we looking @ writing android app , need create 2 copies of video record. each 1 require different settings (dimensions, etc). 1 'high quality' version (1280x720, high bitrate) , 1 'low quality' version (480x360, lower bitrate). both mp4 files. we have found using mediarecorder record higher quality version , using ffmpeg convert video afterwards lower quality version excruciatingly slow. getting speeds of 6 minutes 22 second video converted! so possible have 2 instances of mediarecorder @ once stream captured , encoded file on-the-fly, saving need encode after it's completed? alternatively there other suggestions how can achieve this, or maximise ffmpeg's performance?

i came across following lines in matlab : m = dir(fullfile(dataset,'*.png')); m = {m(~[m.isdir]).name}; i understand first line trying obtain .png files directory. but, second line trying perform? isdir seems determine input directory. that's new part. but, line trying perform? thanks. the second line getting files not directory , getting respective names , storing them cell array m.isdir indicates if folder or not returns 1 if is, 0 if not. ~[m.isdir] indicate of values returned isdir 0. m(~[m.isdir]) grabs objects in m determined logical indexing done above m(~[m.isdir]).name gets names of of them {m(~[m.isdir]).name} stores them in cell array hopefully step step walkthrough helps. while not sure why second line necessary because fullfile(dataset,'*.png') should return paths end in .png , not folder, guess check.

so - have bunch of instances of class , there's function want call on of them. i'm wondering if rather loop through every instance have, there way can declare function on class when called runs on each instance? example - if class looks this: public class myclass{ public var variable:string = ""; public function myclass(){} public function myfunction():void{ this.variable = "blore"; } } and have bunch of these: var class1:myclass = new myclass(); var class2:myclass = new myclass(); is there way can call myclass.myfunction() , have called on of instances? i don't know if i'm explaining well...but there is. i'd love suggestions have don't involve "put instances in array or vector , loop through them real man." here's quick example of how accomplish this: package { public class example { public static var instances:array; public function example() { ...

i've got several python applications consisting of scripts/modules should packaged , deployed rpms. the trickier bit each application should distributed along python module dependencies, , these should used in preference installed system wide. the target hosts of these rpms have limited network access, rpms should contain needed run app, rather downloading @ deploy time. i've looked @ packaging , distributing virtualenv , relocating virtualenv doesn't seem supported. i've looked @ zc.buildout , found documentation lacking. see how download dependencies during development, not how distribute them part of larger application. it's possible different apps require different versions of same module, these shouldn't installed system wide. another pain point python scripts in app need modified use different sys.path during development , after deployment, couldn't see obvious way around this. are suggestions on how best achieve this? ideal summary of ...

i'd write : class test def initialize(a,b,c) end def print() puts @a puts @b puts @c end end test.new({a=>1, b=>2, c=>3}).print() =>1 =>2 =>3 is there way instanciate object , map parameters hash table? thanks in advance. class test def initialize(options) options.each |key, value| instance_variable_set("@#{key}", value) end end def print puts @a puts @b puts @c end end test.new(:a => 1, :b => 2, :c => 3).print or use openstruct : http://www.ruby-doc.org/stdlib-1.9.3/libdoc/ostruct/rdoc/openstruct.html here's simple example: require 'ostruct' puts openstruct.new(:a => 1, :b => 2, :c => 3).inspect # outputs: "#<openstruct a=1, b=2, c=3>"

i have users table of 76 users , usergroups table. using mvc, odata, generic repository , ef, trying optimize data retrieval when filtering based on user group: /api/users?$filter=usergroups/any(usergroup: usergroup/id eq 'group1') on client side, right number of users - 71 (as odata filtering based on result), want limit number of records being returned form actual query - ie. not want return records filter (not optimal large data sets). my api controller method follows: [queryable(allowedqueryoptions = allowedqueryoptions.all)] public iqueryable<user> get() { var unitofwork = new atms.repository.unitofwork(_dbcontext); var users = unitofwork.repository<user>() .query() .include(u => u.usergroups) .get() .orderby(order => order.username); unitofwork.save(); // includes dispose() ...
