avcodec_decode_video2 RETURNS THE VALUE -1094995529 in the threaded function
2 février 2016, par WhoamiI am developing rtsp streaming player, and followed the below approach.
1) Read packet, decode, display -> works perfectly.

Progress Bar findviewbyid returns null
1er avril 2017, par ziad kiwanHelp me please it’s getting frustrating !
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 !
