Encodage et transformation en formats lisibles sur Internet
10 avril 2011MediaSPIP transforme et ré-encode les documents mis en ligne afin de les rendre lisibles sur Internet et automatiquement utilisables sans intervention du créateur de contenu.
Les vidéos sont automatiquement encodées dans les formats supportés par HTML5 : MP4, Ogv et WebM. La version "MP4" est également utilisée pour le lecteur flash de secours nécessaire aux anciens navigateurs.
Les documents audios sont également ré-encodés dans les deux formats utilisables par HTML5 :MP3 et Ogg. La version "MP3" (...) -

Decoding an mp3 file using FFmpeg but sound is glitchy

The sound on my S4 working but it’s glitchy and stuttering

Progress Bar findviewbyid returns null

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();
