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".

i’m doing a chat application where i’m adding views to a linear layout programmatically each time a user press the send button the code is below :

}okay now to the problem when i call the findviewbyid for the progress bar in sendvideomessage ffmpeg onsuccess callback it returns null even though the findviewbyid for the the imageview which is in the same layout it returns the view ! so please tell me what is the problem
public void onSuccess(String message1) {
Log.w("Zipping","Success");
RelativeLayout v = (RelativeLayout) mEssageBox.findViewById(rowid.intValue()); ;
ProgressBar progressBar = (ProgressBar) v.findViewById(R.id.message_entity_Right_progressbar); // this keeps returning null!
ImageView iv = (ImageView) v.findViewById(R.id.message_entity_right_imageview); // returns the view
// progressBar.setVisibility(View.GONE);
Bitmap bitTh = ThumbnailUtils.createVideoThumbnail(ZippedVideoPath, MediaStore.Images.Thumbnails.MINI_KIND);
iv.setImageBitmap(bitTh);
progressBar.setVisibility(View.GONE);
iv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(ZippedVideoPath));
intent.setDataAndType(Uri.parse(ZippedVideoPath), "video/mp4");
startActivity(intent);
}
});
UploadVideo uv = new UploadVideo(v);
uv.execute();
}Thank you !

FFMPEG library's some command not working on android

For Fedding Effect :
"ffmpeg -i filename1 fade=in:5:8 output.mp4"For Concate Video Files :
"ffmpeg -i concat : filename1|filename2 -codec copy output.mp4"Error : App throws error like unknown command "concate" and "fad-in5:8".

Convert TS with closed captions into MKV/MP4 with sub title
28 mars 2017, par SudheeshI am trying to convert a TS file ( with US closed captions ) into MKV ( or MP4 ). Currently I am doing using a three step approach.
Step-1 : Extract the subtitle in srt format.
ffmpeg -f lavfi -i "movie=test.ts[out0+subcc]" -map s output.srt
Step-2 : Transcode the TS into MKV
ffmpeg i test.ts -vcodec libx264 -acodec copy out.mkv
Step-3 : Add subtitle back to out.mkv
ffmpeg -i out.mkv -i output.srt -acodec copy -vcodec copy -scodec copy final.mkv.
I believe all these three steps can be combined in a single ffmeg command. Is there any way to do this ?.
