and more , I can't add a text to the video(newsfeed). 

All these problems here in demo too

Yes, we are aware of the issue with the group newsfeed video as well as with the adding some comment of yours along with the video in the newsfeed, this already been reported. Please do the search before posting. 

"in my dashboard I can see videos I have posted, but there is no information where I have posted." 

What information where you have posted you're talking about? 

When you post  a link, for example, of a youtube video, in the friends' profile newsfeed. The video should be displayed, in friends' profile newsfeed, your dashboard newsfeed and main newsfeed on the index page. 

Please share your url so I can check the newsfeed posting behaviour on your website. 

christmas and new year are coming and I can't post videos to friends and groups. here in demo too . where is the problem?

Please answer the question above. You're not helping

1. youtbe url  my text

    video thumbnail

    my text disappears after I  posted.

 

and also it have be the place where  I posted , ex. user new video group xxxx

same with the pictures. If user  posted to a group, newsfeed is showing that user posted in the newsfeed album and not to a group

2. "The video should be displayed, in friends' profile newsfeed, your dashboard newsfeed and main newsfeed on the index page. "

in friends' profile newsfeedit isn;t displayed, also in groups are missing

3. I tried 3 new installs and same problem, I have tried here in demo, same problems. take look http://demo.oxwall.org/

  

   try to post video to the group

Yes we are aware of the issue with group videos and photos and that it should work independently from the other newsfeeds. 

We are also aware you cannot put the comments to the video while adding it via status bar in the newsfeed it just parses the video link not text

We have already passed to our developers. 

As to the Friend's profile newsfeed I was able to reproduce the issue, I will pass it to our developers it will be fixed asap. Thanks for the report

thank you ross 

No problem.
