Recently purchased a brand New iPad device 4, which is no different from iPad 3, and, of course, the first thing taken care of, you need to put players to video in any format, To download TV series, filled and then look in the subway. Put the first thing AVPlayer. My favorite. He's doing very well, reproduce any audio and video format, but, unfortunately, can not play video from DLNA / Samba / nfs / WebDAV servers. For these purposes, I decided to put Goodplayer, naturally, latest. But was surprised, that half of the video was not of sound! And because everything is, that the developers removed the AC3 codec support in connection with the application owner!
As can be seen on this picture, I did not lie. But there is good news! AVPlayer these changes have not touched!
Therefore, beware, Read the changelog before, as updated! Otherwise you'll have to go back to the old version of the application by any known means to you! And if you bought these apps, it is generally impossible (Well if you do not have backups you purchased applications). This is especially true touch free player type iMedia Player, Older versions of which network it will be difficult to find, because, generally, no one will be spread on individual sites links to download the application, and so is free from an official source.
Well, it's time references!
