Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

FFmpeg record and stream
16 janvier 2019, par RobertI’m getting the following error.
E/FFmpeg: Exception while trying to run:
[/data/user/0/com.example.pathways.testipcam/files/ffmpeg, -y, -i,
rtsp://log:pass@IP:port/video.h264, -acodec, copy, -vcodec, copy, -t,
00:03:00,
content://com.example.android.fileprovider/external_files/Android/data/com.example.pathways.testipcam/files/Movies/IPcam_20190116_150628_6019720208966811003.m>kv]
java.io.IOException: Cannot run program "/data/user/0/com.example.pathways.testipcam/files/ffmpeg": error=2, No such >file or directoryOK I’m trying to learn how to record and stream my IP cam on android. I can stream the video in a surface view media player no problem so I then went to the record task. Now I’m a bit lost. I know this is possible as I have read people say they used this to do it.
I started with implamenting
implementation 'nl.bravobit:android-ffmpeg:1.1.5'But I can’t figure out what I am missing or doing wrong as there aren’t really any tutorials explaining this completely. So hopefully this can be the thread everyone else finds for a solution. I have listed my code below. Exactly what have I got wrong here. It runs and goes to onStart...then right on onFailure.
DO I need to have 2 streams in order to view and watch ? or what the deal.
I know FFmpeg can do that.
"ffmpeg supports multiple outputs created out of the same input(s) in the same process. The usual way to accomplish this is :ffmpeg -i input1 -i input2 \
-acodec … -vcodec … output1 \
-acodec … -vcodec … output2 \"but I have no idea how to sue that.
Anyway, I know I’m kind of close, at least I hope I need a little help on getting over the finish line on this. What have I done wrong, how does this work.Here is what I did, I streamed the video as the app does. no problem
surfaceView = (SurfaceView) findViewById(R.id.videoView);
_surfaceHolder = surfaceView.getHolder();
_surfaceHolder.addCallback(this);
_surfaceHolder.setFixedSize(320, 240);
....
@Override
public void surfaceCreated(SurfaceHolder holder) {
mpPlayerRun();
}
public void mpPlayerRun(){
_mediaPlayer = new MediaPlayer();
_mediaPlayer.setDisplay(_surfaceHolder);
try {
// Specify the IP camera's URL and auth headers.
_mediaPlayer.setDataSource(RTSP_URL);
// Begin the process of setting up a video stream.
_mediaPlayer.setOnPreparedListener(this);
_mediaPlayer.prepareAsync();
}
catch (Exception e) {}
}
...
@Override
public void onPrepared(MediaPlayer mp) {
_mediaPlayer.start();
}OK, so then I created a button to record.
@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.IPcamback:
break;
case R.id.IPcamrecord:
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
takeIPvid();
} else {
requestIPCamPermission();
}.....
requested permission then results.
private void requestIPCamPermission() {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
new AlertDialog.Builder(this)
.setTitle("Permission needed")
.setMessage("This permission is needed do to android safety protocol")
.setPositiveButton("ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
ActivityCompat.requestPermissions(MainActivity.this,
new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE}, 420);
}
})
.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.create().show();
} else {
ActivityCompat.requestPermissions(this,
new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE}, 420);
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == 420) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
takeIPvid();
} else {
Toast.makeText(this, "Permission DENIED", Toast.LENGTH_SHORT).show();
}
.....then I made the file provider and createVideoOutputFile() method and the takeIPvid method.
private File createVideoOutputFile() throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "IPcam_" + timeStamp + "_";
IPstorageDir = getExternalFilesDir(Environment.DIRECTORY_MOVIES);
IPvideo_file = File.createTempFile(
imageFileName, /* prefix */
".mp4", /* suffix */
IPstorageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
String IPmVideoFilename = IPvideo_file.getAbsolutePath();
return IPvideo_file;
}
private void takeIPvid() {
File ipfile = null;
try {
ipfile = createVideoOutputFile();
} catch (IOException e) {
e.printStackTrace();
}
IPvideo_uri = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
ipfile);
String[] cmd = {"-y", "-i", "rtsp://Login:Passord@IP:port/video.h264", "-acodec", "copy", "-vcodec", "copy","-t","00:00:20", IPvideo_uri.toString() };
FFmpeg.getInstance(this).execute(cmd,new ExecuteBinaryResponseHandler(){
@Override
public void onStart() {
super.onStart();
}

super.onFailure(message);
}

}
@Override

Audio & Video not synchronized properly if i merged more videos in mp4parser
1er octobre 2013, par maniyaI have used mp4parser for merging video with dynamic pause and record video capture for max 6 second recording. In preview its working fine when recorded video with minimum pause/record, If i tried with more than 3 pause/record mean the last video file not get merged properly with audio.At the start of the video the sync is ok but at the end the video hanged and audio playing in screen for the remaining file duration about 1sec.

How to get picture buffer data in ffmpeg ?
5 juin 2014, par 4ntoineI’m trying to pass bitmap from ffmpeg to android.
It already works but it’s displaying picture right on surface passed from java to native code.
How can i get frame buffer bitmap data to pass it to java ?I’ve tried to save out_frame buffer data :
unsigned char bmpFileHeader[14] = {'B', 'M', 0,0,0,0, 0,0, 0,0, 54, 0,0,0};
unsigned char bmpInfoHeader[40] = {40,0,0,0, 0,0,0,0, 0,0,0,0, 1,0, 24,0};
unsigned char bmpPad[3] = {0, 0, 0};
void saveBuffer(int fileIndex, int width, int height, unsigned char *buffer, int buffer_size) {
unsigned char filename[1024];
sprintf(filename, "/storage/sdcard0/3d_player_%d.bmp", fileIndex);
LOGI(10, "saving ffmpeg bitmap file: %d to %s", fileIndex, filename);
FILE *bitmapFile = fopen(filename, "wb");
if (!bitmapFile) {
LOGE(10, "failed to create ffmpeg bitmap file");
return;
}
unsigned char filesize = 54 + 3 * width * height; // 3 = (r,g,b)
bmpFileHeader[2] = (unsigned char)(filesize);
bmpFileHeader[3] = (unsigned char)(filesize >> 8);
bmpFileHeader[4] = (unsigned char)(filesize >> 16);
bmpFileHeader[5] = (unsigned char)(filesize >> 24);
bmpInfoHeader[4] = (unsigned char)(width);
bmpInfoHeader[5] = (unsigned char)(width >> 8);
bmpInfoHeader[6] = (unsigned char)(width >> 16);
bmpInfoHeader[7] = (unsigned char)(width >> 24);
bmpInfoHeader[8] = (unsigned char)(height);
bmpInfoHeader[9] = (unsigned char)(height >> 8);
bmpInfoHeader[10] = (unsigned char)(height >> 16);
bmpInfoHeader[11] = (unsigned char)(height >> 24);
fwrite(bmpFileHeader, 1, 14, bitmapFile);
fwrite(bmpInfoHeader, 1, 40, bitmapFile);
