android - MediaFormat required for Mediacodec -

i trying decode h264 file using media codec. not straight supported android, configuring own decoder. i've attempted follow.

codec = mediacodec.createdecoderbytype("video/avc"); format.createvideoformat("video/avc", /*640*/320, /*480*/240); seek { codec.configure(format, null, null,0); } catch(exception codec) { log.i(tag,"codec_configure " +codec.getmessage()); } //codec.start(); codec.getinputbuffers(); codec.getoutputbuffers(); inputbuffers = codec.getinputbuffers(); outputbuffers = codec.getoutputbuffers();

i getting nullpointerexception @ format.creatvideoformat() , illegalstateexception @ codec.start()

could help me prepare it?

i sense createvideoformat

format = mediaformat::createvideoformat("video/avc", /*640*/320, /*480*/240);

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
