Gottschalk

  I want to concat two video clips using ffmpeg concat. To use concat demuxer both should have same codec settings. clip2 is much shorter so I want to recode it to match clip1. Initially clip2 had tbn not matching and I adjusted that with '-video_track_timescale 50000'. Still the concat video after the cut into clip2 is garbled (audio seems OK)

  


  This is what ffprobe tells for clip1 :

  Then for concat :

  


  /home/tools/bin/ffmpeg -f concat -i list.files  -y clip12.mp4


  


  The only gap is with
clip1 : 2080 kb/s
clip2 : 1553 kb/s

  


  Is that significant ?

  


  If yes, how to recode clip2 to match and result in concat clip12 being clean ?

  


  EDIT (Per feedback from llogan) :

  


  Probing input clips with latest ffprobe.

  I'm observing mismatch in what I assume is the audio channel.

    Stream #0:1(und): Audio: mp3 (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 192 kb/s (default)


  


  Probably need to match audio channel. I noticed that the concat too a long time. I was expecting the concat to just do copying and not re-rendering.

  


• How to fix the problem I'm having with FFmpeg ?

  23 février 2023, par John

  I'm working with the ffmpeg library to convert mp4 video files to mp3 audio files.
Here is my code :

  


  package com.exer;


import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.Environment;
import android.widget.Toast;
import com.github.hiteshsondhi88.libffmpeg.ExecuteBinaryResponseHandler;
import com.github.hiteshsondhi88.libffmpeg.FFmpeg;
import com.github.hiteshsondhi88.libffmpeg.FFmpegLoadBinaryResponseHandler;

public class MainActivity extends Activity {
    
    FFmpeg ffmpeg;
    private ProgressDialog progressDialog;
    
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    
        
        
        try {
            setUp();
            String[] command = {
                "-i", getPaths()+"/dir/input.mp4", "-vn", getPaths()+"/dir/output.mp3"
            };
            //convert("ffmpeg -i input.mp4 -vn output.mp3");
            convert(command);
            
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(), e.getCause().toString(), Toast.LENGTH_SHORT).show();
        }
    }
    
    
    public void setUp() throws Exception {
        
        if(ffmpeg == null) {
            
            ffmpeg = FFmpeg.getInstance(this);
            ffmpeg.loadBinary(new FFmpegLoadBinaryResponseHandler(){
                    
            @Override
            public void onFailure() {
                Toast.makeText(getApplicationContext(), "failed to load library", Toast.LENGTH_SHORT).show();   
            }
                    
            @Override
            public void onSuccess() {
                Toast.makeText(getApplicationContext(), "loaded!", Toast.LENGTH_SHORT).show();
            }
                    
            @Override
            public void onStart() {
                        
            }
                    
            @Override
            public void onFinish() {
                        
            }
                    
                    
            });
            
        }
        
    }
    
    
    private void convert(String[] cmd) throws Exception {
        
        ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler(){
            
            @Override
            public void onFailure(String message){
                super.onFailure(message);
            }
            
            @Override
            public void onFinish(){
                super.onFinish();
                Toast.makeText(getApplicationContext(), "finished!", Toast.LENGTH_SHORT).show();
            }
            
            @Override
            public void onStart(){
                super.onStart();
                Toast.makeText(getApplicationContext(), "start conversion...", Toast.LENGTH_SHORT).show();
            }
            
            @Override
            public void onProgress(String message){
                super.onProgress(message);
            }
        });
        
    
    }
    
    private String getPaths() {
        return Environment.getExternalStorageDirectory().getPath();
    }
    
}


  


  When I run the app, the Toast messages are shown :

  


  loaded!
start converting...
finished! as I write them in the functions, apart that nothing else happens the file is not converted what's wrong ?

  


  Here my manifest file :

  


  &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<manifest package="com.exer">&#xA;    &#xA;    &#xA;    &#xA;    &#xA;    &#xA;        &#xA;            &#xA;                <action></action>&#xA;&#xA;                <category></category>&#xA;            &#xA;        &#xA;    &#xA;&#xA;</manifest>&#xA;

  


  I've tried to delete the specified file on the phone to see what erros I might got, but still those three Toasts.
