Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

Stream PNG file to youtube with ffmpeg
3 avril 2022, par codingmaster398What I'm trying to do :
I have a PNG file that is constantly getting written to. I want to pipe it (while it changes) to YouTube's RTMP server.


What I've attempted :


runCommand(
 'ffmpeg',
 `-threads:v 2 -threads:a 8 -filter_threads 2 -thread_queue_size 512 \
-loop 1 -re -i place.png \
-stream_loop -1 \
-filter:v "crop=in_w/2:in_h/2:1920:1280" \
-pix_fmt yuv420p -c:v libx264 -qp:v 19 -profile:v high -rc:v cbr_ld_hq -level:v 4.2 -r:v 60 -g:v 120 -bf:v 3 -refs:v 16 -preset fast -f flv rtmp://a.rtmp.youtube.com/live2/${steamKey}`,
 () => {},
 () => console.log('finished')
)

setInterval(()=>{
 image.write('./place.png') // Jimp },5000)



What happens :

FFMPEG on MACOSX is complaining "no matches found"
15 juin 2022, par Byte PlayerI have a FFMPEG command line function that works perfectly on Windows but on Mac produces the following error :


"no matches found [1:a]adelay=15000:all=1[aud2]"

"no matches found [2:a]adelay=5000:all=1[aud3]"

Here is the command (less the full paths which just made it very hard to read). I've verified that the files exist at the paths specified by copying the file path from the command line and going into terminal, typing "open" then pasting in the copied path and pressing enter. In all cases they played.


ffmpeg -loglevel warning -hide_banner -y -i "file1.mp3" -t 5 -i "file2.mp3" -i "file3.mp3" -i "file4.mp3" -ss 25 -t 15 -i "file5.mp3" -ss 15 -t 5 -i "file6.mp3" -filter_complex [1:a]adelay=15000:all=1[aud1];[2:a]adelay=5000:all=1[aud2];[4:a]adelay=25000:all=1[aud4];[5:a]adelay=5000:all=1[aud5];[aud1][aud2][aud4][aud5]amix=inputs=6:duration=longest:dropout_transition=0:normalize=0 "output.mp3"



I know the immediate response (as it should be), is update your FFMPEG but I got the latest build (built on 2022-06-12) and here's what it reports...

How to manipulate files by ffmpeg in Android 31 : permission denied
17 septembre 2021, par Omid.NI am trying to use FFmpeg in my android app. So I want to test it if it works before moving on. I use an external library : github link

The code looks like this :

package net.omidn.aslanmediaconverter;

import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

import com.arthenica.ffmpegkit.ExecuteCallback;
import com.arthenica.ffmpegkit.FFmpegKit;
import com.arthenica.ffmpegkit.FFmpegSession;
import com.arthenica.ffmpegkit.Session;

import net.bramp.ffmpeg.job.FFmpegJob;

import java.io.BufferedInputStream;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;


public class MainActivity extends AppCompatActivity {
 
 private static final String TAG = "MainActivity";
 FFmpegJob myjob;

 @Override
 protected void onCreate(Bundle savedInstanceState) {


 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 TextView textView = (TextView) findViewById(R.id.text_view);


 FFmpegJob job = null;

 File inFile = new File("/storage/emulated/0/video_2021-05-29_17-50-20.mp4");
 String inputName = Uri.fromFile(inFile).toString();
 Log.d(TAG, inputName);
 Log.d(TAG,"file exists : " + String.valueOf(inFile.exists()));
 Log.d(TAG,"file canRead : " + String.valueOf(inFile.canRead()));

 FFmpegSession fFmpegSession = FFmpegKit.executeAsync("-i file:///storage/emulated/0/video_2021-05-29_17-50-20.mp4 -c:v mpeg4 file:///storage/emulated/0/out.mp4",
 new ExecuteCallback() {
 @Override
 public void apply(Session session) {

 }
 });
 try {
 Thread.sleep(5000);
 } catch (InterruptedException e) {
 e.printStackTrace();
 }
 textView.setText("" + fFmpegSession.getState().name() + " " + fFmpegSession.getOutput());
 }

}




As you can see I give the files with
file:///
protocol. If I don't use that the resault is the same. The three lines ofLog.d(...)
will print :

2021-06-03 00:58:08.869 8376-8376/net.omidn.aslanmediaconverter D/MainActivity: file:///storage/emulated/0/video_2021-05-29_17-50-20.mp4
2021-06-03 00:58:08.869 8376-8376/net.omidn.aslanmediaconverter D/MainActivity: file exists : true
2021-06-03 00:58:08.869 8376-8376/net.omidn.aslanmediaconverter D/MainActivity: file canRead : false



The video file has read access on the storage :
