forwardPlaybackEndTime does not work

由 痞子三分冷 提交于 2019-12-13 04:51:04
问题 AVPlayerItem has this property forwardPlaybackEndTime The value indicated the time at which playback should end when the playback rate is positive (see AVPlayer’s rate property). The default value is kCMTimeInvalid, which indicates that no end time for forward playback is specified. In this case, the effective end time for forward playback is the item’s duration. But I don't know why it does not work. I tried to set it in AVPlayerItemStatusReadyToPlay , duration available callback, ... but it

why does std::search need forward iters

由 喜欢而已 提交于 2019-12-12 08:11:38
问题 my issue is identical to the thread below, I'm struggling to understand the answers given, or rather my code shouldn't work as it only uses input iterators ..but my func appears to work and behave identically to std::search ..so I'm at a loss and loathe to move on without understanding properly ...maybe if someone can suggest an input that will break my function but not the std:: From Why do I need a Forward Iterator to implement my customized std::search : I am studying the book "Accelerated

Forwarding Outlook Item as attachment and adding it to a category in the same VBA macro

由 ⅰ亾dé卋堺 提交于 2019-12-12 05:12:42
问题 I have a macro that works for forwarding multiple Outlook items as attachments. I've pasted that below, but I want it to also add the forwarded message(s) to a category in outlook. So, not only would it forward the items that are in my inbox to the recipient, but it would also mark those items in a certain category. This way I could track which items I have forwarded using the macro. As it is now, it will show me the item has been forwarded on such and such date, but that may have been just a

Apache domainname instead of IP

由 不想你离开。 提交于 2019-12-12 03:52:52
问题 I'm not sure this is even a question to be asked here, but I'll give it a shot anyway. So I have an ubuntu server, and I recently purchased a domainname. Now I have forwarded the domain to my IP, but whenever I reach the server, the browser shows the IP adress instead of the domain. Is this something I should configure in Apache, or from godday (where I got the domainname) Thanks in advance :) 回答1: Start with checking your setup at Godaddy. What you probably need is an A entry.

How to determine from a filter which page serviced a forward from RequestDispatcher?

由 ╄→гoц情女王★ 提交于 2019-12-12 02:46:58
问题 I have a filter which processes requests in order to log them, so I can keep track of which session hit a page at what time with what request parameters. works great... posting from jsp to jsp, or making a direct call to a jsp. When a form is posted to a servlet which forwards that request to a new jsp, however, I am unable to see which jsp the request was forwarded to. For example, suppose I have a login page, which posts to a LoginServlet, which then forwards the request to either index.jsp

Forward Iterator C++ : for_each behavior

由 吃可爱长大的小学妹 提交于 2019-12-11 19:52:28
问题 So we know that foreach is something like : template<class InputIterator, class Function> Function for_each(InputIterator first, InputIterator last, Function f) { for ( ; first!=last; ++first ) f(*first); return f; } I have implemented a template <typename T> class Range The problem is that when I use this function with the for_Each : static void add1(float &v) { ++v; } it go in infinite loop because of first "!=" last (it's not first"<"last), so how people do when they implemente their own
