im doing 2 pass encode on uploads site. unfortunately when user uploads 6 audio channel .mkv files (5.1 surround), ffmpeg spits out following error: resampling input channels greater 2 unsupported. im running latest version of ffmpeg. doing -ac 6 instead of usual - ac 2 proceeds encoding, creates larger file useless data, creates step in long file processing script, , i'd rather avoid modifying conversion command. is there can make -ac 2 work? it known bug/limitation of current ffmpeg. in experience concluded can't done ffmpeg alone. you have transcode audio/video separately. 1) extract .wav file source movie. 2) resample 2ch stereo audio editing tool such audacity . 3) encode audio stream 3) transcode video stream 4) mux audio/video target format

we're in middle of tidying our codebase (among other things) fixing compiler warnings. the end goal turn on flag converts warnings errors. we've run slight snag system , thirdparty headers. of system headers cause various compilers emit warnings. can't go modifying system headers fix warnings. with intel compiler (and gcc) use -isystem instead of -i when building include path tell compilers headers in dirs system headers , stops warning them. it's simple matter of turning on -werror flag. we're using sun studio 12, flag -errwarn=%all should equivalent of -werror, can't find way tell compiler ignore warnings in system / thirdparty headers. there -errhdr flag, doesn't seem want. does know how accomplish sun studio 12? obviously, isn't want in absence of better wrap offending includes in #pragma error_messages block. e.g. #pragma error_messages (on , tag .. tag) #include <map> // etc #pragma error_messages (default , tag...

i need produce functions allow me store , retrieve date ranges. evaluate dates based on todays date, add them array. i'm not sure how many ranges i'll need keep. perhaps you've seen similar example of can use reference? edit. need save them use when app next run too. you can represent date range in 2 ways: start date + end date start date + duration you can represent date nsdate instance, double (or, if desperately need save memory, int, unix timestamp). i'd make class that. @interface daterange : nsobject <nscoding> { nstimeinterval start, end; } @property (nonatomic, assign) nsdate* startdate; @property (nonatomic, assign) nsdate* enddate; @property (nonatomic, assign) nstimeinterval duration; - (bool) containsdate: (nsdate *) date; @end @implementation daterange - (nsdate *) startdate { return [nsdate datewithtimeintervalsincereferencedate: start]; } - (void) setstartdate: (nsdate *) date { start = [date timeintervalsi...

i'm new in website , want ask questions c++ because i'm learning these days , i'm noob (i know c , java). i'm using stroustrup book still don't understand uses , differences between classes , namespaces. also did c programs subject (operating systems) , want join of them in c++ program. idea have creat modules (because programs rely on different purpose). , have "main.cpp" file it's defined function called several times modules, check if module available , if so, can choose function of module want (depending on parameter passed). but problem don't know what's better way that. should use? classes or namespaces? , how can design? thought using design following: main.cpp --> modulea.cpp (implement interfacea.h) --> moduleb.cpp (implement interfaceb.h) --> modulec.cpp (implement interfacec.h) i searching on web other similar questions , found this one think it's complicate simple program. thank :) you wo...

i have 2d table structure reading underlying database, , wondering, best in-memory data-structure use store into. where, can accessible further reading, manipulation, etc. i maps of maps like map<string, map<string,string>> table = new hashmap<string, map<string,string>>(); here example column_a(primary), column_b, column_c -------------------------------- abc | xyz | 123 def | xxx | 456 so after read table use this: map.get("abc").get("column_b").equals("xyz") map.get("def").get("column_c").equals("456") hope helps. note: chose first map have key of string because table may not have integers ids. can change them if think integer fit better.

i have written jquery / js function "runs php query". function runquery(op){ if(op.type == "edit"){ var b = false; if(op.id != "" && (op.fromsong || op.tosong || op.when || op.comment)){ $.post("processor.php", { id: op.id, type: "edit", fromsong: op.fromsong, tosong: op.tosong, when: op.when, comment: op.comment }, function(data){ if(data == true){ console.log(true); b = true; }else{ console.log(false); b = false; } }); } return b; } i want return true of false depending on server answers. i'm sure php script working correctly , returning true or false correctly. every time run function console.log() outputs correct value, unlike variable b. seems alway false. doing wrong? since .ajax() call ( $.post wrapper $.ajax ) runs asyncronously , variable b return false . best thing "workaround" pass in call...

i've been working on program, , decided turn on optimizations using g++ -o3 . suddenly, program started segfaulting. i've hunted problematic code down, , minimized program still segfaults (only when using level 3 optimizations). hoping take quick peek @ code (i tried minimizing as possible): // src/main.cpp #include "rt/lights/point.hpp" int main(int argc, char **argv) { rt::light *light = new rt::light::point(alg::vector(.0f, 5.0f, 5.0f), rt::color(1.0f), .5f); return 0; } // include/rt/lights/point.hpp #ifndef rt_light_point_hpp_ #define rt_light_point_hpp_ #include "rt/accelerator.hpp" #include "rt/color.hpp" #include "rt/intersection.hpp" #include "rt/light.hpp" // abstract namespace rt { namespace light { class point : public light { public: point(alg::vector pos, color color, float intensity) : light(intensity * color), pos(pos) {} color get_contrib(const intersection&, const accelerator...

i've set whole infrastructure meaning i've configure php amqp extension http://www.php.net/manual/en/book.amqp.php . i've set durable exchange , queue. know should publish message delivery_mode = 2 (or equivalent in php) according http://www.rabbitmq.com/tutorial-two-python.html . don't know if can , if don't know how. $message = new amqpmessage(serialize($object), array('content_type' => 'text/plain', 'delivery_mode' => 2)); this using http://code.google.com/p/php-amqplib/ , guess native extension has similar syntax.

i kinda new objective-c , iphone development , have question. i'm creating app retrieved data internet using json-rpc. i've created json-rpc client performs requests , passes down results using delegate. however need use client quite few times in application, have been thinking. best way share client resource? understanding (from i've read far @ least) have following options: instantiate seperate client on each of controllers need access remote data pass instantiated client down on each new controller instance add client appdelegate create singleton of client , use that use global variable 1,2 options seem waste of resources. i've been reading 3,5 not best way go. leaves 4. don't think can use singleton delegates. should switch nsnotification? is there other way go about? from understand, trying want connect server on internet multiple times download data? if should use nsurlconnection class , create nsurlconnection object each time reques...

i hope create iphone window based app retina screen? found size of window in mainwindow.xib fixed. how adjust or there tell interface builder create window retina pixel size? welcome comment thanks interdev there's no need in terms of various components layout in interface builder, it's based around points, not pixels - , iphone screens sizes same in points no action required. in terms of images you're loading, need supply higher resolution (twice pixel size) versions, long these named "[original name]@2x.[extension]" they'll work automatically. for more information on image naming, see "specifying high-resolution images in ios" section of resource programming guide , if want delve little deeper, there's discussion on "points versus pixels" within drawing , printing guide ios . update - of iphone 5, iphone screens no longer same point size. :-)
