ios - Reading from two files one after other using avassetreader -


What do I need to merge two movie files? I want to read from the files and write the sample in a different file. How can I read a file and then continue to read the second file. So that I can continuously get sample buffers which can be combined with AVAssetwritter. You need to create an AVMutableComposition, add an AVMutableCompositionTrack and then add each property to AVMutableCompositionTrack.

Here is another question that shows the process adequately.

Once you have AVMutableComposition, you have to associate it with your AVAssetReader. After that, what you are looking for is what it is.

However, if you just want to have a basic stitch (with audio), then note that using AVAssetExport avoids the need to bother with the asset reader and the assetverter and will export once In AVMutableComposition

Note that if you also want audio, then this is another track on your AVMutableComposition.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
