I am planning to write an application (C/C++/Objective-C) that will play media files in own (private) container format. The files will contain: multiple video streams, encoded by a video codec (like XVid or H264, it is supposed, that components capable of decoding the viideo formats are present in the system); multiple audio streams in s...
Hi, I'm not seeing the text for my UITableView show up.. in fact the TableView doesn't appear to be on the screen at all because I cannot select the empty rows.
