ios - Streaming Technique from pocketcast in xcode -


i've been asked client whether possible download video , stream once bit has downloaded, pocketcasts does. reasoning allow him store video files on site such godaddy , bypass need stream file phone requires dedicated server.

is possible? if know anywhere can find out how pocketcasts it? @ moment app streams mp4.

thanks looking,

matt

since you're targetting ios, hls (http live streaming) friend: https://developer.apple.com/streaming/

please see answer here how can use it: simultaneously downloading , playing song pieced multiple urls

it's easy run long movie through mediafilesegmenter tool apple (or ffmpeg) spits out number of small .ts files (mpeg 2 transport stream). create manifest (a .m3u8 file) describes how these files fit (which mediafilesegment create too!). put manifest file , .ts files on hosting provider (like godaddy) , you're set.

for example, given file called test.mp4, first turn .ts file ffmpeg:

ffmpeg -i test.mp4 -acodec copy -vcodec copy -bsf h264_mp4toannexb test.ts

then turn series of hls segments mediafilesegmenter (the same can done using ffmpeg segment muxer, mediafilesegmenter seems more robust):

mediafilesegmenter -t 3 test.ts

the result bunch of 3 second clips (that's -t 3 means) , manifest file called prog_index.m3u8. contents of like:

#extm3u #ext-x-targetduration:3 #ext-x-version:3 #ext-x-media-sequence:0 #ext-x-playlist-type:vod #extinf:2.99520,     filesequence0.ts #extinf:2.99520,     filesequence1.ts #extinf:2.99520,     filesequence2.ts #extinf:2.99520,     filesequence3.ts ... #extinf:0.37440,     filesequence75.ts #ext-x-endlist

simply putting of .ts files , .m3u8 file on web server , pointing avplayer or mpmovieplayercontroller in ios @ url .m3u8 excellent streaming performance.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

java.util.scanner - How to read and add only numbers to array from a text file -

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
